Replacement verdict
Compatible functional replacement candidate
The AD8113JSTZ and AD8114AST are both 16 × 16 high-speed analog crosspoint switch matrices from Analog Devices, sharing the same core signal-routing function, supply architecture, and serial control interface. However, they differ in package and thermal characteristics, so the AD8114AST should be treated as a functional candidate rather than a drop-in replacement; verify footprint, thermal, and switching-parameter requirements against the target design before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD8113JSTZ | AD8114AST | Why it matters |
|---|---|---|---|
| Matrix Configuration | 16 x 16 (256 crosspoints) | 16 x 16 (256 crosspoints) | Both are 16x16 crosspoint switches, so the switching matrix size is functionally equivalent for routing applications. |
| Package / Mounting | 80-LQFP (surface mount) | 80-LQFP (surface mount) | Package and footprint compatibility determine whether the parts can be dropped into the same PCB layout. |
| Operating Temperature Range | 0°C to +70°C | -40°C to +85°C | The wider industrial temperature range of the AD8114AST allows use in harsher environments where the commercial-grade AD8113JSTZ may not be rated. |
| Supply Voltage | ±5 V (dual supply) | ±5 V (dual supply) | Matching supply requirements means the same power rails can be used, simplifying substitution. |
| -3 dB Bandwidth | 60 MHz | 60 MHz | Bandwidth determines the maximum signal frequency the switch can pass with acceptable attenuation; identical values indicate equivalent high-frequency performance. |
| Channel-to-Channel Crosstalk | -70 dB (at 5 MHz) | -70 dB (at 5 MHz) | Crosstalk affects signal isolation between routed channels; equivalent values mean similar signal integrity in dense routing. |
| On Resistance | ~50 Ω | ~50 Ω | On resistance impacts signal loss and load matching; matching values support equivalent signal path behavior. |
| Control Interface | Parallel / serial control | Parallel / serial control | The control interface must match the host system's programming scheme for the part to be a functional substitute. |

Frequently asked questions
What are the primary differences between the AD8113JSTZ and the AD8114AST?
The AD8113JSTZ is a 16 × 16 crosspoint switch, while the AD8114AST is a 16 × 16 crosspoint switch with a different feature set. The AD8113JSTZ operates on ±5 V or +5 V supplies and provides a -3 dB bandwidth of 60 MHz, whereas the AD8114AST operates on ±5 V supplies and offers a -3 dB bandwidth of 225 MHz. The AD8113JSTZ is packaged in a 100-lead LQFP (STZ suffix), and the AD8114AST is packaged in a 100-lead LQFP (AST suffix). Both are manufactured by Analog Devices.
Are the AD8113JSTZ and AD8114AST pin-compatible?
No. Although both devices are housed in 100-lead LQFP packages, their pinouts differ. The AD8113JSTZ and AD8114AST have different pin function assignments, so they are not drop-in replacements for each other. PCB layouts must be designed specifically for the chosen device.
What are the supply voltage requirements for each device?
The AD8113JSTZ operates from ±5 V dual supplies or a single +5 V supply. The AD8114AST operates from ±5 V dual supplies. Designers should verify the exact supply range and current consumption in the respective Analog Devices datasheets before finalizing power supply designs.
How do the bandwidth specifications compare between the AD8113JSTZ and AD8114AST?
The AD8113JSTZ provides a -3 dB bandwidth of 60 MHz, while the AD8114AST provides a -3 dB bandwidth of 225 MHz. The AD8114AST is therefore better suited for higher-frequency signal routing applications, whereas the AD8113JSTZ is appropriate for lower-bandwidth crosspoint switching tasks.
Can the AD8113JSTZ and AD8114AST be used interchangeably in an existing design?
No. Due to differences in pinout, bandwidth, supply requirements, and other electrical characteristics, the two devices are not interchangeable without redesigning the PCB and revalidating the entire signal chain against the target device's datasheet.
What are the package and temperature range specifications for these devices?
Both the AD8113JSTZ and AD8114AST are offered in 100-lead LQFP packages. The AD8113JSTZ is specified for the commercial temperature range of 0°C to +70°C. The AD8114AST is specified for the industrial temperature range of -40°C to +85°C. Designers should confirm the exact temperature grade from the Analog Devices datasheet for their specific orderable part number.
Which device is more suitable for high-speed video or RF signal routing?
The AD8114AST, with its 225 MHz -3 dB bandwidth, is more suitable for high-speed video and RF signal routing than the AD8113JSTZ, which has a 60 MHz -3 dB bandwidth. The higher bandwidth of the AD8114AST supports wider signal spectra with less attenuation at higher frequencies.
