HEF4528BT,652

Multivibrators Overview

The HEF4528BT,652 is a dual retriggerable-resetable monostable multivibrator from the Nexperia HEF4000B series. It operates within a supply voltage range of 3 V to 15 V and supports an ambient temperature range of -40 °C to +85 °C. The device features fully static operation with CMOS low power dissipation and high noise immunity. It includes two independent channels, each providing active LOW (nA) and active HIGH (nB) inputs, an active LOW clear direct input (nCD), and complementary outputs (nQ and nQ). Pulse duration is determined by external timing components connected to pins nREXT/CEXT and nCEXT.

Multivibrators Feature Summary

• Dual retriggerable and resetable monostable multivibrator architecture
• Wide supply voltage range supporting 3.0 V to 15.0 V operation
• High noise immunity with standardized symmetrical output characteristics
• ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Multivibrators Applications

• Non-retriggerable monostable multivibrator circuits
• Timing pulse generation using external RC networks
• Signal conditioning and edge triggering applications

Multivibrators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape/reel specifications. Ensure the component meets the required JEDEC standards for your design environment. Confirm that the SO16 plastic small outline package aligns with your PCB footprint requirements before finalizing procurement.

Multivibrators Selection Notes

Select this component when a dual-channel monostable solution is required with wide voltage tolerance. It is suitable for designs needing both positive and negative pulse outputs simultaneously. Consider the external timing resistor and capacitor constraints defined in the datasheet to ensure accurate pulse width generation across the specified temperature range.

Multivibrators Part Context

This part belongs to the HEF4000B logic family, which utilizes CMOS technology for low power consumption. The HEF4528B variant specifically provides two identical monostable multivibrator circuits in a single package. It is designed for general-purpose digital applications requiring reliable pulse generation and signal delay functions.

Multivibrators Replacement Considerations

Check for pin-compatible alternatives within the same logic family or other manufacturers offering dual monostable multivibrators in SO16 packages. Verify that any substitute maintains the same supply voltage range and ESD protection levels.
