HEF4528B
Dual monostable multivibrator
Rev. 11 — 4 March 2022
Product data sheet
1. General description
The HEF4528B is a dual retriggerable-resetable monostable multivibrator. Each multivibrator has
an active LOW input (nA), and active HIGH input (nB), an active LOW clear direct input (nCD), an
output (nQ) and its complement (nQ), and two external timing component connecting pins (nCEXT,
always connected to ground, and nREXT/CEXT).
An external timing capacitor (CEXT) must be connected between nCEXT and nREXT/CEXT and
an external resistor (REXT) must be connected between nREXT/CEXT and VDD. The output
pulse duration is determined by the external timing components CEXT and REXT. A HIGH-to-LOW
transition on nA when nB is LOW or a LOW-to-HIGH transition on nB when nA is HIGH produces
a positive pulse (LOW-HIGH-LOW) on nQ and a negative pulse (HIGH-LOW-HIGH) on nQ if the
nCD is HIGH. A LOW on nCD forces nQ LOW, nQ HIGH and inhibits any further pulses until nCD
is HIGH.
It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually
ground). Unused inputs must be connected to VDD, VSS, or another input.

[1] The typical values of the propagation delay and transition times are calculated from the extrapolation formulas shown (CL in pF).
[2] tt is the same as tTHL and tTLH
.
[3] For other REXT, CEXT combinations and CEXT < 0.01 μF see Fig. 4.
[4] For other REXT, CEXT combinations and CEXT > 0.01 μF use formula tW = K × REXT × CEXT
.
where: tW = output pulse width (s);
REXT = external timing resistor (Ω);
CEXT = external timing capacitor (F);
K = 0.42 for VDD = 5 V;
K = 0.32 for VDD = 10 V;
K = 0.30 for VDD = 15 V.
[5] Tamb = -40 °C to +85 °C; ΔtW is referenced to tW at Tamb = 25 °C.

PD can be calculated from the formulas shown. VSS = 0 V; tr = tf ≤ 20 ns; Tamb = 25 °C.

Definitions
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those
given in the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.

internal review and subject to formal approval, which may result in
modifications or additions. Nexperia does not give any representations or
warranties as to the accuracy or completeness of information included herein
and shall have no liability for the consequences of use of such information.
Short data sheet — A short data sheet is an extract from a full data sheet
