description/ordering information

The AM26C32 is a quadruple differential line

receiver for balanced or unbalanced digital data

transmission. The enable function is common to

all four receivers and offers a choice of active-high

or active-low input. The 3-state outputs permit

connection directly to a bus-organized system.

Fail-safe design specifies that if the inputs are

open, the outputs always are high.

The AM26C32 devices are manufactured using a BiCMOS process, which is a combination of bipolar and

CMOS transistors. This process provides the high voltage and current of bipolar with the low power of CMOS

to reduce the power consumption to about one-fifth that of the standard AM26LS32, while maintaining ac and

dc performance.

The AM26C32C is characterized for operation from 0°C to 70°C. The AM26C32I is characterized for operation

from −40°C to 85°C. The AM26C32Q is characterized for operation from −40°C to 125°C. The AM26C32M is

characterized for operation over the full military temperature range of −55°C to 125°C.
