Overview
The HEF4040BT-Q100118 is a 12-stage binary ripple counter produced by NXP USA Inc., now part of Nexperia. This integrated circuit features a clock input (CP) and an overriding asynchronous master reset input (MR), along with twelve fully buffered outputs (Q0 to Q11). The counter advances on the HIGH-to-LOW transition of the clock input. A HIGH on the master reset input clears all counter stages and forces all outputs LOW, independent of the clock input. Each counter stage is a static toggle flip-flop.
This device is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 3), making it suitable for use in automotive applications. It operates over a wide supply voltage range from 3.0 V to 15.0 V and is specified from -40 °C to +85 °C.
