SN54173J

The  SN54173J is one of the SN54173 series. TheSN54173J 4-bit registers include D-type flip-flops featuring totem-pole 3-state outputs capable of driving highly capacitive or relatively low-impedance loads. The high-impedance third state and increased high-logic-level drive provide these flip-flops with the capability of being connected directly to and driving the bus lines in a bus-organized system without need for interface or pull-up components.

Features of the SN54173J are:(1) 3-State Outputs Interface Directly With System Bus; (2) Gated Output-Control LInes for Enabling or Disabling the Outputs; (3) Fully Independent Clock Virtually Eliminates Restrictions for Operating in One of Two Modes:Parallel Load;Do Nothing (Hold); (4) For Application as Bus Buffer Registers; (5) Package Options Include Plastic Small-Outline (D) Packages, Ceramic Flat(W) Packages, Ceramic Chip Carriers (FK),and Standard Plastic (N) and Ceramic (J)DIPs.

The absolute maximum ratings of the SN54173J can be summarized as:(1)supply voltage,VCC:-0.5 to 7V; (2)input voltage:-0.5 to 5.5V; (3)off-state output voltage:-0.5 to 5.5V(4)storage temperature range:-65 to 150.

The electrical characteristics(Ta=25) of the SN54173J can be summarized as:(1)VIH:2.0V MIN; (2)VIL:0.8v MAX; (3)VIK:-1.5V MAX;(4)VOL:0.4V MAX; (5)ICC:50mA TYP 72mA MAX.If you want to know more information such as the electrical characteristics of SN54173J,please download the datasheet in www.seekdatasheet.com .
