MC14538BDTR2G

Multivibrators Overview

The MC14538BDTR2G is a dual precision retriggerable and resettable 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 triggering from either the positive edge (A input) or negative-going edge (B input). Output pulse width is determined by external timing components RX and CX, with a typical range spanning from 10 nanoseconds to 10 seconds.

Multivibrators Feature Summary

• Dual precision monostable multivibrator architecture with independent timing control for each channel
• Supports both retriggerable and resettable operation modes for flexible pulse generation
• Capable of accepting triggers from positive or negative signal edges via dedicated A and B inputs
• Latched trigger and reset inputs ensure stable state transitions without requiring continuous input signals

Multivibrators Applications

• Pulse width modulation circuits requiring precise timing control
• Debouncing switches or contacts to generate clean digital pulses
• Timing delay generation in sequential logic systems
• Frequency division and pulse stretching applications

Multivibrators Procurement Notes

Verify that the ordering suffix BDTR2G corresponds to the TSSOP-16 package configuration as specified in the datasheet. Confirm RoHS compliance and lead-free status are required for the specific manufacturing site. Ensure the application environment stays within the rated -55°C to +125°C temperature limits to maintain parameter accuracy.

Multivibrators Selection Notes

Select this component when dual independent monostable channels are needed in a compact surface-mount footprint. It is suitable for designs requiring wide pulse width adjustability using external RC networks. Consider the pin-for-pin compatibility with MC14528B and CD4528B if migrating from legacy designs. Verify that the external timing components can handle the leakage currents associated with high resistance values.

Multivibrators Part Context

This part belongs to the MC14538B family of CMOS monostable multivibrators. It is functionally equivalent to the MC14528B and CD4528B/CD4098 devices, offering pin-for-pin compatibility. The BDTR2G suffix specifically denotes the TSSOP-16 package variant produced by onsemi, distinguishing it from SOIC-16 versions like the BDR2G.
