SN74AVCH32T245ZKER

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVCH32T245ZKER is a 32-bit dual-supply bus transceiver from the Texas Instruments AVC logic family. It operates within a voltage range of 1.2 V to 3.6 V and features non-inverting logic with three-state outputs. The device utilizes a Microstar BGA package containing 96 pins, designed for surface-mount installation. It supports an operating temperature range from -40 °C to +85 °C and exhibits a maximum propagation delay of 6.2 ns at 1.5 V under a 15 pF load condition.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix ZKER against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure that the procurement source provides valid RoHS compliance records and original manufacturer traceability. Cross-reference the component marking with the datasheet pinout to prevent substitution errors during assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing circuits requiring extensive parallel data paths across different voltage levels. The 32-bit width reduces board space compared to cascading smaller transceivers. Confirm that the target application voltage falls within the specified 1.2 V to 3.6 V operational window to ensure reliable switching performance.
