74LCX125MX

74LCX125MX is a TI SN74LCX125MX quad buffer/line driver with 3-state outputs. It contains four non-inverting buffers with a common output-enable input. When OE is asserted, each Yn follows its input An; when OE is deasserted, all outputs go high impedance, allowing multiple devices to share a bus. Designed in the low-voltage LCX CMOS family for CMOS/TTL compatibility, it’s typically used to buffer signals, shift levels between domains, or isolate a bus. Package: 14-pin small-outline (MX) package. Pinout (typical): A1, A2, A3, A4; Y1, Y2, Y3, Y4; OE; VCC; GND. Important notes: verify the exact enable polarity, supply voltage range, and propagation delays in the datasheet for your target part and operating temperature.

Common equivalents (quad buffer with 3-state outputs):
- SN74LCX125 (Texas Instruments)
- SN74LVC125A / 74LVC125 (TI or NXP/Nexperia)
- 74HC125 (various vendors)
- 74HCT125 (TTL-compatible CMOS)
- 74LS125 (low-power Schottky)
Any vendor’s 74xx125 family with the same supply voltage and timing specs can substitute.

Here are the key features of 74LCX125MX:
- Quad buffer/line driver with four 3-state outputs
- Four independent input-enable pins (OE1–OE4), active-low
- Non-inverting buffers; outputs go to high impedance when disabled
- Ioff (partial-power-down) support to prevent back-powering
- Compatible with standard CMOS/TTL input levels; low-voltage CMOS LCX family
- Fast switching and low power consumption
- 14-pin MX package (surface-mount)
- Industrial temperature range (typical: -40°C to 85°C) (verify datasheet for exact range)
Note: Always check the specific datasheet for exact Vcc range and timing specs.

- Pin count: 14 pins (DIP-14/SO-14 package).
- Function: Quad buffer/line driver with 3-state outputs. It contains four noninverting buffers (A1→Y1, A2→Y2, A3→Y3, A4→Y4) each with its own active-low enable (OE1–OE4). When OE is low, the corresponding Y follows A; when OE is high, the output is high-impedance. Used to buffer and isolate signals.

- Manufacturer: Nexperia.
- What kind of company: A global semiconductor company (Dutch-based) that designs and manufactures discrete and logic devices, including standard CMOS logic ICs and buffers/drivers.

74LCX125MX is a quad buffer/line driver with tri-state outputs (OE). Common applications include:
- Data bus buffering and fan-out to multiple devices
- Bus isolation between MCU/CPU and peripherals
- Level shifting between voltage domains (low-voltage CMOS)
- Clock/data distribution with controlled tri-state enable
- Memory/interface buffering for address/data lines
- I/O expansion for microcontrollers/ASICs/DSPs
- General-purpose buffering in mixed-signal boards needing controllable high impedance
Note: Use where tri-state output control and fast, low-power buffering are required.

It’s an 8‑pin small-outline package (SOIC), i.e., an SOIC-8 package.
