M74HC192RM13TR

Counter Dividers Overview

The M74HC192RM13TR is a high-speed CMOS synchronous up/down decade counter fabricated with silicon gate C2MOS technology. It features two separate clock inputs for independent up and down counting, triggered on the low-to-high transition of either clock while the other is held high. The device includes asynchronous parallel load via an active-low LOAD input, allowing data entry on DATA A through D inputs to modify count length or function as divide-by-n counters. An active-high CLEAR input resets all four internal stages to low. Cascading is supported by dedicated active-low CARRY and BORROW outputs that pulse on overflow and underflow respectively.

Counter Dividers Feature Summary

• Synchronous up/down decade counting capability with dual independent clock inputs
• Asynchronous parallel preset functionality for flexible count modification
• Dedicated carry and borrow outputs enable seamless cascading of multiple units

Counter Dividers Applications

• Digital frequency division circuits
• Cascaded multi-digit decimal counting systems
• Programmable timing and sequence generation logic

Counter Dividers Procurement Notes

Verify component authenticity against STMicroelectronics official documentation due to obsolete status. Confirm package integrity and pin alignment prior to integration. Review datasheet specifications for absolute maximum ratings and operating conditions to ensure compatibility with target system voltage and temperature ranges.

Counter Dividers Selection Notes

Select this component for applications requiring precise synchronous decade counting with independent direction control. Ensure supply voltage remains within the specified 2V to 6V range. Verify that input signal rise and fall times comply with recommended operating conditions to maintain noise immunity and propagation delay performance.

Counter Dividers Part Context

This part belongs to the M74HC192 series of synchronous up/down decade counters. It is pin and function compatible with the standard 74 series 192. The RM13 suffix indicates surface mount packaging in SO-16 format. The device utilizes C2MOS technology for high speed and low power dissipation characteristics typical of the HC logic family.

Counter Dividers Replacement Considerations

Direct substitutes include M74HC192B1R (DIP) and M74HC192M1R (SOIC). Cross-vendor equivalents such as SN74HC192 are functionally compatible but require verification of electrical parameters.
