High–Performance Silicon–Gate CMOSThe MC74HCT244A is identical in pinout to the LS244. This
device may be used as a level converter for interfacing TTL or NMOS
outputs to High–Speed CMOS inputs. The HCT244A is an octal
noninverting 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 non–inverted outputs and two active–low
output enables.
The HCT244A is the noninverting version of the HCT240. See also
HCT241. Output Drive Capability: 15 LSTTL Loads TTL NMOS–Compatible Input Levels Outputs Directly Interface to CMOS, NMOS, and TTL Operating V oltage 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: 112 FETs or 28 Equivalent Gates
