DESCRIPTIONThe 74HC244 is an advanced high-speed CMOS
OCTAL BUS BUFFER (3-STATE) fabricated with
silicon gate C2 MOS technology.
G control input governs four BUS BUFFERs.
This device is 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.

AC ELECTRICAL CHARACTERISTICS (CL = 50 pF, Input tr = tf = 6ns)
CAPACITIVE CHARACTERISTICS 1) 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 operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/8 (per circuit)
M74HC2445/10
TEST CIRCUIT CL = 50pF/150pF or equivalent (includes jig and probe capacitance)
R1 = 1KΩ or equivalent
RT = ZOUT of pulse generator (typically 50Ω)
