MC14528B Dual Monostable Multivibrator

The MC14528B is a dual, retriggerable, resettable monostablemultivibrator. It may be triggered from either edge of an input pulse,and produces an output pulse over a wide range of widths, the durationof which is determined by the external timing components,C X and R X .• Separate Reset Available• Diode Protection on All Inputs• Triggerable from Leading or Trailing Edge Pulse• Supply Voltage Range = 3.0 Vdc to 18 Vdc• Capable of Driving Two Low–power TTL Loads or One Low–powerSchottky TTL Load Over the Rated Temperature Range• This part should only be used in new designs where the pulse widthis < 10 s.Note: For designs requiring a pulse width > 10 s, please see theMC14538, which is pin–for–pin compatible.MAXIMUM RATINGS (Voltages Referenced to V SS ) (Note 2.)Symbol Parameter Value UnitV DD DC Supply Voltage Range –0.5 to +18.0 VV in , V out Input or Output Voltage Range(DC or Transient)–0.5 to V DD + 0.5 VI in , I outP DInput or Output Current(DC or Transient) per PinPower Dissipation,per Package (Note 3.)±10 mA500 mWT A Ambient Temperature Range –55 to +125 °CT stg Storage Temperature Range –65 to +150 °CT LLead Temperature(8–Second Soldering)260 °C2. Maximum Ratings are those values beyond which damage to the devicemay occur.3. Temperature Derating:Plastic “P and D/DW” Packages: – 7.0 mW/C From 65C To 125CThis device contains protection circuitry to guard against damage due to highstatic voltages or electric fields. However, precautions must be taken to avoidapplications of any voltage higher than maximum rated voltages to thishigh–impedance circuit. For proper operation, V in and V out should be constrainedto the range V SS (V in or V out ) V DD .Unused inputs must always be tied to an appropriate logic voltage level (e.g.,either V SS or V DD ). Unused outputs must be left open.AWL, LYY, YWW, Whttp://onsemi.comPDIP–16P SUFFIXCASE 648SOIC–16D SUFFIXCASE 751BSOEIAJ–16F SUFFIXCASE 966= Assembly Location= Wafer Lot= Year= Work WeekORDERING INFORMATIONMARKINGDIAGRAMSDevice Package ShippingMC14528BCP PDIP–16 2000/BoxMC14528BD SOIC–16 48/RailMC14528BDR2 SOIC–16 2500/Tape & Reel1.
