High–Performance Silicon–Gate CMOS
The MC54/74HCT244A 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 Voltage Range: 4.5 to 5.5 V
Low Input Current: 1
