Counter Dividers datasheet and documents for CD54HCT393F

CD54HCT393F

Counter Dividers Overview

The CD54HCT393F is a high-speed CMOS logic dual 4-stage binary counter manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features negative-edge clocking with a common reset line that forces all counters to zero. The device utilizes buffered inputs and outputs, providing direct LSTTL input logic compatibility. It is housed in a hermetically sealed ceramic dual in-line package (CDIP) with 14 pins, designed for operation across an extended temperature range from -55°C to 125°C.

Counter Dividers Feature Summary

Dual independent 4-bit binary ripple-carry counters
Negative-edge triggered state advancement
Common master reset functionality
Buffered inputs and outputs

Counter Dividers Applications

Military and defense digital counting systems
High-reliability industrial timing circuits
Avionics data processing modules
Space-qualified telemetry counters

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'F' corresponds to the standard CDIP package configuration. Confirm RoHS exemption status as military-grade variants often differ from commercial standards. Ensure the supplier provides traceability documentation required for defense applications. Validate that the component meets QML certification requirements if specified for the target system.

Counter Dividers Selection Notes

Select this component when direct LSTTL interface compatibility is required alongside high-speed CMOS performance. The HCT series ensures proper logic level translation without external buffering. Choose the CD54 prefix for extended temperature ranges and hermetic sealing necessary for harsh environments compared to the commercial 74 series alternatives.

Counter Dividers Part Context

This part belongs to the CDx4HCT393 family of dual 4-bit binary counters. It shares functional characteristics with the CD54HC393 but differs in electrical specifications to support 5 V logic systems. The CD54 designation indicates qualification for military and aerospace environments, distinguishing it from the commercial CD74 series which lacks hermetic packaging.
