Octal 3-State Inverting Buffer/
Line Driver/Line Receiver with
LSTTL-Compatible Inputs
High–Performance Silicon–Gate CMOS
be used as a level converter for interfacing TTL or NMOS outputs to
High–Speed CMOS inputs. The HCT240A is an octal inverting buffer line
driver line receiver designed to be used with 3–state memory address
drivers, clock drivers, and other bus–oriented systems. The device has
inverting outputs and two active–low output enables.
