74LVCH245A

OCTAL BUS TRANSCEIVER WITH BUS HOLD / 3 STATE OUTPUTS

Description

Pin Assignments

The 74LVCH245A is an octal transceiver 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) pin can be used to disable the device so the buses effectively are

isolated.

The device is designed for operation with a power supply range of

1.65V to 3.6V.

The inputs are tolerant to 5.5V allowing this device to be used in a

mixed voltage environment. The device is fully specified for partial

power down applications using I_OFF. The I_OFFcircuitry disables the

output preventing damaging current backflow when the device is

powered down.

Bus hold circuitry holds unused or undriven inputs at a high or low

logic state. The use of external pull-up or pull down resistors is not

recommended.
