Product Description
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,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 = (Cx) (Rx) where:
Rx is in k
Cx is in F
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.
