DESCRIPTION

· The SN54221 and SN74221 are dual multivibrators with performance characteristics virtually identical to the SN54121 and SN74121 one shots.

· Each multivibrator features a negative-transition-triggered input and a positive-transition-triggered input, either of which can be used as an inhibit input.

· The pinout is identical to the SN54123, SN74123, SN54LS123, and SN74LS123.

· Overriding clear terminates the output pulse.

FEATURES

· Dual versions of highly stable one shots.

· Electrical and switching characteristics are virtually identical to the SN54121 and SN74121 one shots.

· Maximum output pulse lengths vary by model: SN54221 (21), SN74221 (28), SN54LS221 (49), SN74LS221 (70).

APPLICATIONS

· Suitable for use in critical applications where stable and reliable multivibrator performance is required.

· Ideal for applications requiring precise timing and pulse generation.

· Can be used in various electronic systems where dual multivibrators are needed.
