Description
General part information
74ABT16833 Series
The 'ABT16833 consist of two noninverting 8-bit to 9-bit parity bus transceivers and are designed for communication between data buses. For each transceiver, when data is transmitted from the A bus to the B bus, an odd-parity bit is generated and output on the parity I/O pin (1PARITY or 2PARITY). When data is transmitted from the B bus to the A bus, 1PARITY (or 2PARITY) is configured as an input and combined with the B-input data to generate an active-low error flag if odd parity is not detected.
The error (1or 2) output is configured as an open-collector output. The B-to-A parity-error flag is clocked into 1(or 2) on the low-to-high transition of the clock (1CLK or 2CLK) input. 1(or 2) is cleared (set high) by taking the clear (1or 2) input low.
The output-enable (and) inputs can be used to disable the device so that the buses are effectively isolated. When bothandare 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.
