DESCRIPTION
The AM26LS32A and AM26LS33A devices are quadruple differential line receivers for balanced and 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
ensures that, if the inputs are open, the outputs always are high.
Compared to the AM26LS32 and the AM26LS33, the AM26LS32A and AM26LS33A incorporate an additional
stage of amplification to improve sensitivity. The input impedance has been increased, resulting in less loading of
the bus line. The additional stage has increased propagation delay; however, this does not affect
interchangeability in most applications.
The AM26LS32AC and AM26LS33AC are characterized for operation from 0 C to 70 C. The AM26LS32AI is
characterized for operation from –40 C to 85 C. The AM26LS32AM and AM26LS33AM are characterized for
operation over the full military temperature range of –55 C to 125 C.
