HEF4894B - 12-stage shift-and-store register LED driver

Description

The HEF4894B is a 12-stage serial shift register.

It has a storage latch associated with each stage for strobing data from the serial input (D) to the parallel LED driver outputs (QP0 to QP11).

Data is shifted on positive-going clock (CP) transitions.

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.

HEF4894B 12-stage shift-and-store register LED driver Rev. 11 — 13 August 2024 Product data sheet 1. General description The HEF4894B is a 12-stage serial shift register. It has a storage latch associated with each stage for strobing data from the serial input (D) to the parallel LED driver outputs (QP0 to QP11). Data is shifted on positive-going clock (CP) transitions. The data in each shift register stage is transferred to the storage register when the strobe (STR) input is HIGH. Data in the storage register appears at the output whenever the output enable (OE) input signal is HIGH. Two serial outputs (QS1 and QS2) are available for cascading a number of HEF4894B devices.
