SN74LVT245BPWR

Приемопередатчик, неинвертирующий, 2.7В до 3.6В, TSSOP-20.

The SN74LVT245BPWR is an octal Bus Transceiver designed specifically for low-voltage (3.3V) VCC operation, but with the capability to provide a TTL interface to a 5V system environment. It 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 output-enable (OE)\ input can be used to disable the device so the buses are effectively isolated. To ensure the high-impedance state during power up or power down, OE\ should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver. The IOFF circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down, which prevents driver conflict.
