QUAD DIFFERENTIAL LINE DRIVER
(Pin compatible with 26LS31 in applications which
do not require an enable function.)
• Supply Voltage Range 4.75V to 30V
• Operation to 800KHz
• CMOS and TTL Compatible Inputs
• Outputs RS-422A Compatible
• High Impedance Buffered Inputs with
• Outputs short circuit protected
• 70mA peak SINK current
• Outputs Protected by Thermal Shut-Down
• MSL level 2
These line drivers are similar to the popular 26LS31 device, but without the enable function. They provide the
additional supply voltage range necessary for use in many industrial control applications. Outputs are compatible
with RS-422A, but they allow use of supplies up to 30V. Output voltage swings up to VCC-2V 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 0.5V provides good noise margin, even in noisy industrial control environments. Input to
output propagation delays of less than 200ns are typical for rising and falling edges of the input waveform,
measured to the zero crossing of the differential outputs.
