TRI-STATE TTL To MOS Multiplexers/Drivers

The DS1648/DS3648 and DS1678 DS3678 are quad 2-in- put 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 reduced. The circuit employs Schottky- clamped Transistors for high speed and TRI-STATE outputs for bus operation. The DS1648/DS3648 has a 15X resistor in series with the outputs to dampen transients caused by the fast-switching output. The DS1678 DS3678 has a direct, low impedance output for use with or without an external resistor. By National Semiconductor Corporation
