MOTOROLA SEMICONDUCTOR TECHNICAL DATA Low-Voltage CMOS Dual D-Type Flip-Flop With 5V-Tolerant Inputs The MC74LCX74 is a high performance, dual D–type flip–flop with asynchronous clear and set inputs and complementary (O, O) outputs. It operates from a 2.7 to 3.6V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5V allows MC74LCX74 inputs to be safely driven from 5V devices. The MC74LCX74 consists of 2 edge–triggered flip–flops with individual D–type inputs. The flip–flop will store the state of individual D inputs, that meet the setup and hold time requirements, on the LOW–to–HIGH Clock (CP) transition.
