SN74LVTH16245ADGG

Product Summary

The SN74LVTH16245ADGG is a 3.3V ABT 16-bit bus transceiver with 3-state outputs. The SN74LVTH16245ADGG is designed for low-voltage (3.3V) VCC operation, but with the capability to provide a TTL interface to a 5-V system environment. The SN74LVTH16245ADGG is designed for asynchronous communication between two data buses. The logic levels of the direction-control (DIR) input and the output-enable (OE) input activate either the B-port outputs or the A-port outputs or place both output ports into the high-impedance mode. The device transmits data from the A bus to the B bus when the B-port outputs are activated, and from the B bus to the A bus when the A-port outputs are activated. The input circuitry on both A and B ports is always active and must have a logic HIGH or LOW level applied to prevent excess ICC and ICCZ.
