7492 Divide-by-12 Counter IC (74LS92) – 4-Bit Ripple Counter for Digital Clocks & Timing Circuits

Overview

The 7492 (74LS92) is a high-speed monolithic 4-bit ripple counter. It is internally partitioned into two sections: a divide-by-2 section and a divide-by-6 section. When these sections are combined, the IC functions as a highly efficient Divide-by-12 counter. This specific counting sequence is essential for any digital system that needs to track “dozens,” such as 12-hour time formats or specialized frequency oscillators.

Key Features

• Divide-by-12 Capability: Ideal for timekeeping applications where a 12-unit reset is required.

• Dual-Section Versatility: Can be used independently as a divide-by-2 and a divide-by-6 counter.

• Classic TTL Logic: Fully compatible with all 74-series logic gates and 5V microcontrollers like Arduino.

• Low Power Consumption: The LS (Low-power Schottky) version provides high speed with minimal power drain.

• Easy Prototyping: Comes in a standard 14-pin DIP package, fitting perfectly into breadboards and IC sockets.
