HD74LVC540A
Octal Buffers / Line Drivers with 3-state Outputs
ADE-205-114B(Z)
3rd Edition
December 1996
Description
The HD74LVC540A has eight inverter 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 VOUT (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 output current ±24 mA (@VCC = 3.0 V to 5.5 V)
