General Description
The DS16149/DS36149 and DS16179/DS36179are Hex
MOS driverswith outputs designedto drive large capacitive
loadsupto500pF associatedwith MOS memory systems.
PNP input transistorsare employedto reduce input currents
allowingthe large fan-outto these drivers neededin memo- systems.The circuithas Schottky-clamped transistorlog- forminimum propagation delay,anda disable controlthat
placesthe outputsinthe logic‘‘1’’ state (see truth table).
Thisis especially usefulin MOS RAM applications wherea
setof address lineshastobeinthe logic‘’1’’ state during
refresh.
The DS16149/DS36149hasa15X resistorin series with
the outputsto dampen transientscausedbythe fast-switch-
ing output.The DS16179/DS36179hasa directlow imped-
ance outputforuse withor withoutan external resistor.
