CD4516BF3A

Counter Dividers Overview

The CD4516BF3A is a CMOS presettable binary up/down counter manufactured by Texas Instruments. It operates within a supply voltage range of 3V to 18V and supports clock frequencies up to 11 MHz. The device features four data inputs, four outputs, and a bidirectional counting mode controlled by an Up/Down input. It includes asynchronous load and reset functions for flexible system integration. The component is housed in a 16-lead hermetic dual-in-line ceramic package (CDIP) with a J-style lead form.

Counter Dividers Feature Summary

• CMOS technology provides low power consumption and high noise immunity
• Bidirectional counting capability allows for both incrementing and decrementing operations
• Asynchronous load function enables immediate parallel data entry
• Hermetic ceramic packaging ensures reliability in harsh environments

Counter Dividers Applications

• Military and defense applications requiring radiation or moisture resistance
• High-reliability industrial control systems
• Avionics and aerospace instrumentation
• Precision timing and frequency division circuits

Counter Dividers Procurement Notes

Verify the F3A suffix confirms the 16-lead hermetic ceramic dual-in-line package. Confirm RoHS exemption status as indicated in the Package Option Addendum. Ensure the supplier provides traceability documentation suitable for military or high-reliability procurement requirements. Check for active production status and availability of qualified versions.

Counter Dividers Selection Notes

Select this part when hermetic sealing is required for environmental protection. Compare against plastic packages like BE or NSR if cost or standard commercial use is sufficient. Verify that the 16-pin CDIP footprint matches the PCB design. Consider thermal management and mounting constraints associated with ceramic packages.

Counter Dividers Part Context

The CD4516B series belongs to the 4000/14000/40000 logic families. The BF3A variant specifically denotes the hermetic ceramic construction. Other variants include plastic DIP (BE), small-outline (NSR), and thin shrink small-outline (PW/PWR). The family offers general-purpose binary counting with preset capabilities.

Counter Dividers Replacement Considerations

Qualified substitutes include other CD4516B variants with different packages such as CD4516BE or CD4516BNSR. Military-qualified versions like CD4516B-MIL may be available. Verify pinout compatibility and electrical specifications before substitution.
