Overview
The 74LVC1G74GT is a single positive edge triggered D-type flip-flop with individual data (D), clock (CP), set (SD), and reset (RD) inputs, and complementary Q and Q outputs. This device is part of the 74LVC family from Nexperia (formerly part of NXP Semiconductors), known for its low voltage CMOS logic. It is designed to operate in a wide supply voltage range from 1.65 V to 5.5 V, making it versatile for various applications. The flip-flop stores data at the D-input that meets the set-up and hold time requirements on the LOW-to-HIGH clock transition, and it appears at the Q output. The device also features Schmitt-trigger action at all inputs, enhancing noise immunity and tolerance to slower input rise and fall times.
