DS26F32M

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

an enable function common to all four receivers and

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.
