HEF4043B

Quad R/S latch with 3-state outputs

The HEF4043B is a quad R/S latch with 3-state outputs and common output enable input (OE). Each latch has set (nS), and reset (nR) inputs and a 3-state output (nQ). When OE is LOW, the latch outputs are in the high impedance OFF-state. OE does not affect the state of the latch. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VDD.

Features and benefits

  • Wide supply voltage range from 3.0 to 15.0 V

  • CMOS low power dissipation

  • High noise immunity

  • Fully static operation

  • 5 V, 10 V, and 15 V parametric ratings

  • Standardized symmetrical output characteristics

  • Complies with JEDEC standard JESD 13-B

  • ESD protection:

    • HBM JESD22-A114F exceeds 2000 V

    • MM JESD22-A115-A exceeds 200 V (C = 200 pF, R = 0 Ω)

  • Specified from -40 °C to +85 °C

Applications

  • Four-bit storage with output enable
