Description
:
The CD14538B dual precision monostable multivibrator provides stable retriggerable/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 output 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
. Precision control of output pulse widths is achieved through linear CMOS techniques.
Leading-edge-triggering (+TR) and trailing-edge-triggering (-TR) inputs are provided for triggering from either edge of an input pulse. An unused +TR input should be tied to V
SS
. An unused -TR input should be tied to V
DD
. A RESET (on low level) is provided for immediate termination of the output pulse or to prevent output pulses when power is turned on. An unused RESET input should be tied to V
DD
. However, if an entire section of the CD14538B is not used, its inputs must be tied to either V
DD
or V
SS
. 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-retriggerable 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 4 K
. The minimum and maximum values of external capacitance, C
X
are 0 pF and 100µF, respectively.
The CD14538B is interchangeable with type MC14538 and is similar to and pin-compatible with the CD4098B* and CD4538B. It can replace the CD4538B which type is not recommended for new designs.
