Linear Technology recently introduced the LTC2876 and LTC2877, which are high-voltage-tolerant RS-485 transceivers targeted for PROFIBUS-DP (decentralized periphery) networks. Whether transmitting, receiving, in standby or powered off, the LTC2876 and LTC2877 tolerate ±60 V on their bus pins, eliminating common damage due to transmission line faults.
LTC2876 and LTC2877 features and specs:
- Protected from overvoltage line faults to ±60 V
- ±52-kV ESD Interface Pins, ±15 kV on all other pins
- Extended common mode range: ±25 V
- 1.65-to-5.5-V Logic supply pin for flexible digital interfacing (LTC2877)
- 5-V Supply can operate down to 3 V for low-power, low-swing applications
- Wide operating temperature range: –40°C to 125°C
- Available in small DFN and MSOP packages
