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 — AVC 및 LVC를 지원하는 방향 제어 양방향 변환 디바이스를 위한 일반 EVM
일반 EVM은 2개, 4개 및 8개 채널 LVC 및 AVC 방향 제어 변환 장치를 지원하도록 설계했습니다. 또한 동일한 개수의 채널에서 버스 홀드 및 차량용 -Q1 장치를 지원합니다. AVC는 구동 강도가 더 낮은 12mA인 저전압 변환 장치입니다. LVC는 구동 강도가 더 높은 32mA로, 1.65~5.5V의 더 높은 전압 변환 장치입니다.
