1. General description
The 74LV74 is a dual positive edge triggered, D-type flip-flop. It has individual data (nD)
inputs, clock (nCP) inputs, set (nSD) and (nRD) inputs, and complementary nQ and nQ
outputs.
The set and reset are asynchronous active LOW inputs that operate indepe nde ntly of the
clock input. Information on the data input is transferred to the nQ output on the
LOW-to-H IGH transition of the clock pulse. The nD inputs must be stable one set-up time
prior to the LOW-to-HIGH clock transition, for predict able operation. Schmitt- trigger action
in the clock input makes the circuit highly tolerant to slower clock rise and fall times.
2. Features and benefits
Wide supply voltage range from 1.0 V to 5.5 V
Optimized for low voltage applications: 1.0 V to 3.6 V
Direct interface with TTL levels (2.7 V to 3.6 V)
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
Specified from 40 Cto+85C and from 40 Cto+125C
