SEMICONDUCTOR TECHNICAL DATA

Dual Monostable Multivibrator

The MC14528B is a dual, retriggerable, resettable monostable multivibra-

tor. 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

ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ Schottky TTL Load Over the Rated Temperature Range

• Pin–for–Pin Replacement with the MC14538B
