DESCRIPTION/ORDERING INFORMATION (CONTINUED)
Pin assignments are identical to those of the SN74AHC123A and SN74AHCT123A devices, so the
SN74LV221A-Q1 can be substituted for those devices not using the retrigger feature.
For additional application information on multivibrators, see the application report Designing With The
SN74AHC123A and SN74AHCT123A, literature number SCLA014.

This condition is true only if the output of the latch formed by the NAND gate has been conditioned to the logic 1 state prior to CLR
going high. This latch is conditioned by taking either A high or B low while CLR is inactive (high).
