SN74LVCH245AZXYR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH245AZXYR is an octal bus transceiver from the Texas Instruments LVCH series, housed in a 20-pin BGA Microstar Junior package. It features bidirectional data flow with three-state outputs and operates within a supply voltage range of 1.65 V to 3.6 V. The device supports TTL/CMOS input levels and provides LVTTL output levels. Key electrical specifications include a propagation delay of 7 ns, low-level output current of 24 mA, and high-level output current of -24 mA. It functions reliably across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ZXYR' corresponds to the BGA Microstar Junior package and tape-and-reel orientation. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact manufacturer designation to avoid pinout or electrical mismatches during integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when space-constrained designs require an octal transceiver with low-voltage operation. The BGA Microstar Junior package offers a compact footprint suitable for high-density PCB layouts. Consider the 7 ns propagation delay and 24 mA drive capability against system timing and load requirements compared to standard SOIC alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the SN74LVCH245A family of low-voltage CMOS octal bus transceivers. It is designed for applications requiring bidirectional data transfer between buses operating at different voltage levels. The LVCH series emphasizes low power consumption and high speed while maintaining compatibility with standard logic families used in modern embedded systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVCH245ARGYRG4 (VQFN-20 package) and SN74LVCH245ADWR (SOIC-20 package) offer similar electrical characteristics but differ in physical footprint. Verify pin-to-pin compatibility and thermal performance before substituting these variants in existing designs.
