SN74LS173ANE4 Datasheet PDF - TI

●description

●The ’173 and ’LS173A 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.

●3-State Outputs Interface Directly With System Bus

●Gated Output-Control LInes for Enabling or Disabling the Outputs

●Fully Independent Clock Virtually

●  Eliminates Restrictions for Operating in One of Two Modes:

●    – Parallel Load

●    – Do Nothing (Hold)

●For Application as Bus Buffer Registers

●Package Options Include Plastic

●  Small-Outline (D) Packages, Ceramic Flat W) Packages, Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic (J) DIPs
