Bats use echolocation to see objects in front of them. They emit an ultrasonic pulse around 20 kHz (and up to 100 kHz) and then sense the pulses as they reflect off an object and back to the bat. It’s ...

The 74LV393 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT393. The 74LV393 is a dual 4-bit binary ripple counter with separate clocks (1CP, 2CP) and master reset ...

The 74HC590 is a high-speed 8-bit binary counter with output register and 3-state outputs. This device features independent clock inputs in counter and register, master reset in counter, ESD ...

CISSOID is launching CHT-74-4040, a new member of its GALAXY digital product family. CHT-74-4040 is a 12-stage asynchronous binary counter, that can be used for instance as a frequency divider with a ...

We’ve seen a great many cat feeders over the years. Some rely on the Internet of Things, and some rely on fancy microcontrollers. [Larry Cook], on the other hand, built his using a simple 4060 binary ...
