DS1649/DS3649/DS1679/DS3679 Hex TRI-STATE TTL  
É
to MOS Drivers  
General Description  
The DS1649/DS3649 and DS1679/DS3679 are Hex  
TRI-STATE MOS drivers with outputs designed to drive  
large capacitive loads up to 500 pF associated with MOS  
memory systems. PNP input transistors are employed to re-  
duce input currents allowing the large fan-out to these driv-  
ers needed in memory systems. The circuit has Schottky-  
clamped transistor logic for minimum propagation delay,  
and TRI-STATE outputs for bus operation.  
output. The DS1679/DS3679 has a direct low impedance  
output for use with or without an external resistor.
