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.
