HEF4027BT - Dual JK flip-flop

Download the HEF4027BT datasheet PDF. This datasheet also covers the HEF4027B variant, as both devices belong to the same dual jk flip-flop family and are provided as variant models within a single manufacturer datasheet.

Description

The HEF4027B is a dual positive-edge triggered JK flip-flop featuring independent set direct (nSD), clear direct (nCD), clock inputs (nCP) and complementary outputs (nQ and nQ).

Data is accepted when nCP is LOW, and transferred to the output on the positive-going edge of the clock.

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.

HEF4027B Dual JK flip-flop Rev. 12 — 8 August 2024 Product data sheet 1. General description The HEF4027B is a dual positive-edge triggered JK flip-flop featuring independent set direct (nSD), clear direct (nCD), clock inputs (nCP) and complementary outputs (nQ and nQ). Data is accepted when nCP is LOW, and transferred to the output on the positive-going edge of the clock. The asynchronous clear-direct (nCD) and set-direct (nSD) are independent and override the nJ, nK, and nCP inputs. Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise and fall times. 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.
