SN65LBC184, SN75LBC184
SLLS236I – OCTOBER 1996 – REVISED JUNE 2015
SNx5LBC184 Differential Transceiver With Transient Voltage Suppression
1 Features
1 Integrated Transient Voltage Suppression
• ESD Protection for Bus Terminals Exceeds:
±30 kV IEC 61000-4-2, Contact Discharge
±15 kV IEC 61000-4-2, Air-Gap Discharge
±15 kV EIA/JEDEC Human Body Model
• Circuit Damage Protection of 400-W Peak
(Typical) Per IEC 61000-4-5
• Controlled Driver Output-Voltage Slew Rates
Allow Longer Cable Stub Lengths
• 250-kbps in Electrically Noisy Environments
• Open-Circuit Fail-Safe Receiver Design
• 1/4 Unit Load Allows for 128 Devices Connected
on Bus
• Thermal Shutdown Protection
• Power-Up and Power-Down Glitch Protection
• Each Transceiver Meets or Exceeds the
Requirements of TIA/EIA-485 (RS-485) and
ISO/IEC 8482:1993(E) Standards
• Low Disabled Supply Current 300 μA Maximum
• Pin Compatible With SN75176
3 Description
The SN75LBC184 and SN65LBC184 devices are
differential data line transceivers in the trade-standard
footprint of the SN75176 with built-in protection
against high-energy noise transients. This feature
provides a substantial increase in reliability for better
immunity to noise transients coupled to the data
cable over most existing devices. Use of these
circuits provides a reliable low-cost direct-coupled
(with no isolation transformer) data line interface
without requiring any external components.
The SN75LBC184 and SN65LBC184 can withstand
overvoltage transients of 400-W peak (typical). The
conventional combination wave called out in IEC
61000-4-5 simulates the overvoltage transient and
models a unidirectional surge caused by overvoltages
from switching and secondary lightning transients.
