HD74LVC541A
Octal Buffers / Line Drivers with 3-state Outputs
REJ03D0359–0500Z
(Previous ADE-205-115B (Z))
Rev.5.00
Jul. 28, 2004
Description
The HD74LVC541A 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.
