MC14538B

MC14538B Dual Precision Retriggerable/Resettable Monostable Multivibrator The MC14538B is a dual, retriggerable, resettable monostable multivibrator. It may be triggered from either edge of an input pulse, and produces an accurate output pulse over a wide range of widths, the duration and accuracy of which are determined by the external timing components, CX and RX. Output Pulse Width T = RX @ CX (secs) RX = W CX = Farads Features Unlimited Rise and Fall Time Allowed on the A Trigger Input Pulse Width Range = 10 ms to 10 s Latched Trigger Inputs Separate Latched Reset Inputs 3.0 Vdc to 18 Vdc Operational Limits Triggerable from Positive (A Input) or Negative−Going Edge (B−Input) Capable of Driving Two Low−Power TTL Loads or One Low−Power Schottky TTL Load Over the Rated Temperature Range Pin−for−pin Compatible with MC14528B and CD4528B (CD4098) Use the MC54/74HC4538A for Pulse Widths Less Than 10 ms with Supplies Up to 6 V NLV Prefi...
