DS26C32ATMX/NOPB – NATIONAL SEMICONDUCTOR

The DS26C32ATMX/NOPB is a quad differential line receiver integrated circuit manufactured by Texas Instruments (formerly National Semiconductor). Housed in a 16-pin SOIC package, this device conforms to the EIA-422 (RS-422) and EIA-485 (RS-485) standards for balanced data transmission. It features four independent receiver channels, each converting differential input signals to single-ended TTL/CMOS compatible outputs. The receiver inputs incorporate high input impedance and enhanced noise immunity, ensuring reliable data reception in electrically noisy environments. The /NOPB suffix indicates a lead-free finish, compliant with RoHS directives. Propagation delay is typically in the nanosecond range, enabling high-speed data communication. The device operates from a single 5V supply and incorporates built-in hysteresis to prevent output oscillation due to slowly changing input signals or noise.
