SN54HC191TDE2

Counter Dividers Overview

The SN54HC191TDE2 is a High Speed CMOS logic device from Texas Instruments, classified as a presettable synchronous 4-bit binary up/down counter. It operates within the 54HC series and features positive edge triggering for its flip-flops. The component supports asynchronous reset functionality and allows for both up and down counting directions. Designed for military-grade reliability, it utilizes die packaging without leads. The device is engineered to function across a specified temperature range of 0°C to +25°C, ensuring stable performance in demanding environments.

Counter Dividers Feature Summary

• Synchronous 4-bit binary up/down counting capability with presettable inputs
• Positive edge-triggered operation for precise timing control
• Asynchronous reset mechanism for immediate state clearing
• High-speed CMOS technology optimized for low power consumption

Counter Dividers Applications

• Military-grade digital signal processing systems requiring reliable binary counting
• Precision timing circuits utilizing synchronous up/down operations
• Embedded control units needing presettable counter functions
• Automated test equipment requiring high-speed binary division

Counter Dividers Procurement Notes

Verify the specific lot code and manufacturing date against project requirements due to potential lifecycle variations. Confirm that the die package format aligns with your assembly capabilities, as standard leaded packages are not applicable. Ensure thermal management strategies account for the restricted operating temperature range of 0°C to +25°C during system integration and validation phases.

Counter Dividers Selection Notes

Select this component when military-grade reliability and synchronous up/down counting are required. It is suitable for applications where space constraints necessitate die-level integration rather than traditional packages. Consider the limited operating temperature range carefully; if wider thermal tolerance is needed, alternative commercial grade variants may be more appropriate for general industrial use.

Counter Dividers Part Context

This part belongs to the SN54HC191 family of synchronous binary counters. It shares functional similarities with the SN74HC191 but differs in packaging and environmental specifications. The 'TDE' suffix indicates a bare die configuration, distinguishing it from surface-mount or through-hole equivalents like the NS or D variants found in commercial product lines.
