TRI-STATEÉ TTL to MOS Multiplexers/Drivers

General Description 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 la
