The SN74HC4040D is a 12-stage asynchronous binary counter from Texas Instruments' HC family. It counts on the high-to-low transition of the clock input and features an asynchronous clear function that resets all outputs low. The device is designed for a wide supply voltage range of 2V to 6V, making it suitable for battery-powered and low-voltage applications. With a maximum supply current of only 80µA and a typical propagation delay of 12ns, it offers low power consumption and moderate speed. Outputs can drive up to 10 LSTTL loads with ±4mA output drive at 5V. The input current is a maximum of 1µA. This counter is ideal for time-delay circuits, frequency division, and counter control applications. It comes in a 16-pin SOIC package with a body size of 9.90mm x 3.90mm, designed for surface mount assembly. The operating temperature range spans from -40°C to 85°C, suitable for industrial environments.
