THVD15xx 5-V RS-485 Transceivers With ±18-kV IEC ESD Protection
1 Features
•1 Meets or Exceeds the Requirements of the
TIA/EIA-485A Standard
• 4.5 V to 5.5 V Supply Voltage
• Integrated Bus I/O Protection
– ± 30 kV HBM ESD
– ± 18 kV IEC 61000-4-2 ESD Contact
Discharge
– ± 25 kV IEC 61000-4-2 ESD Air-Gap
Discharge
– ± 4 kV IEC 61000-4-4 Electrical Fast Transient
• Extended Operational Common-mode: ± 15 V
• Low EMI 500 kbps and 50 Mbps Data Rates
• Extended Temperature Range: -40°C to 125°C
• Large Receiver Hysteresis for Noise Rejection
• Low Power Consumption
– Low Standby Supply Current: < 1 µA
– Current During Operation: < 1 mA
• Glitch-Free Power-Up/Down for Hot Plug-in
Capability
• Open, Short, and Idle Bus Failsafe
• 1/8 Unit Load Options (Up to 256 Bus Nodes)
• Small-Size VSSOP Packages Save Board Space
or SOIC for Drop-in Compatibility
Each of these devices operates from a single 5-V
supply. The devices in this family feature an extended
common-mode voltage range which makes them
suitable for multi-point applications over long cable
runs.
THVD15xx family of devices is available in small
VSSOP packages for space-constrained applications.
These devices are characterized over ambient free-
air temperatures from –40°C to 125°C.

3 Description
THVD15xx is a family of noise-immune RS-485/RS-
422 transceivers designed to operate in rugged
industrial environments. The bus pins of these
devices are robust to high levels of IEC electrical fast
transients (EFT) and IEC electrostatic discharge
(ESD) events, eliminating the need for additional
system-level protection components.
