They have the same high speed performance of LSTTL combined with true CMOS low power consumption. The M54/75HC4049 is an inverting buffer, while the M54/74HC4050 is a non-inverting buffer. The internal circuit is composed of 3 stage or 2stage inverters, which provides high noise immunity and a stable output. Input protection circuits are different from those of the high speed CMOS IC’s. The VCC side diodes are designed to allow logiclevel convertion from high-level voltages (up to 15 V) to low-level voltages.
