Counter Dividers datasheet and documents for SN74AS163NS
Counter Dividers Overview
The SN74AS163NS is a synchronous 4-bit binary counter from the Texas Instruments AS series. It features positive-edge triggering and operates within a supply voltage range of 4.5 V to 5.5 V. The device supports synchronous preset and synchronous clear functions, allowing precise control over counting states without asynchronous interference. It is housed in a 16-pin plastic small-outline package (SOP-16) suitable for surface-mount applications. The component is designed for high-speed digital logic operations with defined propagation delays typical of the Advanced Schottky family.
Counter Dividers Feature Summary
- Synchronous 4-bit binary up-counter architecture with positive-edge clock triggering
- Supports synchronous parallel data loading via dedicated preset inputs
- Includes synchronous clear functionality for immediate state reset on command
- Operates reliably within standard 5V logic supply parameters
Counter Dividers Applications
- Digital frequency division circuits
- Timing sequence generation systems
- Event counting modules in industrial control panels
Counter Dividers Procurement Notes
Verify the specific suffix designation against official Texas Instruments documentation to confirm package type and temperature rating. Ensure the source provides valid RoHS compliance status and manufacturer traceability. Cross-reference the part number with current datasheets to confirm availability status and any recent design changes or obsolescence notices before finalizing procurement orders.
Counter Dividers Selection Notes
Select this component when high-speed synchronous counting is required within a 5V logic environment. The AS series offers faster switching speeds compared to standard TTL or HC families. Consider the SOP-16 package constraints for PCB layout. Verify that the application requires synchronous rather than asynchronous reset behavior to match the internal logic design.
Counter Dividers Part Context
This device belongs to the Texas Instruments SN74AS16x series of advanced Schottky logic counters. It shares functional compatibility with other 4-bit synchronous counters but distinguishes itself through superior speed characteristics inherent to the AS technology. It serves as a core timing element in complex digital systems requiring precise binary counting sequences.

Counter Dividers FAQ
Is the reset function asynchronous or synchronous?
The SN74AS163NS utilizes a synchronous clear function, meaning the reset action occurs only upon the active edge of the clock signal.
What is the trigger mechanism for the clock input?
The counter is triggered by the positive edge of the clock signal, advancing the count state on the rising transition.
