description
The ’ACT11853 is an 8-bit to 9-bit parity
transceiver designed for two-way communication
between data buses. When data is transmitted
from the A bus to the B bus, a parity bit is
generated. When data is transmitted from the B
bus to the A bus with its corresponding parity bit,
the ERR output will indicate whether or not an
error in the B data has occurred. The output
enable inputs OEA and OEB can be used to
disable the device so that the buses are effectively
isolated.
A 9-bit parity generator/checker generates a
parity-odd output (PARITY) and monitors the
parity of the I/O ports with an open-drain parity
error flag (ERR). ERR can be either passed, sampled, stored, or cleared from the latch using the LE and CLR
control inputs. The error flag register is cleared with a low pulse on the CLR input. When both OEA and OEB
are low, data is transferred from the A bus to the B bus and inverted parity is generated. Inverted parity is a forced
error condition that gives the designer more system diagnostic capability.
The 54ACT11853 is characterized for operation over the full military temperature range of – 55
°
C to 125
°
C.
The 74ACT11853 is characterized for operation from – 40
°
C to 85
°
C.
