概要

Description

The SN74AHCT125DR is a quad buffer/driver with 3-state outputs, part of the Advanced High-Speed CMOS (AHCT) logic family designed by Texas Instruments. It operates with a supply voltage range of 4.5V to 5.5V and is optimized for 5V applications. This device features four independent buffers with a 3-state output, controlled by individual output enable (OE) pins, allowing for high-speed data transmission and bus driving.
Key features include low power consumption and high noise immunity, making it suitable for interfacing with TTL logic levels. The AHCT family is known for its fast switching times and high output drive capability, which makes it ideal for driving loads that require high current. The SN74AHCT125DR is commonly used in applications like data buffering, level shifting, and bus interfacing in digital circuits. It's encapsulated in a small-outline integrated circuit (SOIC) package, facilitating easy integration into various electronic designs where space is a constraint.

Pinout

The SN74AHCT125DR is a quadruple bus buffer gate with 3-state outputs, commonly used in digital circuits. It comes in a 14-pin package. Here is a brief overview of its pin configuration and functions:
1. Pin Count: 14 pins
2. Pin Functions:
- VCC (Pin 14): Supply voltage.
- GND (Pin 7): Ground.
- A1-A4 (Pins 2, 5, 10, 13): Data inputs for each buffer.
- Y1-Y4 (Pins 3, 6, 9, 12): Data outputs corresponding to each input.
- OE1-OE4 (Pins 1, 4, 11, 14): Output enable pins for each buffer.
Each buffer is controlled independently by its output enable pin. When the OE pin is low, the corresponding output is enabled and follows the input signal. When the OE pin is high, the output goes to a high-impedance state, effectively disconnecting it from the circuit. This feature is useful in bus-oriented systems, allowing multiple devices to share the same data lines without interference.
