3 Description

The AM26C32 device 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 busorganized

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.
