74AHC74; 74AHCT74

Dual D-type ﬂip-ﬂop with set and reset; positive-edge trigger

Rev. 05 — 9 June 2008

Product data sheet

1. General description

The 74AHC74; 74AHCT74 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 74AHC74; 74AHCT74 is a dual positive-edge triggered, D-type ﬂip-ﬂop with individual

data inputs (D), clock inputs (CP), set inputs (SD) and reset inputs (RD). It also has

complementary outputs (Q and Q).

The set and reset are asynchronous active LOW inputs that operate independent of the

clock input. Information on the data input is transferred to the Q output on the LOW to

HIGH transition of the clock pulse. The data inputs must be stable one set-up time prior to

the LOW to HIGH clock transition for predictable operation.

Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock

rise and fall times.

2. Features

I Balanced propagation delays

I All inputs have Schmitt-trigger actions

I Inputs accept voltages higher than V_CC

I Input levels:

N For 74AHC74: CMOS level

N For 74AHCT74: TTL level

I ESD protection:

N HBM EIA/JESD22-A114E exceeds 2000 V

N MM EIA/JESD22-A115-A exceeds 200 V

N CDM EIA/JESD22-C101C exceeds 1000 V

I Multiple package options

I Speciﬁed from −40 °C to +85 °C and from −40 °C to +125 °C
