Low−Voltage CMOS Dual D−Type Flip−Flop With 5 V−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 2.3 to 3.6 V 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 5.5 V allows MC74LCX74 inputs to be safely driven from 5.0 V devices.
