SN74HC193PW

Counter Dividers Overview

The SN74HC193PW 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 fully synchronous counting, asynchronous clear, and parallel asynchronous load capabilities. It utilizes a 16-pin TSSOP package.

Counter Dividers Feature Summary

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

Counter Dividers Applications

• Modulo-N dividers
• Cascaded counter systems
• Binary counting sequences
• Reversible frequency division

Counter Dividers Procurement Notes

Verify the specific ordering suffix against current TI documentation to confirm package type and status. Confirm RoHS compliance and lead finish details via the official datasheet or package addendum before procurement. Ensure design compatibility with recommended operating conditions.

Counter Dividers Selection Notes

Select this component for applications requiring synchronous bidirectional counting in CMOS technology. Verify that the 16-pin TSSOP package fits the PCB layout constraints. Ensure the operating voltage and temperature ranges align with system requirements.

Counter Dividers Part Context

This part belongs to the SN74HC193 family of 4-bit synchronous reversible counters. It is designed for high-speed digital counting applications where synchronous clocking is required to prevent ripple effects. The HC series offers low power consumption and wide voltage operation.

Counter Dividers Replacement Considerations

SN74HC193PWR is an active production alternative in the same TSSOP-16 package. Other variants include SN74HC193DR (SOIC) and SN74HC193NSR (SOP). Verify pinout and electrical characteristics match application needs.
