CD14538BM

Multivibrators Overview

The CD14538BM is a CMOS dual precision monostable multivibrator from the Texas Instruments 4000B series. It integrates two independent circuits within a 16-SOIC package. The device operates on a supply voltage ranging from 3 V to 18 V and supports output currents of 6.8 mA for both high and low states. It features Schmitt trigger inputs and exhibits a propagation delay of 100 ns. The component functions reliably across an extended temperature range of -55°C to 125°C.

Multivibrators Feature Summary

• Dual precision monostable multivibrator configuration with two independent circuits
• Schmitt trigger inputs for noise immunity
• CMOS technology compatible with standard logic families

Multivibrators Applications

• Timing pulse generation
• Debouncing switches
• Frequency division

Multivibrators Procurement Notes

Verify the specific suffix against official datasheets, as variations may indicate different packaging or environmental ratings. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Ensure the source document matches the exact part number to avoid discrepancies in pinout or electrical characteristics.

Multivibrators Selection Notes

Select this component when dual independent timing channels are required in a compact surface-mount format. The wide operating voltage range and industrial temperature rating make it suitable for diverse environments. Verify that the 16-SOIC footprint aligns with the PCB layout constraints.

Multivibrators Part Context

This part belongs to the CD14538B family of CMOS dual precision monostable multivibrators. It is manufactured by Texas Instruments and is part of the broader 4000B series of logic devices. The 'BM' designation typically refers to the SOIC package variant.

Multivibrators Replacement Considerations

Direct substitutes include CD14538BM96 and CD14538BMT. Cross-manufacturer equivalents such as MC14538BDG from onsemi or HEF4538BT from Nexperia may be considered if pin compatibility is verified.
