DS26F32C DS26F32M
Quad Differential Line Receiver
General Description
The DS26F32 is a quad differential line receiver designed to
meet the requirements of EIA Standards RS-422 and RS-
423 and Federal Standards 1020 and 1030 for balanced
and unbalanced digital data transmission
The DS26F32 offers improved performance due to the use
of state-of-the-art L-FAST bipolar technology The L-FAST
technology allows for higher speeds and lower currents by
utilizing extremely short gate delay times Thus the
DS26F32 features lower power extended temperature
range and improved specifications
The device features an input sensitivity of 200 mV over the
input common mode range of g7 0V The DS26F32 pro-
vides an enable function common to all four receivers and
TRI-STATE outputs with 8 0 mA sink capability Also a
fail-safe input output relationship keeps the outputs high
when the inputs are open
The DS26F32 offers optimum performance when used with
the DS26F31 Quad Differential Line Driver
