HEF4543BT Datasheet Bcd To 7-segment Latch/decoder/driver

Manufacturer: Nexperia

Overview: HEF4543B BCD to 7-segment latch/decoder/driver Rev. 9 — 15 August 2024 Product data sheet 1.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The HEF4543B is a BCD to 7-segment latch/decoder/driver for liquid crystal and LED displays.

It has four address inputs (D0 to D3), an active LOW latch enable input (LE), an active HIGH blanking input (BL), an active HIGH phase input (PH) and seven buffered segment outputs (Qa to Qg).

The circuit provides the function of a 4-bit storage latch and an 8-4-2-1 BCD to 7-segment decoder/driver.

Key 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.
