MC14538B
Dual Precision
Retriggerable/Resettable
Monostable Multivibrator
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 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
ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ Supplies Up to 6 V.
