Working Principles

The 74HCT193PW,118 is a synchronous binary up/down counter that operates based on an external clock signal. It counts up or down depending on the input signals provided to the U/D (Up/Down) pin. The counter can be asynchronously reset using the MR (Master Reset) pin. The counting operation is synchronized with the clock signal provided at the CP (Clock Pulse) pin. The current count value is available at the four output pins QA, QB, QC, and QD.
