HEF4528B
Dual monostable multivibrator
Rev. 10 — 14 March 2017 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 Figure 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.

PD can be calculated from the formulas shown. VSS = 0 V; tr = tf ≤ 20 ns; Tamb = 25 °C.
Symbol Parameter VDD Typical formula for PD (μW) where:

Short data sheet — A short data sheet is an extract from a full data sheet
with the same product type number(s) and title. A short data sheet is
intended for quick reference only and should not be relied upon to contain
detailed and full information. For detailed and full information see the
relevant full data sheet, which is available on request via the local Nexperia
sales office. In case of any inconsistency or conflict with the short data sheet,
the full data sheet shall prevail.
Product specification — The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
Nexperia and its customer, unless Nexperia and customer have explicitly
agreed otherwise in writing. In no event however, shall an agreement be
valid in which the Nexperia product is deemed to offer functions and qualities
beyond those described in the Product data sheet.

specifications and product descriptions, at any time and without notice. This
document supersedes and replaces all information supplied prior to the
publication hereof.
Suitability for use — Nexperia products are not designed, authorized or
warranted to be suitable for use in life support, life-critical or safety-critical
systems or equipment, nor in applications where failure or malfunction
of an Nexperia product can reasonably be expected to result in personal
injury, death or severe property or environmental damage. Nexperia and its
suppliers accept no liability for inclusion and/or use of Nexperia products in
such equipment or applications and therefore such inclusion and/or use is at
the customer’s own risk.
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. Nexperia makes no representation
or warranty that such applications will be suitable for the specified use
without further testing or modification. Customers are responsible for the
design and operation of their applications and products using Nexperia
products, and Nexperia accepts no liability for any assistance with
applications or customer product design. It is customer’s sole responsibility
to determine whether the Nexperia product is suitable and fit for the
customer’s applications and products planned, as well as for the planned
application and use of customer’s third party customer(s). Customers should
provide appropriate design and operating safeguards to minimize the risks
associated with their applications and products. Nexperia does not accept
any liability related to any default, damage, costs or problem which is based
on any weakness or default in the customer’s applications or products, or
the application or use by customer’s third party customer(s). Customer is
responsible for doing all necessary testing for the customer’s applications
and products using Nexperia products in order to avoid a default of the
applications and the products or of the application or use by customer’s third
party customer(s). Nexperia does not accept any liability in this respect.
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
