MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC74HC173 Quad 3-State D Flip-Flop with Common Clock and Reset High–Performance Silicon–Gate CMOS N SUFFIX PLASTIC PACKAGE 16 The MC74HC173 is identical in pinout to the LS173. The device inputs are CASE 648–08 compatible with standard CMOS outputs; with pullup resistors, they are 1 compatible with LSTTL outputs. Data, when enabled, are clocked into the four D flip–flops with the rising edge of the common Clock. When either or both of the Output Enable D SUFFIX Controls is high, the outputs are in a high–impedance state. This feature 16 SOIC PACKAGE CASE 751B–05 allows the HC173 to be used in bus–oriented systems. The Reset feature is 1 asynchronous and active high. • Output Drive Capability: 15 LSTTL Loads ORDERING INFORMATION
