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
• V_CC = 2.0 V to 5.5 V
• All inputs V_IH (Max.) = 5.5 V (@V_CC = 0 V to 5.5 V)
• All outputs V_OUT (Max.) = 5.5 V (@V_CC = 0 V or output off state)
• Typical V_OL ground bounce < 0.8 V (@V_CC = 3.3 V, Ta = 25°C)
• Typical V_OH undershoot > 2.0 V (@V_CC = 3.3 V, Ta = 25°C)
• High output current ±24 mA (@V_CC = 3.0 V to 5.5 V)
