Product Overview
The SN74LV374ATPW from Texas Instruments is an octal D-type flip-flop with 3-state outputs, designed for 2-V to 5.5-V VCC operation. It features edge-triggered flip-flops that store data on the rising edge of the clock (CLK) input. The 3-state outputs are controlled by the output enable (OE) input, allowing for bus-oriented applications. This device is ideal for driving high-capacitance loads while maintaining low power consumption.
