DESCRIPTION

The M54/74HC240, HC241 and HC244 are high

speed CMOS OCTAL BUS BUFFERs fabricated in

silicon gate C²MOS technology.

complementary G and G inputs. Each control input

governs four BUS BUFFERs.

These devices are designed to be used with 3 state

memory address drivers, etc. All inputs are

equipped with protection circuits against static

discharge and transient excess voltage.

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

(active low output

control) input, and
