The โ€™221 and โ€™LS221 devices are dual
multivibrators with performance characteristics
virtually identical to those of the โ€™121 devices.
Each multivibrator features a negative-transition-
triggered input and a positive-transition-triggered
input, either of which can be used as an inhibit
input.
