DESCRIPTION
The 74AVCM162836 is a 20-bit universal bus driver. Data flow is
controlled by output enable (OE
(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).
