FEATURES
• Wide supply voltage range from 1.2 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
• Dynamic Controlled Output (DCO) circuit dynamically
changes output impedance,resulting in noise reduction
without speed degradation
• Low inductance multiple VCCand GND pins to minimize
noise and ground bounce
• Supports Live Insertion.
DESCRIPTION
The 74AVC16373 is a 16-bit D-type transparent latch
featuring separate D-type inputs for each latch, and
3-state outputs for bus oriented applications. One Latch
Enable (LE) input and one Output Enable (OE) input are
provided per 8-bit section. The 74AVC16373 consist of
two sections of eight D-type transparent latches with
3-state true outputs.
The 74AVC16373 is designed to have an extremely fast
propagation delay and a minimum amount of power
consumption.
To ensure the high-impedance output state during
power-up or power-down, pin OEn should be tied to V
through a pull-up resistor (Live Insertion).
A Dynamic Controlled Output (DCO) circuitry is
implemented to support termination line drive during
transient (see Figs 1 and 2).
