description
The SN74ALS819 and SN74ALS29818 are 8-bit
pipeline registers each with an on-chip shadow
register. They are for use in applications such as
write control store and shadow register diagnos-
tics.
The output registers of the ’ALS819 and
’ALS29818 are loaded in parallel from either the
I/O port (DQ0 – DQ7) or the shadow register. The
shadow register of the ’ALS2981A 8 can be
loaded serially or from either the I/O port (Y0 – Y7)
or the pipeline register. The ’ALS819 shadow
register can be loaded serially or from the I/O port
(DQ0 – DQ7). In addition, the ’ALS819 provides a
Parity-Even (PE) output, which monitors parity of
the output register. Operation of these devices is
controlled by the Mode and SDI inputs as shown
in the function table.
The SN74ALS819 and SN74ALS29818 are
characterized for operation from 0
°C to 70°C.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.
