The 74HC/HCT4040 is a high-speed 12-stage binary ripple counter with standard output capability and MSI category.
The document provides product specifications for the Philips 74HC/HCT4040 integrated circuit. This device is a high-speed Si-gate CMOS component that functions as a 12-stage binary ripple counter, featuring pin compatibility with the '4000B' series.
Key features include a clock input (CP) and an overriding asynchronous master reset input (MR). The counter advances on the HIGH-to-LOW transition of the clock signal. Each stage operates as a static toggle flip-flop, providing twelve parallel outputs ranging from Qo to Q11.
