CD4520BF3A

Counter Dividers Overview

The CD4520BF3A is a CMOS dual up-counter IC from the CD4520B series, manufactured by Texas Instruments. It features two independent synchronous binary counters within a single 16-lead hermetic dual-in-line ceramic package (CDIP). The device operates with a supply voltage range of 3 V to 18 V and supports an operating temperature range from -55°C to +125°C. Key functional attributes include gated clock inputs for precise timing control and Schmitt trigger action on the clock input to ensure clean signal transitions.

Counter Dividers Feature Summary

• Dual independent synchronous binary counter architecture
• Gated clock input functionality for controlled counting sequences
• Schmitt trigger action on clock input for noise immunity
• Hermetic ceramic packaging suitable for harsh environments

Counter Dividers Applications

• Military and defense electronic systems requiring radiation-hardened or high-reliability components
• Avionics and aerospace instrumentation utilizing wide temperature tolerance circuits
• Industrial control systems demanding robust digital counting logic under extreme conditions

Counter Dividers Procurement Notes

Verify the NRND status of this component before finalizing design specifications. Confirm that the specific F3A suffix corresponds to the required hermetic ceramic package variant. Ensure procurement channels can support military-grade qualification standards if applicable to the end application requirements.

Counter Dividers Selection Notes

Select this part when a hermetically sealed package is mandatory for environmental protection. Compare against plastic variants like CD4520BE if cost reduction is prioritized over hermeticity. Evaluate alternative catalog versions such as CD4520B-MIL for equivalent performance in standard military supply chains.

Counter Dividers Part Context

This component belongs to the CD4520B family of CMOS dual up-counters. It shares logical functionality with the CD4518B but differs in package options and specific manufacturing qualifications. The F3A suffix specifically denotes the hermetic ceramic construction distinct from standard plastic or small-outline packages offered in the same product line.
