74AVC16374
16-bit edge triggered D-type flip-flop; 3.6 V tolerant; 3-state
Rev. 3 — 16 August 2013
Product data sheet
1. General description
The 74AVC16374 is a 16-bit edge triggered flip-flop featuring separate D-type inputs for
each flip-flop and 3-state outputs for bus-oriented applications. The 74AVC16374 consist
of 2 sections of 8 edge-triggered flip-flops. A clock input (CP) and an output enable (OE)
are provided per 8-bit section.
The 74AVC16374 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, nOE should
be tied to VCC 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
and
Figure 6).
2. 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
