Frequently Asked Questions
What is the CD74AC163E and what are its key specifications?
The CD74AC163E is a 4-stage synchronous binary counter from Texas Instruments. It features up-counting operation, a load/preset input, and TCO (Terminal Count Output). It operates from a 1.5V to 5.5V supply voltage with a 50pF load capacitance, and is housed in a 16-Pin PDIP (Dual-In-Line) package.
What applications is the CD74AC163E suitable for?
The CD74AC163E is well-suited for digital counting and sequencing applications including frequency dividers, event counters, address generators, and state machines. Its synchronous operation and preset capability make it ideal for use in digital logic systems, embedded control circuits, and timing circuits where deterministic counting behavior is required.
How does the synchronous load/preset feature of the CD74AC163E work?
The CD74AC163E provides a synchronous load/preset input that allows the counter to be loaded with a specific binary value on the next rising clock edge when asserted. This enables the counter to start from a user-defined value rather than zero, which is useful for creating custom counting sequences or implementing modulo-N counters in digital designs.
