Présentation

Description

The 74HC125PW is a high-speed CMOS quad buffer/line driver with 3-state outputs. It is part of the 74HC logic family and is designed to operate with a wide voltage range, typically from 2V to 6V, making it suitable for various digital applications. The device contains four independent buffer line drivers, each with its own 3-state output. These outputs can be set to a high impedance state, allowing for multiple devices to share the same output line without interference. This feature is useful for bus-oriented systems.
The 74HC125PW is designed for low power consumption and high noise immunity. It typically operates at a fast switching speed, making it suitable for high-speed data transfer applications. The device is available in a TSSOP (Thin Shrink Small Outline Package) form factor, which aids in saving space on printed circuit boards (PCBs).
Common applications include signal buffering and driving, logic level shifting, and bus control in microcontroller and microprocessor systems. Its robust design ensures reliable operation in various electronic applications.

Equivalent

The 74HC125PW is a quad buffer/line driver with 3-state outputs. Equivalent products include 74HCT125, SN74HC125 by Texas Instruments, NXP's own 74HC125D, and ON Semiconductor's MC74HC125. These chips perform similar functions and are often interchangeable in designs, but specific electrical characteristics should be reviewed to ensure compatibility with your application.

Pinout

The 74HC125PW is a quad buffer/line driver with 3-state outputs. It is part of the 74HC series, which is a family of high-speed CMOS logic ICs. The device comes in a TSSOP-14 package, which means it has 14 pins.
Here is a brief overview of the pin functions:
1. VCC (Pin 14): Positive supply voltage.
2. GND (Pin 7): Ground.
3. A1 to A4 (Pins 2, 5, 10, 13): Data inputs for buffers 1 to 4.
4. OE1 to OE4 (Pins 1, 4, 9, 12): Output enable inputs for the corresponding buffers, active LOW.
5. Y1 to Y4 (Pins 3, 6, 8, 11): 3-state outputs for buffers 1 to 4.
Each buffer has an independent output enable, allowing selective control of data flow. When the output enable is LOW, the buffer is active, and the data at input A is transferred to the output Y. When the output enable is HIGH, the output Y goes into a high-impedance state, effectively disconnecting it from the circuit.
