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.
