SN74LS442N

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LS442N is a quadruple tridirectional bus transceiver from the Texas Instruments SN74LS series. It features four independent bidirectional data channels with separate direction control inputs for each channel, allowing flexible data flow management between two buses. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports through-hole mounting in a standard 20-pin DIP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the component matches the SN74LS442N designation and the 20-pin PDIP package configuration. Confirm the logic family is LS (Low-power Schottky) and ensure the operating temperature range aligns with commercial requirements. Check for any specific ordering suffixes that may indicate variations in packaging or testing standards.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring multiple independent bidirectional data paths with individual direction control. It is suitable for applications needing flexible bus architecture where data flow direction must be managed per channel rather than globally across all lines simultaneously.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LS44x family of quadruple tridirectional bus transceivers. It shares functional similarities with the SN74LS440, SN74LS441, and SN74LS444, differing primarily in pinout configurations and specific application optimizations while maintaining the same core bus transceiver functionality and LS logic characteristics.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include the SN74LS440N, SN74LS441N, and SN74LS444N. Verify pin compatibility before substitution as these variants share the same logical function but differ in physical pin arrangements.
