description

A8 10

This 8-bit (octal) noninverting bus transceiver

contains two separate supply rails; B port has

GND 11

GND 12

, which is set at 3.3 V, and A port has V

CCB

CCA

which is set at 5 V. This allows for translation from

a 3.3-V to a 5-V environment, and vice versa.

The SN74LVC4245A 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.

The SN74LVC4245A pinout allows the designer to switch to a normal all-3.3-V or all-5-V 20-pin ’245 device

without board re-layout. The designer uses the data paths for pins 2–11 and 14–23 of the SN74LVC4245A to

align with the conventional ’245 pinout.

The SN74LVC4245A is characterized for operation from –40°C to 85°C.
