The SN74ALVCH16245DGGR is a 16-bit Bus Transceiver with 3-state outputs and designed for 1.65 to 3.6V VCC operation. This device is designed for asynchronous communication between two data buses. The logic levels of the direction-control input and the output-enable 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. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver. Active bus-hold circuitry holds unused or un-driven inputs at a valid logic state.

• Bus hold on data inputs eliminates the need for external pull-up/pull-down resistors
• 3ns at 3.3V Propagation delay (tpd)
• ±24mA Output drive at 3.3V
• Latch-up performance exceeds 250mA per JESD 17
• Green product and no Sb/Br
