SN74LVCHR16245A - 16-Bit Bus Transceiver With 3-State Outputs

This 16-bit (dual-octal) noninverting bus transceiver is designed for 1.65-V to 3.6-V V_CC operation.

The SN74LVCHR16245A device is designed for asynchronous communication between data buses. The control-function implementation minimizes external-timing requirements.
