DESCRIPTION
The M54/74HC240, HC241 and HC244 are high
speed CMOS OCTAL BUS BUFFERs fabricated in
silicon gate C2MOS technology.
They have the same high speed performance of
LSTTL combined with true CMOS low power
consumption.
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.
The designer has a choise of select combination of
inverting and non-inverting outputs, symmetrical G
(active low output
control) input, and

(*) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load.
(Refer to Test Circuit). Average operting current can be obtained by the following equation. ICC(opr) = CPD •VCC •fIN + ICC/8 (per circuit)
