DS26F32MQML
Quad Differential Line Receivers
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 ±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.
Features
n Input voltage range of ±7.0V (differential or common
mode) ±0.2V sensitivity over the input voltage range
n High input impedance
n Operation from single +5.0V supply
n Input pull-down resistor prevents output oscillation on
unused channels
n TRI-STATE outputs, with choice of complementary
enables, for receiving directly onto a data bus
