SN74HC193NG4

Counter Dividers Overview

The SN74HC193NG4 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 provides independent UP and DOWN clock inputs.

Counter Dividers Feature Summary

• Synchronous operation eliminates output counting spikes associated with asynchronous counters
• Parallel asynchronous load allows programmable modulo-N count lengths
• Asynchronous clear input forces all outputs low independently of other functions
• Look-ahead circuitry enables easy cascading via dedicated carry and borrow outputs

Counter Dividers Applications

• Binary counting sequences in digital systems
• Modulo-N frequency division circuits
• Cascaded multi-stage counter designs
• Programmable timing control applications

Counter Dividers Procurement Notes

Verify the specific package type and manufacturer part number against official Texas Instruments documentation before procurement. Confirm that the ordering suffix matches the required pin configuration and environmental specifications. Ensure compatibility with system voltage levels and temperature ranges defined in the datasheet.

Counter Dividers Selection Notes

Select this component when synchronous bidirectional counting is required within the HC logic family constraints. Consider the 2 V to 6 V supply range and industrial temperature limits. Evaluate the need for parallel loading and cascading features inherent to the design.

Counter Dividers Part Context

This device belongs to the SN74HC193 series of 4-bit synchronous reversible counters. It is part of the broader 74HC logic family designed for high-speed CMOS applications. The 'N' suffix typically denotes a PDIP package variant, though verification with the specific datasheet is necessary.

Counter Dividers Replacement Considerations

SN74HC193N is a direct equivalent within the same series. SN74HC193DR offers the same functionality in a SOIC package. SN74HC193PWR provides the function in a TSSOP package.
