SN65HVD1781QDRQ1

The SN65HVD1781QDRQ1 is a RS-485 Fault-protected Transceiver designed to survive over-voltage faults such as direct shorts to power supplies, mis-wiring faults, connector failures, cable crushes and tool mis-applications. It is also robust to ESD events, with high levels of protection to the human-body-model specification. This device combines a differential driver and a differential receiver, which operate from a single power supply. This port features a wide common-mode voltage range, making the device suitable for multipoint applications over long cable runs. This device is pin-compatible with the industry-standard SN75176 transceiver, making them drop-in upgrades in most systems. This device is fully compliant with ANSI TIA/EIA 485-A with a 5V supply and can operate with a 3.3V supply with reduced driver output voltage for low-power applications.

• Failsafe receiver (bus open, bus shorted and bus idle)

• Reduced unit load for up to 320 nodes
• ±16kV HBM protection on bus pins
• 1μA Maximum low standby supply current
• 4mA Quiescent during operation (ICC)
• 1Mbps Maximum signalling rate
• Green product and no Sb/Br
