Features

Description

• Overriding RESET Terminates Output Pulse

• Triggering from the Leading or Trailing Edge

• Q and Q Buffered Outputs

The ’HC221 and CD74HCT221 are dual monostable

multivibrators with reset. An external resistor (R ) and an

external capacitor (C ) control the timing and the accuracy

for the circuit. Adjustment of R and C provides a wide

range of output pulse widths from the Q and Q terminals.

Pulse triggering on the B input occurs at a particular voltage

level and is not related to the rise and fall time of the trigger

pulse.

• Separate Resets

• Wide Range of Output-Pulse Widths

• Schmitt Trigger on B Inputs

• Fanout (Over Temperature Range)

Once triggered, the outputs are independent of further trigger

inputs on A and B. The output pulse can be terminated by a

and leading-edge-triggering (B) inputs are provided for

triggering from either edge of the input pulse. On power up,

the IC is reset. If either Mono is not used each input (on the

unused device) must be terminated either high or low.

• Signiﬁcant Power Reduction Compared to LSTTL

Logic ICs

The minimum value of external resistance, R , is typically 500Ω.

• HC Types

The minimum value of external capacitance, C , is 0pF. The

calculation for the pulse width is t = 0.7 R C at V = 4.5V.
