STMicroelectronics, Inc. Counters, Dividers M74HC4040TTR

The M74HC4040TTR is a high-speed CMOS 12-stage binary counter designed for efficient counting applications. It operates with a maximum frequency of 70 MHz at a supply voltage of 6V and features low power dissipation, drawing a maximum of 4 mA at 25¬8C. The device has a wide operating voltage range from 2V to 6V and offers high noise immunity with a minimum noise margin of 28% of VCC. This counter includes a clear input for resetting the counter to a low state and increments the count on the rising edge of the clock input. Each division stage provides an output, allowing for a final frequency output of 1/4096 of the input frequency. The M74HC4040TTR is pin and function compatible with the 74 series 4040, making it suitable for various applications where a binary counting function is required. Additionally, it is equipped with protection circuits against static discharge and transient voltage, enhancing its reliability in different environments.
