HEF4043BT - Quad R/S latch

Download the HEF4043BT datasheet PDF. This datasheet also covers the HEF4043B variant, as both devices belong to the same quad r/s latch family and are provided as variant models within a single manufacturer datasheet.

Description

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.

Features

  • Wide supply voltage range from 3.0 V 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: 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.

HEF4043B Quad R/S latch with 3-state outputs Rev. 14 — 3 September 2024 Product data sheet 1. General description 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. 2. Features and benefits • Wide supply voltage range from 3.0 V to 15.
