DESCRIPTION:
The IDT54/74FCT833s are high-performance bus
transceivers designed for two-way communications. They
each contain an 8-bit data path from the R (port) to the T (port),
an 8-bit data path from the T (port) to the R (port), and a 9-bit
parity checker/generator. The error flag can be clocked and
stored in a register and read at the
ERR
output. The clear
(
CLR
) input is used to clear the error flag register.
The output enables
OE
T
and
OE
R
are used to force the
port outputs to the high-impedance state so that the device
can drive bus lines directly. In addition,
OE
R
and
OE
T
can be
used to force a parity error by enabling both lines
simultaneously. This transmission of inverted parity gives the
designer more system diagnostic capability. The devices are
specified at 48mA and 32mA output sink current over the
commercial and military temperature ranges, respectively.
