DS1678 Overview
Key Specifications
Package: PDIP
Pins: 8
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 large memory systems is reduced The circuit employs Schottkyclamped 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.
