CD14538BMS
CMOS Dual Precision
Monostable Multivibrator
Description
CD14538BMS dual precision monostable multivibrator provides stable retrigger-
able/resettable one-shot operation for any fixed-voltage timing application.
An external resistor (R
X
) and an external capacitor (C
X
) control the timing and
accuracy for the circuit. Adjustment of R
X
and C
X
provides a wide range of out-
put pulse widths from the Q and Q terminals. The time delay from trigger input to
output transition (trigger propagation delay) and the time delay from reset input
to output transition (reset propagation delay) are independent of R
X
and C
X
. Pre-
cision control of output pulse widths is achieved through linear CMOS tech-
niques.
Leading-edge-triggering (+TR) and trailing-edge-triggering (-TR) inputs are pro-
vided for triggering from either edge of an input pulse. An unused +TR input
should be tied to VSS. An unused -TR input should be tied to VDD. A RESET
(on low level) is provided for immediate termination of the output pulse or to pre-
vent output pulses when power is turned on. An unused RESET input should be
tied to VDD. However, if an entire section of the CD14538BMS is not used, its
inputs must be tied to either VDD or VSS. See Table 1.
In normal operation the circuit retriggers (extends the output pulse one period)
on the application of each new trigger pulse. For operation in the non-retrigger-
able mode, Q is connected to -TR when leading-edge triggering (+TR) is used
or Q is connected to +TR when trailing-edge triggering (-TR) is used. The time
period (T) for this multivibrator can be calculated by: T = R
X
C
X
.
The minimum value of external resistance, R
X
is 4K
. The minimum and maxi-
mum values of external capacitance, C
X
, are 0pF and 100
µ
F, respectively.
The CD14538BMS is interchangeable with type MC14538 and is similar to and
pin-compatible with the CD4098B* and CD4538B**.
