Overview
The AM26LV32CD, produced by Texas Instruments, is a BiCMOS, quadruple differential line receiver with 3-state outputs. This device is designed to be similar to TIA/EIA-422-B and ITU Recommendation V.11 receivers but with a reduced common-mode voltage range due to the lower supply voltage. It is optimized for balanced bus transmission at switching rates up to 32 MHz, making it suitable for high-speed data transmission applications.
The device features an enable function common to all four receivers, offering a choice of active-high or active-low inputs. The 3-state outputs allow direct connection to a bus-organized system, and each receiver has high input impedance, input hysteresis for noise immunity, and input sensitivity of ±200 mV over a common-mode input voltage range from −0.3 V to 5.5 V.
