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.

? 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.
