description/ordering information
The
’221
and
’LS221
devices
are
dual
multivibrators with performance characteristics
virtually identical to those of the ’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.
