SN74ALS163BNSR

Counter Dividers Overview

The SN74ALS163BNSR is a synchronous 4-bit binary counter from the Texas Instruments ALS logic family, housed in a 16-pin SOIC surface-mount package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an up-counting sequence with synchronous parallel load and asynchronous clear functions. The device features three-state outputs for bus-driven applications and is rated for operation between 0°C and +70°C.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting with parallel data loading capability
• Asynchronous master reset for immediate clearing of all flip-flops
• Three-state outputs designed for direct bus interface connections

Counter Dividers Applications

• Digital timing and sequencing circuits
• Frequency division networks
• Event counting systems

Counter Dividers Procurement Notes

Verify the specific suffix against official documentation to confirm pinout compatibility and electrical characteristics. Ensure the component meets required environmental standards for the intended deployment environment before finalizing procurement decisions.

Counter Dividers Selection Notes

Select this component when synchronous control and high-speed performance are required. The ALS series offers improved speed-power product compared to standard TTL. Verify that the system design accommodates the specific power supply requirements and thermal constraints associated with the SOIC-16 package.

Counter Dividers Part Context

This part belongs to the SN74ALS163B family of synchronous counters. It shares functional similarities with other members like the SN74ALS161 but differs in reset mechanisms. The 'B' suffix typically denotes specific speed grades or manufacturing revisions within the ALS series.

Counter Dividers Replacement Considerations

SN74ALS163BN is a verified PDIP equivalent offering identical functionality in a through-hole package.
