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. When the inputs are open, the fail-safe

design makes sure 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.
