93L10FMQB

Counter Dividers Overview

The National Semiconductor 93L10FMQB is a high-speed 4-bit magnitude comparator belonging to the 93L series. It features TTL-compatible inputs and true outputs, designed for applications requiring rapid digital comparison. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an extended industrial temperature range from -55 °C to 125 °C. Packaged in a ceramic flatpack (CDFP16), it offers a propagation delay of 35 ns. The component includes an active-low inhibit input to control output states.

Counter Dividers Feature Summary

• Provides parallel comparison of two 4-bit binary words to determine relative magnitude relationships.
• Features TTL-compatible logic levels with true output polarity for direct interfacing.

Counter Dividers Applications

• High-speed digital data processing systems
• Address decoding circuits
• Control logic for arithmetic units

Counter Dividers Procurement Notes

Verify the manufacturer designation as Rochester Electronics, which handles distribution for legacy components originally produced by National Semiconductor. Confirm the package type is CDFP16 ceramic flatpack and ensure compliance with MIL-STD-883 Class B screening requirements if specified for your application. Check for any specific ordering suffixes that may indicate testing or burn-in levels.

Counter Dividers Selection Notes

Select this component when a 4-bit magnitude comparison function is required with TTL compatibility and high speed. The 93L series offers faster performance than standard LS counterparts. Ensure the system design accommodates the 16-pin ceramic flatpack footprint and operates within the specified 4.5 V to 5.5 V supply range.

Counter Dividers Part Context

The 93L10 is part of the 93L family of high-speed logic devices. This series was designed to provide improved switching speeds over standard logic families while maintaining TTL compatibility. The FMQB suffix typically denotes a military-grade or screened version of the standard 93L10 device, packaged in a durable ceramic flatcase suitable for harsh environments.

Counter Dividers Replacement Considerations

Direct pin-to-pin replacements include the National Semiconductor 93L10N or equivalent parts from other manufacturers offering 4-bit comparators in a 16-pin DIP or flatpack. Verify that substitute components meet the same propagation delay and temperature range specifications.
