Working Principles

The 74HC193DB,112 is a binary synchronous counter with an asynchronous reset. It operates by counting the number of clock pulses received on the CP input. The counter advances one stage on each clock pulse, and the output pins (QA-QD) represent the current count value. The master reset input (MR) allows for resetting the counter to its initial state asynchronously.

Detailed Application Field Plans

• Frequency division: The 74HC193DB,112 can be used to divide an input clock frequency by a specific factor.
• Event counting: It can be employed to count the occurrence of events in various applications.
• Timekeeping: The counter can be utilized in timekeeping circuits to measure elapsed time.

Detailed and Complete Alternative Models

• 74HC190: Similar to 74HC193DB,112 but without the asynchronous reset feature.
• CD40193: A CMOS version of the binary synchronous counter with asynchronous reset.
