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.
