74F3040中文资料飞利浦数据手册PDF规格书

DESCRIPTION

The 74F3040 is a high current Line Driver composed of two 4-input NAND gates. It has been designed to deal with the transmission line effects of PC boards which appear when fast edge rates are used.

The drive capability of the 74F3040 is 67mA source and 160mA sink with a VCC as low as 4.5V. This guarantees incident wave switching with VOH not less than 2.0V and VOL not more than 0.8V while driving impedances as low as 30Ω. This is applicable with any combination of outputs using continuous duty.

FEATURES

• 30Ω line driver

• 160mA output drive capability in the Low state

• 67mA output drive capability in the High state

• High speed

• Facilitates incident wave switching

• 3nh lead inductance each on VCC and GND when both side pins are used
