Texas Instruments Logic - Buffers, Drivers, Receivers, Transceivers SN74ABT853DWR

The SN74ABT853DWR is an 8-bit to 9-bit parity bus transceiver designed for communication between data buses. It features a parity generator/checker that produces a parity bit during data transmission from the A bus to the B bus, and checks for errors when data is sent back from the B bus to the A bus. The device includes an open-collector parity-error output (ERR) to indicate any errors detected in the B data. This transceiver operates with high-drive outputs, capable of sourcing up to 32 mA and sinking up to 64 mA. It has a high-impedance state during power-up and power-down, ensuring that the device does not interfere with the bus lines. The SN74ABT853DWR is characterized for operation from -40¬8C to 85¬8C and is available in a 24-pin SOIC package. It also provides latch functionality for storing the parity-error flag, enhancing system diagnostics. The device's ESD protection exceeds 2000 V, and it demonstrates robust latch-up performance, exceeding 500 mA. This makes it suitable for applications requiring reliable data transmission with error detection capabilities.
