description

The SN75LBC184 and SN65LBC184 are differ-

ential 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.

± 1/2 V

The SN75LBC184 and SN65LBC184 can with-

stand overvoltage transients of 400 W peak

(typical). The conventional combination wave

called out in CEI IEC 1000-4-5 simulates the

overvoltage transient and models a unidirectional

surge caused by overvoltages from switching and

secondary lightning transients.
