CD74HC192PWT

Counter Dividers Overview

The CD74HC192PWT is a high-speed CMOS logic presettable synchronous BCD decade up/down counter manufactured by Texas Instruments. It features asynchronous reset and operates within a supply voltage range of 2 V to 6 V. The device supports bidirectional counting with separate up and down clock inputs, providing TCO UP and TCO DOWN outputs for cascading applications. It is housed in a 16-TSSOP package and is rated for an operating temperature range of -55°C to 125°C.

Counter Dividers Feature Summary

• Synchronous BCD decade counting capability with presettable input functionality
• Bidirectional operation utilizing separate dedicated up and down clock inputs
• Asynchronous reset mechanism for immediate state initialization
• High-speed CMOS technology ensuring low power consumption and wide voltage tolerance

Counter Dividers Applications

• Digital frequency division circuits
• Time-base generation systems
• Cascaded multi-digit decimal counters
• Programmable timing control units

Counter Dividers Procurement Notes

Verify the specific suffix 'PWT' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and moisture sensitivity level. Ensure the component meets RoHS3 compliance requirements as specified in the latest production change notices. Cross-reference the ordering information with authorized distributors to validate current availability status and lead times.

Counter Dividers Selection Notes

Select this component when a synchronous BCD decade counter with independent up/down control is required. The HC series offers compatibility with standard 5V logic levels while supporting lower voltages down to 2V. Consider the TSSOP-16 package constraints for PCB layout and thermal management. Verify that the asynchronous reset requirement aligns with the system's startup sequence needs.

Counter Dividers Part Context

This part belongs to the Texas Instruments 74HC family of high-speed CMOS logic devices. The 74HC192 specifically addresses applications requiring precise decimal counting with parallel load capabilities. It serves as a fundamental building block in digital electronics for sequential logic operations, distinct from binary counters like the 74HC193 which lack the BCD decoding output structure.

Counter Dividers Replacement Considerations

The CD74HC192PWRE4 is a verified equivalent part number offering identical electrical characteristics and pinout compatibility. Both variants function as synchronous BCD decade up/down counters within the same logic family specifications.
