Application field of the M74HC125B1R

The M74HC125B1R is designed for bidirectional data transmissions in high-speed memory and display applications. The ideal applications for this device include bus line driving, buffer and line receiver, and searching control.In high-speed memory applications, the device is able to drive a bus line for data latches, sense amplifiers and sampling signals.

The device is also used in display applications as a buffer/receiver between a microprocessor and video displays. In search control applications, the M74HC125B1R is an ideal choice for data and address buffers, power buffer and clock bi-directional buffer.

Working principle of the M74HC125B1R

The M74HC125B1R consists of four independent three-state outputs. An active LOW Output Enable input is used to control the function of all four outputs. When the Output Enable Input is LOW, the output is enabled and the logic levels at the Data Input pins result in levels at the output pins. When the Output Enable Input is HIGH the logic levels at the input pins are ignored and the outputs are set in a High Impedance state.

This logic device features very high noise immunity, a high current capability, and a low output-enable power dissipation. It also features clamp diodes for transient suppression, which makes it ideal for use with TTL logic levels and other logic families.
