DS1628 DS3628 Octal TRI-STATE MOS Drivers
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 minimize input currents The circuit employs
Schottky-clamped
transistors for high speed A NOR gate of two inputs DIS1 and DIS2 controls the TRI-STATE mode
