CD40103BF

Counter Dividers Overview

The CD40103BF is a CMOS 8-stage presettable synchronous down counter manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55 °C to +125 °C. The device features asynchronous and synchronous preset capabilities, along with ripple clock inputs for cascading applications. It is housed in a 16-lead hermetic dual-in-line ceramic package (CDIP) with a J-style lead configuration.

Counter Dividers Feature Summary

• Synchronous counting architecture utilizing a ripple clock input mechanism
• Dual-mode preset functionality supporting both asynchronous and synchronous loading
• Hermetic packaging designed for high-reliability environments

Counter Dividers Applications

• Military and defense electronic systems requiring radiation-hardened or sealed components
• High-reliability industrial control equipment
• Aerospace instrumentation and avionics subsystems

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'F' confirms the hermetic ceramic package variant rather than standard plastic packages. Confirm RoHS compliance status as the datasheet indicates this specific package option may not be RoHS compliant. Ensure the procurement channel provides traceability documentation required for military-grade hardware acquisition.

Counter Dividers Selection Notes

Select this component when hermetic sealing is mandatory for environmental protection or reliability standards. Compare against the plastic DIP (E suffix) or SOIC (NSR suffix) variants if hermeticity is not required. Verify that the 16-pin CDIP footprint matches the target PCB design constraints and assembly capabilities.

Counter Dividers Part Context

This part belongs to the CD4000B series of CMOS logic devices produced by Texas Instruments. It functions as an 8-bit binary counter capable of decrementing counts synchronously. The family includes related models such as the CD40102B, which offers similar functionality but lacks the preset feature found in the CD40103B.

Counter Dividers Replacement Considerations

Qualified versions include the catalog version CD40103B and the military-certified CD40103B-MIL. Other package options like CD40103BE or CD40103BNSR provide identical electrical performance but utilize non-hermetic plastic housings.
