DESCRIPTION

This 16-bit universal bus driver is designed for 1.65-V

to 3.6-V VCC operation.

Data flow from A to Y is controlled by the output-enable (OE) input. The device operates in the transparent mode

when the latch-enable (LE) input is low. When LE is high, the A data is latched if the clock (CLK) input is held at

a high or low logic level. If LE is high, the A data is stored in the latch/flip-flop on the low-to-high transition of

CLK. When OE is high, the outputs are in the high-impedance state.

The output port includes equivalent 26-W series resistors to reduce overshoot and undershoot.

To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

The SN74ALVCH162334 is characterized for operation from -40°C to 85°C.
