74AVC16373
Rev. 3 — 20 February 2018
16-bit D-type transparent latch; 3.6 V tolerant; 3-state
Product data sheet

General 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 nOE
should be tied to V
CC
through a pull-up resistor (Live Insertion).
A dynamic controlled output (DCO) circuitry is implemented to support termination line
drive during transient (see
Figure 5).

Features and benefits
•
Wide supply voltage range from 1.2 V to 3.6 V
•
Complies with JEDEC standards:
–
JESD8-7 (1.2 V to 1.95 V)
–
JESD8-5 (1.8 V to 2.7 V)
–
JESD8-1A (2.7 V to 3.6 V)
•
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 V
CC
and GND pins to minimize noise and ground bounce
•
Supports Live Insertion
