HD74LVC541A

Octal Buffers / Line Drivers with 3-state Outputs

ADE-205-115B(Z)

3rd Edition

December 1996

Description

The HD74LVC541A has eight line drivers with three state outputs in a 20 pin package. When G1 and G2
is low level, this drivers set up output is enable. Low voltage and high speed operation is suitable at the
battery drive product (note type personal computer) and low power consumption extends the life of a
battery for long time operation.

Features

• VCC = 2.0 V to 5.5 V

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

• All outputs V

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

(Max.) = 5.5 V (@VCC = 0 V or output off state)
