HEF4040B - 12-stage binary ripple counter

General Description

The HEF4040B is a 12-stage binary ripple counter with a clock input (CP), an overriding asynchronous master reset input (MR) and twelve fully buffered outputs (Q0 to Q11).

The counter advances on the HIGH-to-LOW transition of CP.

Key Features

  • Tolerant of slow clock rise and fall time.
  • Fully static operation.
  • 5 V, 10 V, and 15 V parametric ratings.
  • Standardized symmetrical output characteristics.
  • Specified from 40 C to +85 C.
  • Complies with JEDEC standard JESD 13-B 3.

HEF4040B 12-stage binary ripple counter Rev. 9 — 23 March 2016 Product data sheet 1. General description The HEF4040B is a 12-stage binary ripple counter with a clock input (CP), an overriding asynchronous master reset input (MR) and twelve fully buffered outputs (Q0 to Q11). The counter advances on the HIGH-to-LOW transition of CP. A HIGH on MR clears all counter stages and forces all outputs LOW, independent of CP. Each counter stage is a static toggle flip-flop. The clock input is highly tolerant of slow rise and fall times due to its Schmitt trigger action. It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input. 2.
