description
The AM26C32C, AM26C32I, and AM26C32M are
quadruple differential line receivers 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 are always high.
The AM26C32 is 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.
