DESCRIPTION
The 74AVC16836A 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 V
CC
through a pullup resistor (Live Insertion).
A Dynamic Controlled Output (DCO) circuitry is implemented to
support termination line drive during transient. See the graphs on
page 8 for typical curves.
