DESCRIPTION
The 74AVCM162836 is a 20-bit universal bus driver. Data flow is controlled by output enable (OE), latch enable (LE) and clock inputs (CP). This product is designed to have an extremely fast propagation delay and a minimum amount of power consumption. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor (Live Insertion).
