AM26LV32CDR RS-422接口集成电路

3 Description

The AM26LV32 device is a BiCMOS, quadruple

differential line receiver with 3-state outputs, which is

designed to be similar to the TIA/EIA-422-B and ITU

Recommendation V.11 receivers with reduced

common-mode voltage range due to reduced supply

voltage.AM26LV32CDR RS-422接口集成电路

The device is optimized for balanced bus

transmission at switching rates up to 32 MHz. The

enable function is common to all four receivers and

offers a choice of active-high or active-low inputs.

The 3-state outputs permit connection directly to a

bus-organized system. Each device features high

input impedance, input hysteresis for increased noise

immunity, and input sensitivity of ±200 mV over a

common-mode input voltage range from −0.3 V to

5.5 V. When the inputs are open-circuit, the outputs

are in the high logic state

The AM26LV32C is characterized for operation from

0°C to 70°C. The AM26LV32I is characterized for

operation from −45°C to 85°C
