MC14528B Dual Monostable Multivibrator The MC14528B is a dual, retriggerable, resettable monostable multivibrator. It may be triggered from either edge of an input pulse, and produces an output pulse over a wide range of widths, the duration of which is determined by the external timing components, CX and RX. • • • • • • http://onsemi.com MARKING DIAGRAMS 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–power Schottky TTL Load Over the Rated Temperature Range Pin–for–Pin Replacement with the MC14538B 16 PDIP–16 P SUFFIX CASE 648 MC14528BCP AWLYYWW 1 16 SOIC–16 D SUFFIX CASE 751B 1 MAXIMUM RATINGS (Voltages Referenced to VSS) (Note 2.)

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high–impedance circuit. For proper operation, Vin and Vout should be constrained to the range VSS (Vin or Vout) VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open. v Semiconductor Components Industries, LLC, 2000 March, 2000 – Rev. 3 SOEIAJ–16 F SUFFIX CASE 966 MC14528B AWLYWW 1 2.
