SN74ABT16853 双路 8 位至 9 位奇偶校验收发器
SN74ABT16853 描述
The 'ABT16853 dual 8-bit to 9-bit parity transceivers are designed for 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 open-collector parity-error (
) output indicates whether or not an error in the B data has occurred. The output-enable (
and 
) inputs can be used to disable the device so that the buses are effectively isolated. The 'ABT16853 provide true data at the outputs.
A 9-bit parity generator/checker generates a parity-odd (PARITY) output and monitors the parity of the I/O ports with the flag. The parity-error output can be passed, sampled, stored, or cleared from the latch using the latch-enable (
) and clear (
) control inputs.
