Description

The SN74LS221D is a dual Monostable Multivibrator with schmitt-trigger inputs. Its 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. Pulse triggering occurs at a particular voltage level and is not directly related to the transition time of the input pulse. Schmitt-trigger input circuitry for B input allows jitter-free triggering from inputs with transition rates as slow as 1V/s, providing the circuit with excellent noise immunity, typically of 1.2V. A high immunity to VCC noise, typically of 1.5V, is also provided by internal latching circuitry. Once fired, the outputs are independent of further transitions of the A and B inputs and are a function of the timing components or the output pulses can be terminated by the overriding clear. Input pulses can be of any duration relative to the output pulse.
Overriding clear terminates output pulse
