74LV74

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

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.

Features and benefits

  • Wide supply voltage range from 1.0 V to 5.5 V

  • Optimized for low voltage applications from 1.0 V to 3.6 V

  • CMOS low power dissipation

  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

  • Direct interface with TTL levels (2.7 V to 3.6 V)

  • ESD protection:

    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

  • Specified from -40 °C to +85 °C and from -40 °C to +125 °C
