CD14538BF3A

Multivibrators Overview

The CD14538BF3A is a CMOS dual precision monostable multivibrator manufactured by Texas Instruments. It contains two independent circuits within a single package. The device operates on a supply voltage ranging from 3 V to 18 V and supports an operating temperature range of -55°C to +125°C. It utilizes a 16-lead hermetic dual-in-line ceramic package (CDIP) identified by the F3A suffix. The component features Schmitt trigger inputs for noise immunity.

Multivibrators Feature Summary

• Dual precision monostable multivibrator architecture
• Hermetic dual-in-line ceramic packaging
• Schmitt trigger input functionality

Multivibrators Applications

• Timing pulse generation
• Debouncing switches
• Pulse width modulation

Multivibrators Procurement Notes

Verify the specific ordering suffix F3A to confirm the 16-lead hermetic dual-in-line ceramic package configuration. Ensure compatibility with high-reliability requirements, as this variant is designated NRND. Confirm RoHS exemption status and lead finish specifications during procurement to match assembly processes.

Multivibrators Selection Notes

Select this component when hermetic sealing is required for harsh environments or military applications. The F3A suffix specifically denotes the ceramic package type. Compare against plastic variants like the BE or SOIC types if environmental sealing is not necessary. Verify pinout compatibility with existing designs referencing the CD4098B or CD4538B.

Multivibrators Part Context

This part belongs to the CD14538B series of CMOS logic devices. It serves as a replacement for older non-CMOS monostable multivibrators. The device is functionally similar to the CD4538B but offers improved performance characteristics suitable for precision timing applications requiring wide voltage operation.

Multivibrators Replacement Considerations

The datasheet states it can replace the CD4538B, which is not recommended for new designs. Pin-compatible alternatives include the MC14538 and CD4098B.
