74LV74
Dual D-type flip-flop with set and reset; positive-edge trigger
Rev. 5 — 24 March 2021
Product data sheet
1. General description
The 74LV74 is a dual positive edge triggered D-type flip-flop with individual data (nD), clock (nCP),
set (nSD) and reset (nRD) inputs, and complementary nQ and nQ outputs. Data at the D-input that
meets the set-up and hold time requirements on the LOW-to-HIGH clock transition will be stored
in the flip-flop and appear at the nQ output. Inputs include clamp diodes. This enables the use of
current limiting resistors to interface inputs to voltages in excess VCC
.
2. Features and benefits

Definitions
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those
given in the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
