The CD74HC161MT is an integrated circuit (IC) component that belongs to the 74HC family of high-speed CMOS logic devices. It is a 4-bit synchronous binary counter with a presettable synchronous up/down feature. Here is an overview of its key features:
1. Binary counter: The CD74HC161MT can operate as a 4-bit binary counter, capable of counting from 0 to 15, depending on the clock input and control signals.
2. Synchronous operation: This IC has synchronous inputs and outputs, meaning that state changes occur simultaneously with the clock signal. This synchronous operation ensures reliable and predictable behavior during counting operations.
3. Up/down functionality: The CD74HC161MT offers presettable synchronous up/down functionality, allowing the counter to count up or down based on control inputs. By manipulating these inputs, the direction of counting can be easily controlled.
4. Asynchronous reset: The IC provides an asynchronous reset input that allows resetting the counter to zero regardless of the clock or control inputs. This feature ensures a straightforward means of restarting the counting process.
5. Schmitt-trigger inputs: The CD74HC161MT includes Schmitt-trigger inputs, which provide hysteresis and improve noise immunity. These inputs allow for reliable operation even in the presence of signal noise or fluctuations
