描述 Description

The HD74LVCZ240A has eight inverter drivers with three state outputs in a 20 pin package. This device is an inverting buffer and has two active low enables (1G and 2G). Each enable independently controls four buffers.

When VCC is between 0 and 1.5 V, the device is in the high impedance state during power up or power down.

Low voltage and high-speed operation is suitable at battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation.

特性 Features

? VCC = 2.7 to 5.5 V

? All inputs VIH (Max) = 5.5 V (@VCC = 0 to 5.5 V)

? All outputs VO (Max) = 5.5 V (@VCC = 0 V or output off state)

? Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)

? Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C)

? High impedance state during power up and power down

? Power off disables outputs, permitting live insertion

? High output current ±24 mA (@VCC = 3.0 to 5.5 V)
