SN74ALS163BDRE4

Counter Dividers Overview

The SN74ALS163BDRE4 is a synchronous 4-bit binary counter from Texas Instruments' ALS logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports positive edge triggering. The device features parallel load capability, synchronous clear, and ripple clock outputs. It is housed in a 16-pin SOIC package with a tape and reel configuration.

Counter Dividers Feature Summary

• Synchronous 4-bit binary counting with up-counting direction
• Parallel data loading and synchronous clear functionality
• Ripple clock output for cascading applications

Counter Dividers Applications

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

Counter Dividers Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the SOIC-16 package type and tape-and-reel packaging format match system requirements. Ensure input voltage levels align with the specified 4.5 V to 5.5 V operating range for reliable ALS logic performance.

Counter Dividers Selection Notes

Select this component for designs requiring synchronous 4-bit binary counting with low power consumption typical of ALS technology. It is suitable where parallel loading and synchronous clearing are necessary. Compare against standard 74LS163 variants if higher speed or different drive capabilities are required.

Counter Dividers Part Context

This part belongs to the SN74ALS163B series of synchronous counters. It shares functional similarities with other 4-bit binary counters but utilizes Advanced Low-power Schottky (ALS) technology for improved speed-to-power efficiency compared to older LS families.

Counter Dividers Replacement Considerations

SN74ALS163BN is a PDIP-16 through-hole equivalent. SN74ALS169BDR is a similar ALS counter but supports up/down counting rather than fixed up-counting.
