The STMicroelectronics M74HC266B1R is a 74HC series Quad 2-input XNOR gate featuring open-drain outputs. This high-speed CMOS device operates over a voltage supply range of 2V to 6V. Each of the four independent circuits accepts two inputs and provides an XNOR logic function. The open-drain output configuration allows for wired-AND functionality and requires external pull-up resistors. Key electrical characteristics include a maximum propagation delay of 15ns at 6V with a 50pF load, a quiescent current of 1µA, and output current capabilities of 5.2mA when low. Input logic levels are specified from 0.5V to 1.8V for low and 1.5V to 4.2V for high. The component is housed in a 14-pin Dual In-line Package (DIP) with a 0.300" pitch and is suitable for through-hole mounting. This device finds application in digital logic, control systems, and signal processing across various industrial and consumer electronics sectors.
