Working Principles

The 74HC393PW,112 is a dual 4-bit binary ripple counter. It consists of two separate counters, each with its own clock input (CP1 and CP2). The counters increment on the rising edge of the clock signal. The outputs (Q0-Q3 and Q4-Q7) represent the current count value in binary format.

The counters can be reset to zero using the master reset input (MR), which is asynchronous and independent for both counters. When MR is activated, all outputs are forced to zero.

Detailed Application Field Plans

• Frequency division: The 74HC393PW,112 can be used to divide an input clock frequency by various factors, depending on the desired output frequency.
• Event counting: It can be employed to count events or pulses occurring at the clock inputs, providing a digital representation of the number of occurrences.
• Timekeeping: By connecting an appropriate clock source, the IC can be utilized as a basic timekeeping component in applications that require simple timing functions.

Detailed and Complete Alternative Models

• CD40193: Similar functionality but operates at higher voltage levels (up to 18V)
• SN74LS393: Compatible with TTL logic levels, suitable for mixed logic systems
