MC14538BFR1

Dual Precision Retiggerable/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 = Cx Rx where:

   Rx is in kΩ

   Cx is in μF

  

• Unlimited Rise and Fall Time Allowed on the A Trigger Input

• Pulse Width Range = 10 µs 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 µs with Supplies Up to 6 V.
