High Speed CMOS Logic Dual Retriggerable

Monostable Multivibrators with Resets

Features

Description

• Overriding Reset Terminates Output Pulse

• Triggering From the Leading or Trailing Edge

• Q and Q Buffered Outputs

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

• Separate Resets

external resistor (R ) and an external capacitor (C ) control

the timing and the accuracy for the circuit. Adjustment of Rx

• Wide Range of Output-Pulse Widths

• Schmitt Trigger on Both A and B Inputs

and C 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.

• Fanout (Over Temperature Range)

- Standard Outputs. . . . . . . . . . . . . . . 10 LSTTL Loads

- Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads

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.

• Wide Operating Temperature Range . . . -55 C to 125 C

• Balanced Propagation Delay and Transition Times

• Signiﬁcant Power Reduction Compared to LSTTL
