The 74HC4040 CMOS 12-Stage Binary Counter is identical in pinout to the MC14040 standard CMOS. It consists of 12 master-slave flip-flops, where each flip-flop's output feeds the next, halving the frequency at each stage. The state counter advances on the negative-going edge of the Clock input. This device offers high noise immunity characteristic of CMOS devices and is compliant with JEDEC Standard No. 7A requirements.
Reset is asynchronous and active-high. Due to internal ripple delays, state changes in the Q outputs do not occur simultaneously, leading to decoding spikes in the output signals, which may need to be gated with the Clock of the HC4040A for certain designs.
The 74HC4040 is designed for versatile compatibility, with outputs that can directly interface with CMOS, NMOS, and TTL technologies. It offers a wide operating voltage range of 2.0 to 6.0V and low input current of 1A. With a chip complexity of 398 FETs or 99.5 equivalent gates, this device is suitable for various applications requiring unique control change requirements.
For automotive and specific applications, the NLV prefix denotes AEC-Q100 qualification and PPAP capability. Additionally, these devices are Pb-free, halogen-free, and RoHS compliant.
