MC14538B
Dual Precision
Retriggerable/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 T = RX @ CX (secs)
RX = W
CX = Farads
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 NegativeâGoing Edge (BâInput)
⢠Capable of Driving Two LowâPower TTL Loads or One LowâPower
Schottky TTL Load Over the Rated Temperature Range
⢠Pinâforâpin Compatible with MC14528B and CD4528B (CD4098)
⢠Use the MC54/74HC4538A for Pulse Widths Less Than 10 ms with
Supplies Up to 6 V
⢠NLV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AECâQ100
Qualified and PPAP Capable
⢠These Devices are PbâFree and are RoHS Compliant

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.

This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
highâimpedance circuit. For proper operation, Vin and Vout should be constrained
to the range VSS v (Vin or Vout) v VDD.
Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either VSS or VDD). Unused outputs must be left open.
