Replacement verdict
Compatible functional replacement candidate
The AM26LV32EIDR and AM26LS32ACDG4 are both quad differential line receivers with similar logic functions, making the AM26LV32EIDR a viable functional replacement candidate for the AM26LS32ACDG4 in many designs. However, the AM26LV32EIDR operates from a 3.3 V supply while the AM26LS32ACDG4 is specified for 5 V operation, so supply voltage compatibility must be validated in the target application before substitution.

Key differences
Rows are prioritized by design impact. Highlighted values require attention during substitution.
Key electrical and mechanical differences between the two devices
| Parameter | AM26LV32EIDR | AM26LS32ACDG4 | Why it matters |
|---|---|---|---|
| Supply Voltage (Vcc) | 3.0 V to 3.6 V | 4.75 V to 5.25 V | The two devices operate on different supply rails (3.3 V vs 5 V), so they are not directly interchangeable in the same socket without supply changes. |
| Logic Family | LV (Low-Voltage) differential line receiver | LS (standard 5 V) differential line receiver | Family determines compatible logic levels and interfacing with surrounding circuitry. |
| Input Common-Mode Voltage Range | -0.3 V to 5.5 V (with Vcc = 3.3 V) | -7 V to +7 V | A wider common-mode range provides greater noise immunity and tolerance to ground potential differences between nodes. |
| Differential Input Threshold (Vth) | ±200 mV (typical) | ±200 mV (typical) | Threshold determines sensitivity to differential signals; both are similar, aiding signal detection consistency. |
| Propagation Delay | ~15 ns (typical) | ~20 ns (typical) | Propagation delay affects timing margins in high-speed data links; faster delay can improve timing budget. |
| Output Type | 3-state (tri-state) outputs | 3-state (tri-state) outputs | Tri-state outputs allow bus sharing; identical here so no substitution concern on this point. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Industrial temperature range suitability is identical, so environmental compatibility is preserved. |
| Package / Pin Count | SOIC-16 (16 pins) | SOIC-16 (16 pins) | Same package and pin count enables drop-in PCB footprint compatibility. |
| Number of Receivers | 4 receivers | 4 receivers | Channel count must match for functional equivalence; both provide four differential receivers. |
| ESD Protection (HBM) | ±15 kV (bus pins, typical) | ±2 kV (typical) | Higher ESD robustness improves field reliability and handling safety in harsh environments. |

Frequently asked questions
What are the key differences between the AM26LV32EIDR and AM26LS32ACDG4?
The AM26LV32EIDR is a low-voltage quad differential line receiver optimized for 3.3 V operation, while the AM26LS32ACDG4 is a quad differential line receiver designed for 5 V operation. The AM26LV32EIDR features a wider common-mode input range and is specified for 3.3 V supply systems, whereas the AM26LS32ACDG4 is specified for 5 V systems and is a direct replacement for the AM26LS32 family.
Are the AM26LV32EIDR and AM26LS32ACDG4 pin-compatible?
Both devices are offered in 16-pin SOIC (D) packages with the same pinout for the quad receiver functions, enabling similar PCB layouts. However, the AM26LV32EIDR is specified for 3.3 V operation and the AM26LS32ACDG4 for 5 V operation, so supply voltage and associated circuitry must be verified before substitution.
What supply voltage does each device require?
The AM26LV32EIDR operates from a 3.3 V nominal supply (typically 3.0 V to 3.6 V), while the AM26LS32ACDG4 operates from a 5 V nominal supply (typically 4.75 V to 5.25 V). The supply voltage must match the device specification for reliable operation.
Do both devices support RS-422 and RS-485 differential signaling?
Both are quad differential line receivers intended for balanced (differential) data transmission per RS-422 and RS-485 signaling standards. The AM26LV32EIDR is optimized for 3.3 V systems, and the AM26LS32ACDG4 for 5 V systems, so the choice depends on the system supply and common-mode requirements.
What is the common-mode input range of each receiver?
The AM26LV32EIDR features a wide common-mode input range of approximately -7 V to +7 V, suitable for 3.3 V differential bus applications. The AM26LS32ACDG4 also provides a wide common-mode input range (approximately -7 V to +7 V) for 5 V systems. Exact limits should be confirmed in the respective manufacturer datasheets.
Can the AM26LV32EIDR directly replace the AM26LS32ACDG4 in an existing 5 V design?
No. The AM26LV32EIDR is specified for 3.3 V operation and is not a drop-in replacement for a 5 V design using the AM26LS32ACDG4. Supply voltage, input thresholds, and output levels must be validated against the target system before any substitution.
What package options are available for these devices?
The AM26LV32EIDR is supplied in a 16-pin SOIC (D) package in tape-and-reel format. The AM26LS32ACDG4 is supplied in a 16-pin SOIC (D) package. Package dimensions and pin functions should be verified against the manufacturer datasheet for layout compatibility.
