AEIC-2631-S16
Quad Differential Line Driver*
Data Sheet
Description
These line drivers are similar to the popular 26LS31 device,
but without the enable function. They provide the addi-
tional supply voltage range necessary for use in many
industrial control applications. AEIC-2631-S16 not only
supports RS-422A, but use of supplies up to 30 V. Output
voltage swings up to VCC -2 V are typical. The outputs are
protected against shorts to ground by a two-fold scheme
of current limiting and thermal shutdown.
Thermal shutdown is accomplished by monitoring
junction temperature and comparing this to a band gap
reference on chip. Input hysteresis of about 0.5 V provides
good noise margin, even in noisy industrial control envi-
ronments. Input to output propagation delays of less than
200 ns are typical for rising and falling edges of the input
waveform, measured to the zero crossing of the differen-
tial outputs.
This part is available in 16L SOIC (Pb-free) package.
