M74HC244M1R中文资料意法半导体数据手册PDF规格书

DESCRIPTION

The 74HC244 is an advanced high-speed CMOS OCTAL BUS BUFFER (3-STATE) fabricated with silicon gate C2MOS 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.

■ HIGH SPEED: tPD = 10ns (TYP.) at VCC = 6V

■ LOW POWER DISSIPATION: ICC = 4µA(MAX.) at TA=25°C

■ HIGH NOISE IMMUNITY: VNIH = VNIL = 28 VCC (MIN.)

■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 6mA (MIN)

■ BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL

■ WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V

■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 244
