The SN74LXCH1T45 is an 1-bit, dual-supply noninverting bidirectional voltage level translation device with bus-hold circuitry. The I/O pin A and control pin (DIR) are referenced to VCCA logic levels, and the I/O pin B is referenced to VCCB logic levels. The A pin is able to accept I/O voltages ranging from 1.1 V to 5.5 V, while the B port can accept I/O voltages from 1.1 V to 5.5 V. A high on DIR allows data transmission from A to B and a low on DIR allows data transmission from B to A. See Device Functional Modes for a summary of the operation of the control logic.

AVCLVCDIRCNTRL-EVM — AVC 및 LVC를 지원하는 방향 제어 양방향 변환 디바이스를 위한 일반 EVM

The generic EVM is designed to support one, two, four and eight channel LVC and AVC direction-controlled translation devices. It also supports the bus hold and automotive -Q1 devices in the same number of channels. The AVC are low voltage translation devices with lower drive strength of 12mA. LVC (...)
