DS1649 DS3649 DS1679 DS3679 Hex TRI-STATE TTL
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
The DS1649 DS3649 has a 15X resistor in series with the
outputs to dampen transients caused by the fast-switching
TRI-STATE is a registered trademark of National Semiconductor Corp
output The DS1679 DS3679 has a direct low impedance
output for use with or without an external resistor
