3Q 7 15 3D The ’173 and ’LS173A 4-bit registers include 4Q 8 14 4D 9 10 11 12 13 D-type flip-flops featuring totem-pole 3-state CLK GND NC G1 G2 outputs capable of driving highly capacitive or relatively low-impedance loads.
The high-impedance third state and increased NC – No internal connection 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.
Up to 128 of the SN74173 or SN74LS173A outputs can be connected to a common bus and still drive two Series 54/74 or 54LS/74LS TTL normalized loads, respectively.
