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 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.
