CD4518BF3A

Counter Dividers Overview

The CD4518BF3A is a CMOS dual up-counter from the CD4000B series, manufactured by Texas Instruments. It contains two independent 4-bit binary counters with asynchronous reset inputs. The device operates within a supply voltage range of 3 V to 18 V and supports a maximum clock frequency of 8 MHz. It is housed in a 16-lead hermetic dual-in-line ceramic package (CDIP) with an F3A suffix. The component is rated for operation across a temperature range of -55°C to +125°C.

Counter Dividers Feature Summary

• Dual independent 4-bit BCD up-counters
• Asynchronous reset functionality
• Hermetic ceramic packaging

Counter Dividers Applications

• Military and defense applications requiring radiation-hardened or high-reliability components
• Spacecraft instrumentation and avionics systems
• Harsh environment industrial control logic

Counter Dividers Procurement Notes

Verify that the specific order includes the F3A suffix to ensure receipt of the hermetic ceramic package variant. Confirm RoHS compliance status as this military-grade package type may differ from standard commercial plastic packages. Check current production status and lead times directly with the manufacturer due to specialized packaging requirements.

Counter Dividers Selection Notes

Select this part when hermetic sealing is required for environmental protection or reliability standards. Compare against the CD4518BE for standard plastic DIP options if hermeticity is not needed. Ensure the design accommodates the larger physical footprint and higher cost associated with ceramic packaging compared to standard SOIC or TSSOP alternatives.

Counter Dividers Part Context

This component belongs to the CD4518B family of CMOS logic devices. It is functionally identical to the CD4520B but utilizes positive counting logic rather than negative counting. The F3A suffix specifically denotes the 16-lead hermetic dual-in-line ceramic package, distinguishing it from plastic variants like BE or BM.
