HD74LS193P (74LS193)
Description:
The HD74LS193P is a high-speed 4-bit synchronous binary up/down counter IC. It operates synchronously, meaning that all internal operations are synchronized to a clock signal. This counter can count up or down depending on the state of the control inputs. It features a parallel load capability for loading data into the counter asynchronously. The HD74LS193P is commonly used in digital systems for applications requiring counting sequences, frequency division, time measurement, and other similar functions.
