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.
