HEF4528B Datasheet – Dual Monostable Multivibrator

Part Number : HEF4528B

Function : Dual Monostable Multivibrator

Package : SOIC 16 Pin Type

Manufacturers : NXP Semiconductors.

Pinouts :

HEF4528B datasheet

 

Description :

The HEF4528B is a dual retriggerable-resetable monostable multivibrator. Each multivibrator has an active LOW input (nA), and active HIGH input (nB), an active LOW clear direct input (nCD), an output (nQ) and its complement (nQ), and two external timing component connecting pins (nCEXT, always connected to ground, and nREXT/CEXT).

It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS
(usually ground). Unused inputs must be connected to VDD, VSS, or another input.

 

Features :

1. Fully static operation

2. 5 V, 10 V, and 15 V parametric ratings

3. Standardized symmetrical output characteristics

4. Specified from -40 °C to +85 °C

5. Complies with JEDEC standard JESD 13-B

CD4047BCN Datasheet – Monostable / Astable Multivibrator

Part Number : CD4047BCN

Function : Low Power Monostable / Astable Multivibrator

Package : DIP 14 Pin

Manufacturers : Fairchild Semiconductor

Pinouts :

CD4047BCN datasheet

 

Description :

The CD4047B, CD4047BCN is capable of operating in either the monostable or astable mode. It requires an external capacitor (between pins 1 and 3) and an external resistor (between pins 2 and 3) to determine the output pulse width in the monostable mode, and the output frequency in the astable mode.

Astable operation is enabled by a high level on the astable input or low level on the astableinput. The output frequency (at 50% duty cycle) at Q and Qoutputs is determined by the timing components. A frequency twice that of Q is available at the Oscillator Output; a 50% duty cycle is not guaranteed.

 

Features :

1. Wide supply voltage range: 3.0V to 15V

2. High noise immunity: 0.45 VDD (typ.)

3. Low power TTL compatibility: Fan out of 2 driving 74L or 1 driving 74LS

Applications :

1. Frequency discriminators

2. Timing circuits

3. Time-delay applications

4. Envelope detection

5. Frequency multiplication

6. Frequency division
