Overview
The 74LVC1G74DP is a single positive edge triggered D-type flip-flop produced by Nexperia USA Inc. This component features individual data (D), clock (CP), set (SD), and reset (RD) inputs, along with complementary Q and Q outputs. It is designed to operate in mixed 3.3 V and 5 V environments, making it versatile for various electronic designs. The device includes Schmitt-trigger action at all inputs, enhancing its tolerance to slower input rise and fall times. Additionally, it is fully specified for partial power-down applications using IOFF, which prevents potentially damaging backflow current when the device is powered down.
