SN74LVCH245N

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH245N is an octal bus transceiver from the Texas Instruments LVCH logic series, housed in a 20-pin PDIP package. It features three-state outputs and operates within a supply voltage range of 2 V to 3.6 V. The device supports TTL/CMOS input levels and provides LVTTL output levels. Key electrical parameters include a propagation delay of 7 ns, with low-level and high-level output currents of 24 mA and -24 mA respectively. It functions as a non-inverting bidirectional transceiver suitable for general-purpose data transmission applications.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'N' corresponds to the 20-pin Plastic Dual In-Line Package (PDIP) variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors, as environmental certifications may vary by production batch. Ensure the ordering part number matches the required package style and temperature rating specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring robust 8-bit bidirectional data transfer with standard DIP packaging for prototyping or through-hole assembly. The LVCH series offers improved performance over legacy LS/TTL families while maintaining compatibility. Consider the 2V to 3.6V operating range to ensure adequate noise margins for the target system voltage.
