Description

General part information

SN74CBTLV3245A Series

The SN74CBTLV3245A provides eight bits of high-speed bus switching in a standard '245 device pinout. The low on-state resistance of the switch allows connections to be made with minimal propagation delay.

The device is organized as one 8-bit switch. When output enable (OE) is low, the 8-bit bus switch is on, and port A is connected to port B. WhenOEis high, the switch is open, and the high-impedance state exists between the two ports.

This device is fully specified for partial-power-down applications using Ioff. The Iofffeature ensures that damaging current will not backflow through the device when it is powered down. The device has isolation during power off.
