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.
The device features an input sensitivity of 200mV 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.
