DESCRIPTION

The M54/74HC7240, HC7241 and HC7244 are high

speed CMOS OCTAL BUS BUFFERs fabricated in

silicon gate C

MOS technology.

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

complementary G and G inputs. Each control input

PIN CONNECTION

HC7240

HC7241

HC7244

governs four BUS BUFFERs.

The HC7240, HC7241 and HC7244 have the same

pin configuration and function as the HC240, HC241

and HC244 and they have a hysteresis

characteristics with each input so can be used as a

line receiver, etc.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
