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.
