SN74221J

The SN74221J is one of the SN74221 series.The SN74221J devices are dual multivibrators with performance characteristics virtually identical to those of the '121 devices.Each multivibrator features a negative-transitiontriggered input and a positive-transition triggered input, either of which can be used as an inhibit input.

Features of the SN74221J are:(1)Dual Versions of Highly Stable SN74121 One Shots; (2) SN74221 Demonstrate Electrical and Switching Characteristics That Are Virtually Identical to the SN54121 and SN74121 One Shots; (3)Pinout Is Identical to the SN54123,SN74123, SN54LS123, and SN74LS123; (4)Overriding Clear Terminates Output Pulse.

The absolute maximum ratings of the SN74221J can be summarized as:(1)supply voltage,VCC:7V; (2)input voltage:5.5V; (3)Package thermal impedance, JA (see Note 2): D package 73 °C/W;DB package 82°C/W;N package 67 °C/W;NS package 64 °C/W; (4)storage temperature range:-65 to 150.

The electrical characteristics(Ta=25) of the SN74221J can be summarized as:(1)VIK:-1.5V; (2)VOH:2.7V MIN 3.4V TYP; (3)II:0.1mA; (4)IIH:20A.If you want to know more information such as the electrical characteristics ,please download the datasheet in www.seekdatasheet.com .
