The DS8922MX/NOPB is an integrated circuit (IC) component primarily designed as a line driver/receiver for TIA/EIA-485 or TIA/EIA-422 communication bus systems. It belongs to Texas Instruments' family of high-speed differential line drivers and receivers.
Key features of the DS8922MX/NOPB include a wide operating voltage range of 4.5V to 5.5V, making it compatible with various system power supplies. The IC has a high common-mode range of -7V to +12V, enabling reliable operation even in noisy environments. It can handle data rates up to 16Mbps, making it suitable for high-speed data transmission.
The DS8922MX/NOPB incorporates three-state outputs that can be easily enabled or disabled using the output enable (OE) control pin. This feature helps in controlling the direction of data flow, allowing the IC to function as both a driver and a receiver. It also supports fail-safe circuitry, which ensures a high receiver output when the bus is idle or not connected, preventing ambiguity in the received data.
With built-in thermal shutdown protection, the DS8922MX/NOPB safeguards itself against excessive heat and potential damage. Moreover, it has ESD protection on the bus pins, allowing the IC to withstand electrostatic discharges up to ±15kV
