74HC4040D Description

Short technical summary and product information.

The 74HC4040D from NXP Semiconductors is a high-speed Si-gate CMOS 12-stage binary ripple counter. It is pin-compatible with the HEF4040B series and specified in compliance with JEDEC standard no. 7A.

 

This counter IC features a clock input (CP) and an overriding asynchronous master reset input (MR). The counter advances on the HIGH-to-LOW transition of CP. A HIGH signal on the MR input clears all counter stages and forces all outputs LOW, regardless of the CP state. Each counter stage is a static toggle flip-flop.

 

Key electrical specifications include a typical propagation delay from CP to Q0 of 14 ns and from Qn to Qn+1 of 8 ns. The maximum operating frequency is typically 90 MHz under specified conditions. Input capacitance is 3.5 pF, and power dissipation capacitance is 20 pF.

 

The 74HC4040D is suitable for applications such as frequency dividing circuits, time delay circuits, and control counters. It is available in a plastic small outline package (SO16) and specified for operation over a temperature range of -40 °C to +125 °C.
