DESCRIPTION
The M54/74HC240, HC241 and HC244 are high
speed CMOS OCTAL BUS BUFFERs fabricated in
silicon gate C
They have the same high speed performance of
LSTTL combined with true CMOS low power
consumption.
The designer has a choise of select combination of
inverting and non-inverting outputs, symmetrical G
