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, CX 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

#Data labelled “Typ” is not to be used for design purposes but is intended as an indication of the IC’s potential performance.

** The formulas given are for the typical characteristics only at 25_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 VSS ≤ (Vin or V

out

) ≤ 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.
