MC14538B
The MC14538B is a dual, retriggerable, resettable monostable multivibra-
tor. 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

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)
