What are the key features of CD4528BMN?

  • Dual independent monostable multivibrator channels with complementary Q/Q-bar outputs for flexible pulse generation
  • Wide supply voltage range of 3 V to 18 V compatible with both TTL and CMOS logic families
  • Retriggerable and resettable operation allowing dynamic pulse-width adjustment via external RC network
  • Robust 16-pin DIP package with noise immunity exceeding 45% of VDD for reliable operation in noisy environments

What is CD4528BMN used for?

The CD4528BMN is widely used for pulse-width generation and time delay applications in industrial control, alarm systems, and timing circuits. Its dual-channel architecture enables sequential triggering and debouncing of mechanical switch inputs in embedded systems. The wide supply range and complementary outputs also make it suitable for legacy 4000-series CMOS designs operating from 5 V to 15 V rails.

Frequently Asked Questions

How is the pulse width determined in CD4528BMN monostable circuits?

The output pulse width of each CD4528BMN channel is set by an external RC network connected to the CX and RX pins, with the relationship T ≈ 0.5 × R × C. For example, a 100 kΩ resistor and 0.1 µF capacitor yield approximately 5 ms pulse width, allowing designers to cover nanosecond to second ranges by choosing appropriate components.

What supply voltage range does CD4528BMN support, and how does it interact with TTL logic?

CD4528BMN operates from 3 V to 18 V supply voltage, spanning the full 4000-series CMOS range. When powered at 5 V, its output levels are TTL-compatible; at 15 V the high noise immunity of 45% VDD (6.75 V) makes it suitable for industrial environments with significant electrical interference.

When would a designer choose CD4528BMN over a microcontroller timer peripheral for pulse generation?

CD4528BMN is preferred when hardware-guaranteed one-shot timing is needed without firmware intervention, such as in watchdog circuits or power-sequencing delays up to several seconds. The 16-pin DIP form factor also suits breadboard prototyping and through-hole industrial boards where SMD assembly is unavailable, providing 2 independent timing channels in a single IC.

Can both channels of the CD4528BMN be cascaded for sequential delay generation?

Yes, the Q output of channel 1 can directly trigger the A input of channel 2, creating a sequential delay chain. With each channel capable of pulse widths from under 100 ns to over 1 s depending on the RC values, cascading produces total delays of up to 2 s or more while using only 1 IC and 4 passive components.
