CD74HC366M

CD74HC366M Description

The CD74HC366M is a high-speed CMOS hex inverting buffer manufactured by Harris Corporation, designed for 2V to 6V operation. This 6-bit logic device features inverting outputs with balanced 7.8mA sink/source current capability, making it suitable for driving moderate loads. Packaged in a 16-SOIC tube, it is optimized for surface-mount applications but is now marked as obsolete, though still relevant for legacy designs. The device belongs to the 74HC series, known for low power consumption and compatibility with TTL levels. Its EAR99 ECCN classification ensures broad exportability for industrial and commercial use.
