High–Performance Silicon–Gate CMOSThe MC74HCT240A is identical in pinout to the LS240. This device may
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.
The HCT240A is the inverting version of the HCT244. See also HCT241. Output Drive Capability: 15 LSTTL Loads TTL NMOS–Compatible Input Levels Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 4.5 to 5.5 V Low Input Current: 1 μA In Compliance with the Requirements Defined by JEDEC Standard
No. 7A Chip Complexity: 110 FETs or 27.5 Equivalent Gates
