MOTOROLA SEMICONDUCTOR TECHNICAL DATA Low-Voltage CMOS Octal D-Type Flip-Flop With 5V-Tolerant Inputs and Outputs (3-State, Non-Inverting) The MC74LCX374 is a high performance, non–inverting octal D–type flip–flop operating 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 MC74LCX374 inputs to be safely driven from 5V devices. The MC74LCX374 consists of 8 edge–triggered flip–flops with individual D–type inputs and 3–state true outputs. The buffered clock and buffered Output Enable (OE) are common to all flip–flops. The eight flip–flops will store the state of individual D inputs that meet the setup [ ... ]
