RD74LVC540B
Octal Buffers / Line Drivers with 3-state Outputs
REJ03D0113–0200
Rev.2.00
Mar. 03, 2005
Description
The RD74LVC540B 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.

VCC = 1.65 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 ±4 mA (@VCC = 1.65 V)
±8 mA (@VCC = 2.3 V)
±12 mA (@VCC = 2.7 V)
±24 mA (@VCC = 3.0 V to 5.5 V)
