Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the exact manufacturer designation as Renesas Electronics Corporation or Texas Instruments, as both produce this part number variant. Confirm the suffix 'ELL' corresponds to the specific TSSOP-14 packaging and tape-and-reel configuration required for your assembly process. Ensure the component meets the specified -40°C to +85°C industrial temperature grade for your application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad buffer with TTL-compatible inputs is required for 5V logic systems. It is suitable for applications needing individual channel enable/disable functionality without external gating logic. Consider the TSSOP-14 package size for space-constrained PCB layouts. Verify that the 24 mA drive current capability meets the load requirements of the connected circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the 74ACT series, which offers higher speed than HC series devices while maintaining CMOS compatibility. The 74ACT125 specifically provides buffered outputs with enable controls, distinguishing it from unbuffered variants. It serves as a critical interface element in digital systems requiring signal integrity and noise immunity across automotive and industrial environments.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the input logic threshold compatibility?

The inputs are compatible with TTL logic levels, allowing direct interfacing with TTL-driven sources.

How is the output state controlled?

Each of the four channels has an individual active-low output enable pin; driving these pins low activates the respective buffers.
