description
The AM26LV32, BiCMOS, quadruple, differential line receiver with 3-state outputs is designed to be similar to
TIA/EIA-422-B and ITU Recommendation V.11 receivers with reduced common-mode voltage range due to
reduced supply voltage.
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 receiver high input impedance and 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 circuited, the outputs are in the high logic state. This device
is designed using the Texas Instruments (TI) proprietary LinIMPACT-C60 technology, facilitating ultra-low
power consumption without sacrificing speed.
This device offers optimum performance when used with the AM26LV31 quadruple line drivers.
The AM26LV32C is characterized for operation from 0°C to 70°C.
