SNJ54HC393FK

Counter Dividers Overview

The SNJ54HC393FK is a military-grade dual 4-bit binary counter from Texas Instruments, housed in a 20-pin LCCC package. It operates within a supply voltage range of 2V to 6V and supports an operating temperature range of -55°C to 125°C. The device integrates two independent counters with individual clocks and direct clear inputs. Key electrical specifications include a maximum ICC of 80μA at 6V, typical propagation delay (tpd) of 13ns, and output drive capabilities of ±4mA at 5V.

Counter Dividers Feature Summary

• Integrates two independent 4-bit binary counters within a single package
• Features direct clear inputs for each counter stage
• Provides parallel outputs from all flip-flop stages
• Supports wide operating voltage range from 2V to 6V

Counter Dividers Applications

• Military and defense electronic systems
• High-density digital timing circuits
• Frequency division applications
• Binary counting sequences

Counter Dividers Procurement Notes

Verify the specific ordering suffix FK corresponds to the 20-pin LCCC package configuration. Confirm that the SNJ prefix indicates QML certification requirements are met for the intended application environment. Ensure compatibility with existing board layouts designed for ceramic leadless chip carriers.

Counter Dividers Selection Notes

Select this component when military-grade reliability and extended temperature operation are required. The dual-counter architecture reduces overall package count compared to using separate single counters. Verify that the 20-pin LCCC footprint matches the target PCB design constraints.

Counter Dividers Part Context

This part belongs to the SN54HC393 family, which includes variants in CDIP and CFP packages. The SNJ54HC393FK specifically denotes the military version in the LCCC form factor. It shares functional equivalence with other HC series counters but offers distinct packaging characteristics suitable for specialized mounting requirements.
