3 Description
The AM26LS32Ax and AM26LS33Ax 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.
