MC14538BDWR2G

Multivibrators Overview

The MC14538BDWR2G is a dual precision monostable multivibrator manufactured by onsemi. It operates within a supply voltage range of 3.0 Vdc to 18 Vdc and supports an operating temperature range from -55°C to +125°C. The device features latched trigger inputs and separate latched reset inputs, allowing for retriggerable and resettable operation. Output pulse widths are determined by external timing components RX and CX, covering a range from 10 microseconds to 10 seconds. It is housed in a SOIC-16WB package.

Multivibrators Feature Summary

• Dual precision monostable multivibrator with retriggerable and resettable functionality
• Triggerable from either positive-going edge (A input) or negative-going edge (B input)
• Capable of driving two low-power TTL loads or one low-power Schottky TTL load
• Pin-for-pin compatible with MC14528B and CD4528B (CD4098)

Multivibrators Applications

• Timing delay circuits
• Pulse width modulation generation
• Frequency division
• Touch-sensitive switches

Multivibrators Procurement Notes

Verify the specific ordering suffix 'DW' corresponds to the SOIC-16 Wide Body package configuration. Confirm that the 'G' suffix indicates lead-free and RoHS compliance status as per manufacturer specifications. Ensure compatibility with AEC-Q100 requirements if automotive qualification is necessary, noting that NLV prefixes typically denote these specific control changes.

Multivibrators Selection Notes

Select this component when dual independent monostable circuits are required within a single package. Consider the wide supply voltage range and temperature stability for industrial applications. Verify that external timing components RX and CX can provide the desired pulse width accuracy. Check pin compatibility with existing designs referencing MC14528B or CD4528B for direct replacement scenarios.

Multivibrators Part Context
