NTE4528B & NTE4528BT
Integrated Circuit
CMOS, Dual Retriggerable/Resettable
Monostable Multivibrator
Description:
The NTE4528B (16−Lead DIP) and NTE4528BT (SOIC−16) are dual, retriggerable, resettable
monostable multivibrators that 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.
Features:
D Diode Protection on All Inputs
D Triggerable from Leading or Trailing Edge Pulse
D Supply Voltage Range = 3Vcd to 18Vdc
D Capable of Driving Two Low−Power TTL Loads or One Low−Power Schottky TTL Load Over
the Rated Temperature Range
D These devices should only be used in circuits where he pulse width is < 10μs. For circuits
requiring a pulse width > 10μs, please see NTE4538B, which is pin−for−pin compatible.

Note 1. Stresses exceeding Absolute Maximum Ratings may damage the device. Maximum Rat-
ings are stress ratings only. Functional operation above the Recommended Operating
Conditions is not implied. Extended exposure to stresses above the Recommended Op-
erating Conditions may affect device reliability.
These devices contain 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 prop-
er operation, Vin and Vout should be constrained to the range VSS ≤ (Vin or Vout) ≤ VDD
.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS
or VDD).
