Dual monostable multivibrator
HEF4528B
MSI
DESCRIPTION
The HEF4528B is a dual retriggerable-resettable
monostable multivibrator. Each multivibrator has an active
LOW input (I
0
), and active HIGH input (I
1
), an active LOW
clear direct input (C
D
), an output (O) and its complement
(O), and two pins for connecting the external timing
components (C
TC(1)
, RC
TC
).
An external timing capacitor (C
t
) must be connected
between C
TC
and RC
TC
and an external resistor (R
t
) must
be connected between RC
TC
and V
DD
. The duration of the
(1) Always connected to ground.
output pulse is determined by the external timing
components C
t
and R
t
.
A HIGH to LOW transition on I
0
when I
1
is LOW or a LOW
to HIGH transition on I
1
when I
0
is HIGH produces a
positive pulse (LOW-HIGH-LOW) and O and a negative
pulse (HIGH-LOW-HIGH) on O if the C
D
is HIGH. A LOW
on C
D
forces O LOW, O HIGH and inhibits any further
pulses until C
D
is HIGH.
