RD74LVC541B
Octal Buffers / Line Drivers with 3-state Outputs
REJ03D0114-0200 Rev.2.00 Mar. 03, 2005
Description
The RD74LVC541B 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.
