CD74HC173E Datasheet PDF - TI

●The CD74HC173E is a quad D-type Flip-flop with 3-state outputs. It is fabricated with silicon gate CMOS technology. It possesses the low power consumption of standard CMOS Integrated circuits and can operate at speeds comparable to the equivalent low power Schottky devices. The buffered outputs can drive 15 LSTTL loads. The large output drive capability and three-state feature make these parts ideally suited for interfacing with bus lines in bus oriented systems. The four D-type flip-flops operate synchronously from a common clock. The outputs are in the three-state mode when either of the two output disable pins are at the logic "1, level. The input enables allow the flip-flops to remain in their present states without having to disrupt the clock If either of the 2 input ENABLES are taken to a logic "1" level, the Q outputs are fed back to the inputs, forcing the flip-flops to remain in the same state. Reset is enabled by taking the MR input to a logic "1" level.
