SN74LVCHR16245AGR

Product Summary

The SN74LVCHR16245AGR is a 16-bit bus transceiver. This 16-bit (dual-octal) noninverting bus transceiver is designed for 1.65-V to 3.6-V VCC operation. The SN74LVCHR16245AGR is designed for asynchronous communication between data buses. The control-function implementation minimizes external-timing requirements. The SN74LVCHR16245AGR 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.

Parametrics
