SN74BCT29854 8 位至 9 位奇偶校验收发器
SN74BCT29854 描述
The SN74BCT29854 is an 8-bit to 9-bit parity transceiver designed for asynchronous communication between data buses. When data is transmitted from the A to B bus, a parity bit is generated. When data is transmitted from the B to A bus with its corresponding parity bit, the parity-error (
) output will indicate whether or not an error in the B data has occurred. The output-enable (
, 
) inputs can be used to disable the device so that the buses are effectively isolated.
A 9-bit parity generator/checker generates a parity-odd (PARITY) output and monitors the parity of the I/O ports with an open-collector parity-error () flag. can be either passed, sampled, stored, or cleared from the latch using the latch-enable (
) and clear (
) control inputs.
