The 74HC/HCT161 are presettable synchronous 4-bit binary counters with asynchronous reset. These devices are high speed silicon-gate CMOS devices that are pin compatible with low power Schottky TTL ...

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 ...

This document is a leaflet of NXP 74LVC169 demonstration board. This demonstration provides an easy evaluation of the 74LVC169, a binary counter with internal look-ahead carry circuitry designed for ...

The DS1372 real-time clock (RTC) integrates a binary counter and unique 64-bit serial number for digital data applications that require digital rights management (DRM). The binary counter allows easy ...

Makers, developers and hobbyists may be interested in a new interactive binary ruler that has been created by Bradley Slattery. The 15 cm ruler is equipped with seven logic gates, 4 x flip-flops and 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 ...
