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.

Device MC14528BCP MC14528BD MC14528BDR2 MC14528BF MC14528BFEL Package PDIP-16 SOIC-16 SOIC-16 SOEIAJ-16 SOEIAJ-16 Shipping 2000/Box 48/Rail 2500/Tape & Reel See Note 1. See Note 1.
2. Maximum Ratings are those values beyond which damage to the device may occur. 3. Temperature Derating: Plastic "P and D/DW" Packages: - 7.0 mW/_C From 65_C To 125_C This device contains protection circuitry to guard against damage due to high static voltages or electric fields. 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.
