SN54221W

The SN54221W is one of the SN54221 series. The SN54221W device is dual multivibrators with performance characteristics virtually identical to those of the '121 devices.Each multivibrator features a vegative-transition-triggered input,either of which can be used as an inbibit input.

Features of the SN54221W are:(1)Dual Versions of Highly Stable SN54121 and SN74121 One Shots; (2)SN54221 and 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 SN54221W can be summarized as:(1)Supply voltage range, VCC:7 V; (2)Input voltage range, VI:5.5 V; (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, Tstg:-65°C to 150°C.

The electrical characteristics(Ta=25) of the SN54221W can be summarized as:(1)VIK:-1.5V MAX; (2)VOL:0.2V TYP 0.4V MAX; (3)II:1mA;(4)IOS:-20mA MIN -55mA MAX; (5)ICC:26mA TYP 50mA MAX;(6)VOH:2.4V MIN 3.4V MAX.If you want to know more information such as the electrical characteristics of SN54221W ,please download the datasheet in www.seekdatasheet.com .
