DS1678, DS1648, TRI-STATE TTL to MOS Multiplexers/Drivers
The DS1648 DS3648 and DS1678 DS3678 are quad 2-input multiplexers with TRI-STATE outputs designed to drive the large capacitive loads (up to 500 pF) associated with MOS memory systems A PNP input structure is employed to minimize input currents so that driver loading in large memory systems is reduc
