SN74LVCC4245ADW

Приемопередатчик по шине с настраиваемым выходным напряжением и выходами на 3 состояния.

The SN74LVCC4245ADW is an Octal Bus Transceiver with adjustable output voltage and 3-state outputs. This 8-bit non-inverting bus transceiver uses two separate power-supply rails. The A port, VCCA, is dedicated to accept a 5V supply level and the configurable B port, which is designed to track VCCB, accepts voltages from 3 to 5V. This allows for translation from a 3.3 to a 5V environment and vice versa. The SN74LVCC4245A is designed for asynchronous communication between data buses. The 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 OE\ input can be used to disable the device so the buses are effectively isolated. The control circuitry (DIR, OE\) is powered by VCCA.
