MC74HCT244A
Octal 3State Noninverting
Buffer/Line Driver/
Line Receiver with
LSTTLCompatible Inputs
HighPerformance SiliconGate CMOS
The MC74HCT244A is identical in pinout to the LS244. This
device may be used as a level converter for interfacing TTL or NMOS
outputs to HighSpeed CMOS inputs. The HCT244A is an octal
noninverting buffer line driver line receiver designed to be used with
3state memory address drivers, clock drivers, and other busoriented
systems. The device has noninverted outputs and two activelow
output enables.
The HCT244A is the noninverting version of the HCT240. See
also HCT241.
