CD74HC190PW

Counter Dividers Overview

The CD74HC190PW is a synchronous up/down decade counter manufactured by Texas Instruments. It operates within the HC logic family and features a wide supply voltage range of 2 V to 6 V. The device supports bidirectional counting with a parallel load capability and includes a ripple clock output for cascading applications. It is housed in a 16-pin TSSOP package and functions reliably across an extended temperature range from -55 °C to +125 °C.

Counter Dividers Feature Summary

• Synchronous up/down decade counting functionality
• Parallel load capability for data input
• Ripple clock output for multi-stage expansion

Counter Dividers Applications

• Digital timing sequences
• Frequency division circuits
• Counting systems requiring decade modulus

Counter Dividers Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure operating conditions remain within the specified voltage and temperature limits for reliable performance.

Counter Dividers Selection Notes

Select this component for designs requiring synchronous decade counting with bidirectional control. It serves as a suitable alternative to older logic families while maintaining compatibility with standard CMOS interfaces. Consider the TSSOP package constraints for PCB layout requirements.

Counter Dividers Part Context

This part belongs to the Texas Instruments 74HC series, which utilizes silicon gate CMOS technology. The series offers high-speed operation comparable to LSTTL but with significantly lower power consumption. The CD74HC190 specifically addresses applications needing precise decimal counting operations.
