MM74HC4040M

The MM74HC4040M from Texas Instruments is a 12-stage high-speed CMOS binary ripple counter. This integrated circuit utilizes advanced silicon-gate CMOS technology to achieve speed performance comparable to LS-TTL logic while maintaining low power consumption and high noise immunity.

Key electrical characteristics include an operating supply voltage range of 2V to 6V and a maximum clock speed of 35MHz. The counter advances one count on the negative clock transition of each input pulse. A common reset line allows all counters to be reset to their zero state with a high voltage level. All inputs and outputs are buffered for robust operation.

This component is housed in a 16-pin SOIC package and is designed for surface mounting. Its design offers balanced propagation delay and transition times, making it suitable for various digital logic applications requiring precise counting and timing.

Features include fully static operation, common reset functionality, and negative edge pulsing. It offers direct LSTTL input logic compatibility and CMOS input compatibility, with standard outputs rated for 10 LSTTL loads and bus driver outputs for 15 LSTTL loads. The MM74HC4040M is a green product.
