CD4040BF3A

Counter Dividers Overview

The CD4040BF3A is a 12-stage binary ripple counter integrated circuit 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 utilizes asynchronous reset functionality and negative edge triggering for clock inputs. It is housed in a 16-lead hermetic dual-in-line ceramic package (CDIP) with the F3A suffix, designed for high-reliability applications.

Counter Dividers Feature Summary

• Provides 12-bit binary counting capability using asynchronous ripple architecture
• Features asynchronous reset control for immediate state clearing
• Utilizes negative edge-triggered clock inputs for stage progression
• Constructed in hermetically sealed ceramic packaging for environmental protection

Counter Dividers Applications

• Military and defense electronic systems requiring radiation-hardened or high-reliability components
• Avionics instrumentation and control circuits
• Spacecraft telemetry and data handling subsystems
• Harsh environment industrial monitoring equipment

Counter Dividers Procurement Notes

Verify that the specific orderable part number matches the required package type and lead finish. Confirm RoHS compliance status as indicated in the manufacturer's documentation, noting that the F3A suffix typically denotes non-RoHS hermetic ceramic construction. Ensure the supplier provides traceability documentation consistent with military or aerospace procurement standards if applicable.

Counter Dividers Selection Notes

Select this component when a hermetically sealed ceramic package is mandatory for environmental sealing or thermal stability. The F3A suffix specifically indicates the 16-lead CDIP format. Compare against plastic variants like the BE suffix if hermeticity is not required. Verify that the 3 V to 18 V supply range aligns with the system power architecture.

Counter Dividers Part Context

This component belongs to the CD4000B series of CMOS logic devices produced by Texas Instruments. The CD4040B variant specifically functions as a 12-stage binary counter. The BF3A designation identifies the specific hermetic ceramic package option within this product family, distinguishing it from standard plastic or surface-mount alternatives.
