description

The SN55ALS195 and SN75ALS195 are four

differential line receivers with 3-state outputs

designed using advanced low-power Schottky

technology. This technology provides combined

improvements in die design, tooling production,

and wafer fabrication, which in turn, provide lower

power consumption and permit much higher data

throughput than other designs. The devices meet

the specifications of ANSI Standards EIA/

TIA-422-B and EIA/TIA-423-A and ITU Recom-

mendations V.10 and V.11. The 3-state outputs

permit direct connection to a bus-organized

system with a fail-safe design that ensures the

outputs will always be high if the inputs are open.

The devices are optimized for balanced multipoint bus transmission at rates up to 20 megabits per second. The

input features high input impedance, input hysteresis for increased noise immunity, and an input sensitivity of

±200 mV over a common-mode input voltage range of ±7 V. The devices also feature an active-high enable

function for each of two receiver pairs. The SN55ALS195 and SN75ALS195 are designed for optimum

performance when used with the SN55ALS194 and SN75ALS194 quadruple differential line drivers.

The SN55ALS195 is characterized for operation over the full military temperature range of – 55

°C to 125°C. The

SN75ALS195 is characterized for operation from 0

°C to 70°C.
