This 8-bit (octal) noninverting bus transceiver uses two separate power-supply rails. The A port, VCCA, is dedicated to accepting a 5V supply level, and the configurable B port, which is designed to track VCCB, accepts voltages from 3V to 5V. This allows for translation from a 3.3V to a 5V environment and vice versa.

The SN74LVCC4245A device is designed for asynchronous communication between data buses. The SN74LVCC4245A device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so the buses effectively are isolated. The control circuitry (DIR, OE) is powered by VCCA.

This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. The VCC isolation feature is designed so that if either VCCA or VCCB is less than 100mV, both I/O ports enter a high-impedance state by disabling their outputs.

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.
