SN74LS163ANE4

Counter Dividers Overview

The SN74LS163ANE4 is a synchronous 4-bit binary counter from the Texas Instruments SN54/74LS163A series. It features a positive-edge-triggered clock input and operates within a supply voltage range of 4.75 V to 5.25 V. The device supports synchronous presetting and synchronous clearing functions, allowing data loading or resetting without affecting the clock signal. It is housed in a 16-pin PDIP package with through-hole mounting capabilities.

Counter Dividers Feature Summary

• Synchronous four-bit binary counting operation triggered by positive clock edges
• Independent synchronous preset and clear control inputs for non-clock-dependent state management
• Carry output generation for cascading multiple counters into larger modulus configurations

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generators for digital clocks
• Event sequence counters in industrial automation

Counter Dividers Procurement Notes

Verify component authenticity against official Texas Instruments documentation before integration. Confirm that the specific ordering suffix matches the required package type and lead finish specifications. Ensure compliance with RoHS directives as indicated in the manufacturer's packaging information. Validate operational temperature ranges against system environmental requirements.

Counter Dividers Selection Notes

Select this component when synchronous reset functionality is required to avoid glitches associated with asynchronous methods. The LS logic family provides standard TTL compatibility suitable for general-purpose digital systems. Consider alternative packages such as SOIC or SOP if surface-mount technology is preferred over through-hole installation.

Counter Dividers Part Context

This part belongs to the SN54/74LS163A family of synchronous 4-bit counters. It shares functional characteristics with other members like the SN74LS161AN but differs in specific control logic implementations. The 'E4' suffix denotes a specific manufacturing revision compliant with current environmental standards.
