MM54HCT192J

Counter Dividers Overview

The MM54HCT192J is a synchronous decade up/down counter manufactured by Rochester Electronics. It operates within the HCT logic series and features CMOS construction in a ceramic DIP-16 package. The device supports bidirectional counting with independent clock inputs for up and down operations. It includes dedicated carry/borrow outputs for cascading multiple counters. The component is designed for military-grade reliability, operating across an extended temperature range of -55°C to +125°C.

Counter Dividers Feature Summary

• Synchronous decade counting capability with separate up and down control inputs
• Bidirectional data flow management via distinct clock terminals
• Cascading support through dedicated carry and borrow output signals
• Military-grade ceramic packaging ensuring durability in harsh environments

Counter Dividers Applications

• Digital frequency division circuits
• Timekeeping and real-time clock modules
• Pulse sequence generation systems
• Industrial control logic sequencing

Counter Dividers Procurement Notes

Verify the manufacturer marking matches Rochester Electronics LLC specifications. Confirm the package type is ceramic DIP-16 and the suffix J indicates the correct variant. Check for date codes and lot traceability required for military or aerospace procurement standards. Ensure the component meets the specified HCT series electrical characteristics before integration.

Counter Dividers Selection Notes

Select this component when a synchronous decade counter with military temperature ratings is required. The HCT series ensures compatibility with standard TTL voltage levels while offering low power consumption. Consider the ceramic package for superior thermal stability compared to plastic variants. Verify that the bidirectional counting feature aligns with the system's direction control requirements.

Counter Dividers Part Context

This part belongs to the 54HCT family of digital logic components, which are designed for high-speed operation with CMOS power efficiency. The 54-series designation typically indicates military-grade qualification, distinguishing it from commercial 74-series equivalents. Rochester Electronics provides these parts as a continuous source for legacy and critical applications requiring long-term availability.

Counter Dividers Replacement Considerations

Direct substitutes include other 54HCT192 variants from different manufacturers if pin-compatible. Ensure replacement parts maintain the same ceramic DIP-16 package and military temperature rating. Verify that the substitute offers identical synchronous operation and decade counting functionality without altering the system timing constraints.
