description

The SN55LBC174 is composed of monolithic

quadruple differential line drivers with 3-state

outputs. This device is designed to meet the

requirements of the Electronics Industry

Association (EIA) Standard RS-485 and is

20 19

1,2EN

optimized

for

balanced

multipoint

bus

3,4EN

transmission at data rates up to and exceeding 10

million bits per second. Each driver features wide

positive and negative common-mode output

voltage

ranges,

current

limiting,

and

thermal-shutdown protection making it suitable

for party-line applications in noisy environments.

This device is designed using LinBiCMOS ,

facilitating ultra-low power consumption and

inherent robustness.

NC – No internal connection

The SN55LBC174 provides positive and negative-current limiting and thermal shutdown for protection from line

fault conditions on the transmission bus line. This device offers optimum performance when used with the

SN55LBC173quadruple line receiver. The SN55LBC174 is available in the 16-pin CDIP package (J), the 16-pin

CPAK (W), or the 20-pin LCCC package (FK).

The SN55LBC174 is characterized for operation over the military temperature range of –55°C to 125°C.
