AM26LV31INSR

The AM26LV31INSR from Texas Instruments is a BiCMOS quadruple differential line driver with 3-state outputs, optimized for balanced-bus transmission at switching rates up to 32MHz. It operates from a single 3.3V supply, making it suitable for low-voltage applications.

Key electrical specifications include a maximum signaling rate of 32 Mbps, a propagation delay time of 8ns typical, and a pulse skew time of 500ps typical. The device offers high output drive current of ±30 mA and controlled rise and fall times of 3ns typical. Its differential output voltage with a 100Ω load is 1.5V typical. The driver features ultra-low power dissipation, with a DC maximum of 0.3mW and 385mW typical at 32MHz for all channels with no load.

Designed to be similar to TIA/EIA-422-B and ITU Recommendation V.11 drivers, the AM26LV31INSR can accept 5V logic inputs with a 3.3V supply. It serves as a low-voltage, pin-to-pin compatible replacement for older parts like AM26C31, AM26LS31, and MB571. The driver also features high output impedance in the power-off condition and a driver output short-protection circuit.

This component is available in a 16-SOIC surface mount package. The operating temperature range is -45°C to 85°C. Its fault protection is rated from -7V to 7V, with a common-mode range of -7V to 7V, and it supports up to 32 nodes on the bus.
