CD40103BF3A

Counter Dividers Overview

The CD40103BF3A is a catalog-grade, 8-bit asynchronous binary down counter manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 15 V and supports an operating temperature range from -55 °C to 125 °C. The device features independent asynchronous reset and synchronous preset functions, allowing for flexible initialization. It is housed in a 16-lead hermetic dual-in-line ceramic package (CDIP) with J-leads.

Counter Dividers Feature Summary

• Provides eight cascaded flip-flops configured as an asynchronous binary down counter
• Includes independent asynchronous reset and synchronous parallel load capabilities
• Features high noise immunity suitable for harsh environments

Counter Dividers Applications

• Military and defense electronic systems requiring radiation-hardened or hermetic components
• Avionics timing and sequencing circuits
• Spacecraft telemetry and command logic modules

Counter Dividers Procurement Notes

Verify the specific ordering suffix F3A to confirm the hermetic ceramic package variant. Ensure that procurement channels are authorized to handle military-grade specifications. Confirm RoHS exemption status if required by system compliance standards. Validate lead finish material compatibility with assembly processes.

Counter Dividers Selection Notes

Select this component when hermetic sealing is mandatory for environmental protection. Compare against plastic variants like the CD40103BE if cost reduction is prioritized over hermeticity. Evaluate thermal management requirements given the wide operating temperature range. Consider pinout compatibility with existing PCB footprints designed for standard 16-pin DIP packages.

Counter Dividers Part Context

This part belongs to the CD4000B series of CMOS logic devices. It serves as a fundamental building block for digital counting applications. The B-series designation indicates standard catalog performance levels. Hermetic packaging distinguishes it from commercial plastic versions.

Counter Dividers FAQ

What type of reset mechanism does the CD40103BF3A utilize?

It utilizes an independent asynchronous reset input that clears all outputs regardless of the clock state.

How is data loaded into the counter?

Data is loaded synchronously via the parallel load inputs on the rising edge of the clock signal.
