MC14528B
Dual Monostable
Multivibrator
The MC14528B is a dual, retriggerable, resettable monostable
multivibrator. It may be triggered from either edge of an input pulse,
and produces an output pulse over a wide range of widths, the duration
of which is determined by the external timing components, C
X
and
RX.
• Separate Reset Available
• Diode Protection on All Inputs
• Triggerable from Leading or Trailing Edge Pulse
• Supply Voltage Range = 3.0 Vdc to 18 Vdc
• Capable of Driving Two Low–power TTL Loads or One Low–power
Schottky TTL Load Over the Rated Temperature Range
• Pin–for–Pin Replacement with the MC14538B

2. Maximum Ratings are those values beyond which damage to the device
may occur.
3. Temperature Derating:
Plastic “P and D/DW” Packages: – 7.0 mW/_C From 65_C T o 125_C
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
high–impedance circuit. For proper operation, Vin and V
out
should be constrained
to the range V
SS
v (Vin or V
out
) v VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
either V
SS
or VDD). Unused outputs must be left open.
