CD54HC393F3A

Counter Dividers Overview

The CD54HC393F3A is a high-speed CMOS logic dual 4-stage binary counter manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an extended temperature range from -55°C to 125°C. The device features fully static operation, buffered inputs, and negative-edge clocking with a common reset line. It utilizes a 14-pin Ceramic Dual In-Line Package (CDIP) with dimensions of 19.55 mm by 6.71 mm.

Counter Dividers Feature Summary

• Dual independent 4-stage ripple-carry binary counters
• Negative-edge triggered flip-flops for state advancement
• Common master reset input for zero-state initialization
• Buffered inputs and outputs for signal integrity

Counter Dividers Applications

• Military and defense digital counting systems
• High-reliability frequency division circuits
• Industrial control timing sequences
• Avionics data processing counters

Counter Dividers Procurement Notes

Verify the specific ordering suffix F3A corresponds to the required military-grade ceramic package configuration. Confirm RoHS exemption status as indicated in the packaging addendum. Ensure procurement channels provide traceability documentation suitable for defense or aerospace qualification requirements.

Counter Dividers Selection Notes

Select this component when military-grade environmental resilience and hermetic sealing are mandatory. The HC series offers wide voltage flexibility compared to HCT variants. Verify that the 14-pin CDIP footprint matches the target PCB layout constraints and thermal management strategy.

Counter Dividers Part Context

This part belongs to the Texas Instruments 54HCT/HC family of high-speed CMOS logic devices. The '54' prefix designates military-grade specifications, distinguishing it from commercial '74' series parts. It shares functional compatibility with other dual 4-bit counters in the same logic family while providing enhanced reliability standards.

Counter Dividers Replacement Considerations

Direct substitutes include CD54HC393F and CD54HCT393F. Catalog equivalents such as CD74HC393E offer similar functionality but lack the military-grade ceramic construction.
