The SN74LS366AD is an 8-bit Octal D-type Flip-Flop manufactured by Motorola. It is an asynchronous master-slave D-type flip flop device that features a latch-style design and a common data-enable control line. It functions as a data storage device, using asynchronous master-slave operation to provide reliable state change information for logic systems. The device features a low power consumption, high-speed operation, wide operating voltage and high noise immunity, making it ideal for use in automotive, industrial, and consumer electronic applications. The device also features a guaranteed output transition time of 4ns, and is available in either a standard commercial temperature range or an extended temperature range.
