SN74AXCH2T45DTMR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AXCH2T45DTMR is a two-bit non-inverting bus transceiver from the AXC logic family, manufactured by Texas Instruments. It features configurable dual-rail power supplies (VCCA and VCCB) supporting voltage ranges from 0.65 V to 3.6 V. The device supports asynchronous communication with propagation delays ranging from 4 ns to 108 ns depending on supply conditions. It operates within an extended temperature range of -40°C to +125°C and utilizes an 8-pin X2SON package.
