The 74HC4040D from Philips is a high-speed, 12-stage binary ripple counter. It is pin-compatible with the HEF4040B series and specified in compliance with JEDEC standard no. 7A.
This counter 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 characteristics include propagation delays as low as 8 ns (Qn to Qn+1) and a maximum operating frequency of up to 90 MHz at 5V VCC and 15 pF load capacitance. The device operates over a temperature range of -40°C to +125°C.
Available in a SO16 package, the 74HC4040D is suitable for applications such as frequency dividing circuits, time delay circuits, and control counters.
