and unbalanced digital data transmission. The
enable function is common to all four receivers		2B	GND	NC	3B	3A
and offers a choice of active-high or active-low
input. The 3-state outputs permit connection	NC ± No internal connection
directly to a bus-organized system. Fail-safe
design ensures that, if the inputs are open, the
outputs are always 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 AM26LS32AM and AM26LS33AM are characterized for operation over the full military temperature range of ±55°C to 125°C.

²Stresses beyond those listed under ªabsolute maximum ratingsº may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under ªrecommended operating conditionsº is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. All voltage values, except differential voltages, are with respect to the network ground terminal.

2.Differential voltage values are at the noninverting (A) input terminals with respect to the inverting (B) input terminals.

3.The package thermal impedance is calculated in accordance with JESD 51.
