Analog Devices MAX216 Product Info

• Differential Driver/Receiver Compatible with RS-422
• Single-Ended Driver/Receiver Compatible with EIA/TIA-562 and EIA/TIA-232E
• Low, 3mA Max Operational Supply Current
• Low, 30μA Shutdown-Mode Supply Current

The MAX216 transceiver is designed specifically for communicating with AppleTalk™ interfaces. The MAX216 has one differential and one single-ended driver, plus one differential and two single-ended receivers, all of which meet the Apple Talk transceiver specifications.

The single-ended and differential drivers have a ±SV output voltage range when they are active, and have thermal shutdown protection against short circuits. The drivers remain in a high-impedance state when disabled or shut down.

One single-ended receiver is configured as an inverter, and the other is configured as a buffer. The input thresholds of the single-ended receivers are TTL-compatible, but the input voltages can vary between ±7V. The input thresholds of the differential receiver are ±200mV, and have a common-mode range of ±7V.

The MAX216 uses only 3mA max when fully operational. The drivers and receivers are disabled during shutdown mode, when the quiescent current is reduced to only 30μA
