Overview
Description
The RAA7884QR is a ±16.5kV IEC61000-4-2 ESD protected, 3.0V to 5.5V powered, quad receiver designed for balanced communication using the RS-485 and RS-422 standards. With low input currents (±200µA), the receiver presents a 1/4 unit load to the RS-485 bus and allows up to 128 receivers on the bus.
The RAA7884QR is a high data rate receiver that operates at data rates up to 80Mbps. With an 8ns maximum propagation delay skew (tolerance), it ensures excellent part-to-part matching. The receiver outputs are tri-statable and include a hot plug feature to keep them disabled during power-up and power-down.
