DESCRIPTION

The AM26LS33A is a quadruple differential line receiver 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 AM26LS33, the AM26LS33A incorporates 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 AM26LS33A is characterized for operation over the temperature range of –55°C to 125°C.
