DescriptionThe DS26LV32A is a high speed quad differential CMOS receiver that meets the requirements of both TIA/EIA-422-B and ITU-T V.11. The CMOS DS26LV32AT features typical low static ICC of 9 mA which makes it ideal for battery powered and power conscious applications. The TRI-STATE® enables, EN and EN*, allow the device to be active High or active Low. The enables are common to all four receivers.
The receiver output (RO) is guaranteed to be High when the inputs are left open. The receiver can detect signals as low as ±200 mV over the common mode range of ±10V. The receiver outputs (RO) are compatible with TTL and LVCMOS levels.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.For more information on Reliability Metrics, please click here.
