CD4098BF3A

Multivibrators Overview

The CD4098BF3A is a dual monostable multivibrator manufactured by Texas Instruments, belonging to the 4000B series of CMOS logic devices. It features two independent circuits housed in a 16-lead hermetic ceramic dual-in-line package (CDIP). The device operates within a supply voltage range of 3V to 18V and supports an operating temperature range from -55°C to 125°C. Key electrical parameters include a maximum propagation delay of 100ns and output currents of 6.8mA for both high and low states. The component is RoHS non-compliant and utilizes SNPB lead finish.

Multivibrators Feature Summary

• Dual monostable multivibrator architecture providing two independent timing circuits
• Hermetic ceramic packaging suitable for harsh environments
• Wide operating voltage range supporting diverse power supply conditions

Multivibrators Applications

• Military and defense applications requiring radiation-hardened or hermetic components
• Precision timing and pulse generation circuits
• Debounce switches and level shifting interfaces

Multivibrators Procurement Notes

Verify that the specific order requires the F3A suffix, which denotes the hermetic ceramic package. Confirm that the procurement specification explicitly accepts non-RoHS compliant materials, as this variant does not meet standard environmental directives. Ensure the design environment accommodates the specified wide temperature range and hermetic sealing requirements before finalizing the purchase.

Multivibrators Selection Notes

Select the CD4098BF3A when hermetic sealing is mandatory for reliability in extreme environments. This part is distinct from plastic or SOIC variants due to its ceramic construction. Verify compatibility with existing PCB layouts designed for dual-in-line ceramic packages. Consider the non-RoHS status during the selection process to ensure compliance with project-specific material regulations.

Multivibrators Part Context

This component is part of the broader CD4098B family, which includes various package options such as plastic DIP, SOIC, and TSSOP. The BF3A suffix specifically identifies the hermetic ceramic dual-in-line version. While other variants share similar electrical characteristics, the physical construction and environmental ratings differ significantly based on the package type selected.

Multivibrators Replacement Considerations

Direct replacements include other CD4098B variants with different package suffixes if hermeticity is not required. For military specifications, verify availability of QML certified versions. Cross-reference with MC14528 equivalents if pinout compatibility is the primary constraint.
