- Synchronous presettable 4-bit binary up counter with TCO carry-out output for cascading multiple stages
- Asynchronous reset input provides immediate counter clear independent of the clock signal
- AC logic family supports 50 pF load capacitance with fast switching speeds in a 16-pin SOIC package
What is CD74AC161M96 used for?
The CD74AC161M96 is used in digital timing circuits, frequency dividers, and event counters in industrial control and communications equipment. Its synchronous preset capability enables the counter to be initialized to any 4-bit value on demand, making it suitable for programmable sequence generation and clock division chains. Multiple devices can be cascaded using the TCO output to build wider counters for address generation and state machine applications.

Frequently Asked Questions
How can multiple CD74AC161M96 devices be cascaded to build a wider binary counter?
The CD74AC161M96 provides a TCO (terminal count output) carry-out signal that goes high when the counter reaches its maximum count of 15. Connecting the TCO of one device to the enable input of the next creates a ripple-carry chain, allowing designers to build 8-bit, 12-bit, or wider synchronous binary counters using multiple 4-bit stages with minimal external logic.
What is the difference between synchronous preset and asynchronous reset on CD74AC161M96?
The CD74AC161M96 features synchronous parallel load that transfers the 4-bit preset input to the counter output on the next rising clock edge, enabling precise timing of counter initialization. The asynchronous reset clears all 4 output bits to zero immediately when asserted, independent of the clock, providing a fast emergency stop function without waiting for the next clock cycle.
Which supply voltage range does CD74AC161M96 support for mixed-voltage system designs?
The CD74AC161M96 belongs to the AC logic family and operates over a 2 V to 5.5 V supply voltage range, supporting both 3.3 V and 5 V system designs. With a 50 pF load capacitance rating, the device drives standard PCB trace capacitances at high clock rates, making it compatible with modern mixed-voltage embedded systems and FPGA interface boards.
In what PCB footprint does CD74AC161M96 ship and how does this affect assembly?
The CD74AC161M96 comes in a 16-pin SOIC (Small Outline IC) package with a standard 1.27 mm pitch, compatible with automated SMT assembly lines and widely available pick-and-place tooling. The SOIC package dimensions are approximately 9.9 mm x 3.9 mm, offering a compact footprint suitable for high-density digital logic boards requiring counter and timer functions.
