Overview
The 74LVC273DB,112 is an octal D-type flip-flop with a positive-edge trigger, manufactured by Nexperia (previously part of NXP Semiconductors). This integrated circuit features clock (CP) and master reset (MR) inputs, making it versatile for various digital logic applications. The device is designed to operate in mixed 3.3 V and 5 V environments, with inputs that can be driven from either voltage level. It is notable for its Schmitt-trigger action at all inputs, which enhances tolerance to slower input rise and fall times.
