HD74LV540A - Octal Inverted Buffers / Drivers with 3-state Outputs

General Description

The HD74LV540A has eight inverter drivers with three state outputs in a 20 pin package.

When OE1 and OE2 is low level, this drivers set up output is enable.

Key Features

  • VCC = 2.0 V to 5.5 V operation All inputs VIH (Max. ) = 5.5 V (@VCC = 0 V to 5.5 V) All outputs VO (Max. ) = 5.5 V (@VCC = 0 V) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.3 V (@VCC = 3.3 V, Ta = 25°C) Output current ±8 mA (@VCC = 3.0 V to 3.6 V), ±16 mA (@VCC = 4.5 V to 5.5 V) Function Table Inputs OE1 L L H X Note: H: L: X: Z: High level Low level Immaterial High impedance OE2 L L X H A L H X.

HD74LV540A Octal Inverted Buffers / Drivers with 3-state Outputs ADE-205-277 (Z) 1st Edition April 1999 Description The HD74LV540A has eight inverter drivers with three state outputs in a 20 pin package. When OE1 and OE2 is low level, this drivers set up output is enable. Low-voltage operation is suitable for batterypowered products (e.g., notebook computers), and the low-power consumption extends the battery life.
