Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the application environment remains within the specified temperature range and voltage limits. Ensure proper handling procedures are followed due to ESD sensitivity specifications defined in JEDEC standards.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between TTL-driven sources and CMOS loads requiring high noise immunity. The wide operating temperature range supports demanding industrial environments. Verify that the propagation delay meets system timing requirements for the target bus architecture.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74HCT series, designed for compatibility with Transistor-Transistor Logic (TTL) inputs while utilizing Complementary Metal Oxide Semiconductor (CMOS) output characteristics. It provides low power dissipation and high noise immunity compared to older logic families.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74HC245PW,118 serves as a functional alternative but requires CMOS-compatible input drivers rather than TTL sources.
