The '138 is a decoder (demultiplexer).  What you are looking
for is more likely considered a hammer driver.  The two
functions tend not to coexist; if you wanted a low-side
driver that could handle 8 loads, you would likely be looking
to drive any *combination* of those loads... an "octal
driver".

You can probably find something automotive that would give you
8 such outputs in a package (though 8@2A would likely be
pushing the power dissipation of a normal package) -- but it
would likely have an I2C or SPI interface, requiring you
to do the "decoding"/selection elsewhere.
