DESCRIPTION
The 74ABT853 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT853 is an octal transceiver with a parity
generator/checker and is intended for bus–oriented applications.
When Output Enable A (OEA) is High, it will place the A outputs in a
high impedance state. Output Enable B (OEB) controls the B
outputs in the same way.
The parity generator creates an odd parity output (PARITY) when
OEB is Low. When OEA is Low, the parity of the B port, including
the PARITY input, is checked for odd parity. When an error is
detected, the error data is sent to the input of a latch. The error data
can then be passed, stored, cleared, or sampled depending on the
ENABLE and CLEAR control signals.
If both OEA and OEB are Low, data will flow from the A bus to the B
bus and the part is forced into an error condition which creates an
inverted PARITY output. This error condition can be used by the
designer for system diagnostics.
