AM26LV31CDR

The AM26LV31CDR is a BiCMOS quadruple differential line driver with 3-state outputs, designed for balanced-bus transmission at switching rates up to 32 MHz. It operates from a single 3.3V supply and accepts 5V logic inputs, making it suitable for mixed-voltage systems.

Key electrical specifications include a maximum data rate of 32 Mbps, typical propagation delay of 8 ns, pulse skew of 500 ps, and differential output voltage of 1.5 V into a 100 Ω load. The device features controlled rise and fall times of 3 ns typical, ultra-low DC power dissipation of 0.3 mW maximum, and a typical supply current of 100 µA. It supports half-duplex communication with RS-422 and RS-485 protocols, and can drive up to 32 nodes on a bus. Fault protection voltage and common-mode range are both -7 V to 7 V.

The device is packaged in a 16-SOIC (9.9 mm × 6 mm) surface-mount package, with a gull-wing lead style. It is pin-to-pin compatible with the AM26C31, AM26LS31, and MB571, offering a low-voltage upgrade path. Operating temperature range is 0°C to 70°C.
