Description
The Harris CD74HC123, CD74HCT123, CD74HC423 and
CD74HCT423 are dual monostable multivibrators with
resets. They are all retriggerable and differ only in that the
123 types can be triggered by a negative to positive reset
pulse; whereas the 423 types do not have this feature. An
external resistor (R
X
) and an external capacitor (C
X
) control
the timing and the accuracy for the circuit. Adjustment of Rx
and C
X
provides a wide range of output pulse widths from
the Q and Q terminals. Pulse triggering on the A and B
inputs occur at a particular voltage level and is not related to
the rise and fall times of the trigger pulses.
Once triggered, the output pulse width may be extended by
retriggering inputs A and B. The output pulse can be
terminated by a LOW level on the Reset (R) pin. Trailing
edge triggering (A) and leading edge triggering (B) inputs
are provided for triggering from either edge of the input
pulse. If either Mono is not used each input on the unused
device (A, B, and R) must be terminated high or low.
The minimum value of external resistance, Rx is typically 5k
.
The minimum value external capacitance, C
X
, is 0pF. The
calculation for the pulse width is t

= 0.45 R
