3 Description

This 16-bit (dual-octal) noninverting bus transceiver is designed for 1.65-V to 3.6-V VCC operation. The SN74LVCH16245A device is designed for asynchronous communication between data buses.

This device can be used as two 8-bit transceivers or one 16-bit transceiver. Active bus-hold circuitry holds unused or undriven data inputs at a valid logic state.
