Datasheet

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 independently of the
clock input. Information on the data input is transferred to the nQ output on the
LOW-to-HIGH transition of the clock pulse. The nD 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 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-A114-A exceeds 2000 V
 MM JESD22-A115-A exceeds 200 V
 Specified from 40 Cto+85C and from 40 Cto+125C
