SN74HC193PWR

Counter Dividers Overview

The SN74HC193PWR is a 4-bit synchronous reversible up/down binary counter from the Texas Instruments HC logic family. It operates on a supply voltage range of 2 V to 6 V and supports an operating temperature range of -40°C to 85°C. The device features fully synchronous counting, asynchronous clear, and parallel asynchronous load capabilities. It includes look-ahead circuitry for cascading without external components and outputs capable of driving up to 10 LSTTL loads.

Counter Dividers Feature Summary

• Synchronous operation eliminates output counting spikes by clocking all flip-flops simultaneously
• Parallel asynchronous load allows presetting outputs to any binary value independently of count pulses
• Asynchronous clear input forces all outputs low regardless of other control signals
• Look-ahead circuitry enables direct cascading via dedicated carry and borrow outputs

Counter Dividers Applications

• Modulo-N counters using parallel load inputs
• Cascaded multi-stage binary counting systems
• Frequency division circuits
• Digital timing and sequencing applications

Counter Dividers Procurement Notes

Verify the specific ordering suffix matches the required package type and moisture sensitivity level. Confirm RoHS compliance status and lead finish specifications against current project requirements. Ensure the active production status aligns with long-term availability needs before finalizing procurement plans.

Counter Dividers Selection Notes

Select this component when synchronous bidirectional counting is required within standard industrial temperature limits. The HC series offers compatibility with standard CMOS logic levels. Verify that the 2 V to 6 V supply range meets system power constraints. Consider the TSSOP-16 package dimensions for PCB layout compatibility.

Counter Dividers Part Context

This part belongs to the SN74HC193 family of 4-bit synchronous reversible counters. It shares functional characteristics with other variants in the series but differs in packaging and thermal properties. The HC logic family provides high-speed operation with low power consumption compared to older logic standards.

Counter Dividers Replacement Considerations

SN74HC193DR serves as a parameter-equivalent alternative in the SOIC-16 package.
