SN7409

The SN7409 devices contain four independent 2-input AND gates.The open-collector outputs requie pull-up resistors to perform correctly.They may be connected to other open-collector outputs to implement active-low wired-OR or active-high wired-AND functions.Open-collector devices are often used to generate higher VOH levels.

Features of the SN7409 are:(1)package options include plastic"small outline"packages,ceramic chip carriers and flat packages,and plastic and ceramic DIPs; (2)dependable texas instruments quality and reliability.

The absolute maximum ratings of the SN7409 can be summarized as:(1)supply voltage,VCC:7V; (2)input voltage:5.5V; (3)operating free-air temperature range:0 to70; (4)storage temperature range:-65 to 150.

The electrical characteristics(Ta=25) of the SN7409 can be summarized as:(1)VIK:-1.5V MAX; (2)II:1mA; (3)IIH:40A; (6)ICCH:11mA TYP  21mA MAX;(4)ICCL:20mA TYP 33mA MAX.If you want to know more information such as the electrical characteristics of SN7409,please download the datasheet in www.seekdatasheet.com .
