DS16149 DS36149 DS16179 DS36179 Hex MOS Drivers
General Description
The DS16149 DS36149 and DS16179 DS36179 are Hex
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 reduce input currents
allowing the large fan-out to these drivers needed in memo-
ry systems The circuit has Schottky-clamped transistor log-
ic for minimum propagation delay and a disable control that
places the outputs in the logic ‘‘1’’ state (see truth table)
This is especially useful in MOS RAM applications where a
set of address lines has to be in the logic ‘’1’’ state during
refresh
The DS16149 DS36149 has a 15
the outputs to dampen transients caused by the fast-switch-
ing output The DS16179 DS36179 has a direct low imped-
ance output for use with or without an external resistor
