The MAX9157 is a quad bus LVDS (BLVDS) transceiver for heavily loaded, half-duplex multipoint buses.
The MAX9157 quad‑bus LVDS (BLVDS) transceiver is designed for heavily loaded, half‑duplex multipoint buses. It operates from a single 3.3 V supply, draws 80.9 mA with drivers enabled, and includes a fail‑safe circuit that forces the receiver output high when inputs are open, shorted, or terminated.
The device is offered in 5 mm × 5 mm 32‑pin QFN and TQFP packages, supports up to 200 Mbps data rates, and features 52 mV input hysteresis, 7.2 pF maximum bus‑load capacitance, and a -40 °C to +85 °C operating temperature range.
| Supply Current (Drivers Enabled) | 80.9 mA |
|---|---|
| Supply Current (Drivers Disabled) | 22.7 mA |
| Operating Temperature Range | -40 °C to +85 °C |
| Package Options | 32‑pin QFN (5 mm × 5 mm) or 32‑pin TQFP (5 mm × 5 mm) |
| Input Hysteresis | 52 mV |
It operates from a single 3.3 V supply.
The receiver output goes high when the differential inputs are open, undriven and shorted, or undriven and terminated.
