74AHC374; 74AHCT374
Octal D-type flip-flop; positive edge-trigger; 3-state
Rev. 03 — 12 June 2008
Product data sheet
1. General description
The 74AHC374; 74AHCT374 is a high-speed Si-gate CMOS device and is pin compatible
with Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard
No. 7-A.
The 74AHC374; 74AHCT374 comprises eight D-type flip-flops featuring separate D-type
inputs for each flip-flop and 3-state outputs for bus oriented applications. A clock input
(CP) and an output enable input (OE) are common to all flip-flops.
The eight flip-flops will store the state of their individual D inputs that meet the set-up and
hold times requirements for the LOW-to-HIGH CP transition.
When OE is LOW the content of the eight flip-flops is available at the outputs. When OE is
HIGH, the outputs go to the high-impedance OFF-state. Operation of the OE input does
not affect the state of the flip-flops.
2. Features

I All inputs have Schmitt-trigger actions
I Inputs accept voltages higher than VCC
I Common 3-state output enable input
I Input levels:
N For 74AHC374: CMOS level

[1] Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V).
[2] tpd is the same as tPLH and tPHL
[3] ten is the same as tPZH and tPZL
[4] tdis is the same as tPHZ and tPLZ
.

.
[5] CPD is used to determine the dynamic power dissipation (PD in µW).
PD = CPD × VCC2 × fi × N + Σ(CL × VCC2 × fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;
VCC = supply voltage in V;
N = number of inputs switching;
Σ(CL × VCC2 × fo) = sum of the outputs.
