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 VCC and
GND pins for minimize noise and
ground bounce.
• All data inputs have bushold.
(only 74AVCH16374)
• Power off disables 74AVC16374;
74AVCH16374 outputs, permitting
Live Insertion.
DESCRIPTION
The 74AVC(H)16374 is a 16-bit edge
triggeredflip-flopfeaturingseparate D-type
inputsforeach flip-flopand3-State outputs
for bus oriented applications. Incorporates
bushold data inputs which eliminate the
need for external pull-up resistors to hold
unused inputs.
This product is designed to have an
extremely fast propagation delay and a
minimum amount of power consumption.
Toensurethehigh-impedanceoutputstate
during power up or power down, OE
n
should be tied to VCC through a pullup
resistor (Live insertion).
A Dynamic Controlled Output (DCO)
circuitry is implemented to support
termination line drive during transient. See
graphs at this page for typical curves.
The74AVCH16374consist of2sections of
eightedge-triggeredflip-flops.Aclock (CP)
input and an output enable (OE) are
provided per 8-bit section
