853-2212 24282
FEATURES
Wide supply voltage range of 1.2 V to 3.6 V
Complies with JEDEC standard no. 8-1A/5/7.
CMOS low power consumption
Input/output tolerant up to 3.6 V
DCO (Dynamic Controlled Output) circuit dynamically changes
output impedance, resulting in noise reduction without speed
degradation
Low inductance multiple V
CC
and GND pins for minimum noise
and ground bounce
Power off disables 74AVC16334A outputs, permitting Live
Insertion
Integrated input diodes to minimize input overshoot and
undershoot
Full PC133 solution provided when used with PCK2509S or
PCK2510S and CBT16292
DESCRIPTION
The 74AVC16334A is a 16-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.
