SN74HC193PWT

Counter Dividers Overview

The SN74HC193PWT is a 4-bit synchronous reversible up/down binary counter manufactured by Texas Instruments. It operates within 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 asynchronous clear, parallel asynchronous load for modulo-N count lengths, and look-ahead circuitry for cascading. It utilizes a 16-pin TSSOP package with a standard packing quantity of 250 units per tube.

Counter Dividers Feature Summary

• Synchronous operation eliminates output counting spikes associated with asynchronous counters
• Parallel asynchronous load capability allows modification of count length for modulo-N dividers
• Look-ahead circuitry enables easy cascading without external logic
• Asynchronous clear input forces all outputs low independently of other inputs

Counter Dividers Applications

• Modulo-N frequency division circuits
• Cascaded multi-stage binary counting systems
• Digital timing and sequence control applications

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'T' corresponds to the tube packaging configuration as indicated in the manufacturer's documentation. Confirm that the component meets the required industrial temperature specifications (-40°C to 85°C) for the intended application environment. Ensure compatibility with the 16-pin TSSOP footprint during PCB layout verification.

Counter Dividers Selection Notes

Select this component when synchronous counting behavior is required to prevent ripple-clock glitches. The dual clock inputs (UP/DOWN) allow independent direction control. Consider the HC logic family characteristics regarding power consumption and drive capability relative to the connected loads. Verify voltage levels match the system requirements across the full operating temperature range.

Counter Dividers Part Context

This part belongs to the SN74HC193 series of 4-bit synchronous reversible counters. It shares functional similarities with other members of the 74HC logic family but is distinguished by its specific pinout and package type. The device is designed for general-purpose digital counting tasks requiring precise synchronization and flexible preset capabilities.

Counter Dividers Replacement Considerations

SN74HC193PWR serves as a direct alternative offering identical functionality in a tape-and-reel format.
