The MC54/74HC244A is identical in pinout to the LS244. The device
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LSTTL outputs.
This octal noninverting buffer/line driver/line receiver is designed to be
used with 3–state memory address drivers, clock drivers, and other
bus–oriented systems. The device has noninverting outputs and two
active–low output enables.
The HC244A is similar in function to the HC240A and HC241A.

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high–impedance cir-
cuit. For proper operation, Vin and
v vVout should be constrained to the
range GND (Vin or Vout) VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
Functional operation should be restricted to the Recommended Operating Conditions.
