SN74AVCH4T245PW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVCH4T245PW is a 4-bit dual-supply bus transceiver from the AVCH logic family, manufactured by Texas Instruments. It operates with supply voltages ranging from 1.2 V to 3.6 V on both ports A and B. The device features configurable voltage-level shifting and 3-state outputs. Key electrical parameters include a maximum propagation delay of 10.3 ns at 15 pF load, a data rate of 380 Mb/s, and output drive currents of ±12 mA. It functions within an operating temperature range of -40 °C to +85 °C and is housed in a 16-pin TSSOP package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the component meets the required thermal and electrical specifications for the target application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing systems requiring 4-bit bidirectional data transfer between different voltage domains. The dual-supply architecture allows flexible voltage configuration for Port A and Port B. Consider the 16-pin TSSOP package constraints for PCB layout and ensure the 3-state output requirements match the bus topology design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AVCH4T245 series, which includes variants such as SN74AVCH4T245PWR (reel), SN74AVCH4T245RSVR (UQFN), and SN74AVCH4T245D (SOIC). All variants share the same core logical function but differ in packaging and shipping formats. The PW suffix specifically denotes the plastic small-outline thin-shrink package.
