General Description
The DS1628 DS3628 are octal Schottky memory drivers with TRI-STATE outputs designed to drive high capacitive loads associated with MOS memory systems The drivers’ output (VOH) is specified at 3 4V to provide additional noise immunity required by MOS inputs A PNP input structure is employed to minimi
