The SN74ALB16245 is a 16-bit transceiver designed for high-speed, low-voltage (3.3-V) VCC operation. This device is intended to replace the conventional transceiver in any speed-critical path. The small propagation delay is achieved using a unity gain amplifier on the input and feedback resistors from input to output, which allows the output to track the input with a small offset voltage.

This SN74ALB16245 device can be used as two 8-bit transceivers or one 16-bit transceiver. It allows data transmission 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 that the buses are effectively isolated.

The SN74ALB16245 is characterized for operation from 40°C to 85°C.
