ISL32277EIRZ-T - Renesas Electronics

Description: These Renesas devices are ±16. 5kV IEC61000-4-2 ESD protected, 3. 0V to 5. 5V powered, quad receivers for balanced communication using the RS-485 and RS-422 standards. Each receiver has low input currents (±200μA), so it presents a 1/4 unit load to the RS-485 bus and allows up to 128 receivers on the bus. The ISL32173E and ISL32177E are high data rate receivers that operate at data rates up to 80Mbps. Their 8ns maximum propagation delay skew (tolerance) ensures excellent part-to-part matching. The ISL32273E
