The SN74LXCH8T245 is an 8-bit, dual-supply noninverting bidirectional voltage level translation device with bus-hold circuitry. Ax pins and control pins (DIR and OE) are referenced to VCCA logic levels, and Bx pins are referenced to VCCB logic levels. The A port 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 when OE is set to low. When OE is set to high, both Ax and Bx pins are in the high-impedance state. See Device Functional Modes for a summary of the operation of the control logic.

AVCLVCDIRCNTRL-EVM — 適用於方向控制雙向轉換裝置、支援 AVC 和 LVC 的通用 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 (...)
