(DS1648 / DS1678) TRI-STATE TTL to MOS Multiplexers/Drivers

DS1648 DS3648 DS1678 DS3678 TRI-STATE TTL to

MOS Multiplexers Drivers

General Description

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

Features

Y TRI-STATE outputs interface directly with system-bus

Y Schottky-clamped for better ac performance

Y PNP inputs to minimize input loading

Y TTL compatible

Y High-speed capacitive load drivers

Y Built-in damping resistor (DS1648 DS3648 only)

Note 1 ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed Except for ‘‘Operating Temperature Range’’

they are not meant to imply that the devices should be operated at these limits The table of ‘‘Electrical Characteristics’’ provides conditions for actual device

operation

Note 2 Unless otherwise specified min max limits apply across the b55 C to a125 C temperature range for the DS1648 and DS1678 and across the 0 C to

a70 C range for the DS3648 and DS3678 All typical values for TA e 25 C and VCC e 5V

Note 3 All currents into device pins shown as positive out of device pins as negative all voltages referenced to ground unless otherwise noted All values shown

as max or min on absolute value basis

Note 4 When measuring output drive current and switching response for the DS1678 and DS3678 a 15X resistor should be placed in series with each output This

resistor is internal to the DS1648 DS3648 and need not be added
