Working Principles

CD74HC193MG4 operates based on synchronous binary up/down counting principles. The clock input (CLK) triggers the counting operation, while the master reset input (MR) asynchronously resets the counter to its initial state. The count enable parallel input (CPD) and count enable input (CTEN) control the counting direction and enable/disable the counting operation, respectively. The data input (D) allows for parallel loading of a specific count value. The outputs (Q0-Q3) provide the current count value, and the ripple carry output (RC) facilitates cascading multiple devices for larger count lengths.

Detailed Application Field Plans

CD74HC193MG4 finds applications in various digital electronic systems, including but not limited to: - Frequency dividers - Digital clocks - Industrial automation - Automotive electronics - Communication systems - Consumer electronics
