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 ±7.0V. The
DS26F32 provides 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.
