SN54LS173A
Overview
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.
