Features Up to 400 Mbps switching rates Flow-through pinout simplifies PCB layout 50 ps typical driver channel-to-channel skew 50 ps typical receiver channel-to-channel skew 3.3 V single power supply design TRI-STATE output control Internal fail-safe biasing of receiver inputs Low power dissipation (70 mW at 3.3 V static) High impedance on LVDS outputs on power down Conforms to TIA/EIA-644-A LVDS Standard Industrial operating temperature range (-40°C to +85°C) Available in low profile 16 pin TSSOP package Description The DS90LV049 is a dual CMOS flow-through differential line driver-receiver pair designed for applications requiring ultra low power dissipation, exceptional noise immunity, and high data throughput. The device is designed to support data rates in excess of 400 Mbps utilizing Low Voltage Differential Signaling (LVDS) technology. The DS90LV049 drivers accept LVTTL/LVCMOS signals and translate them to LVDS signals. On the other hand, the receivers accept LVDS signals and translate them to 3 V CMOS signals. The LVDS input buffers have internal failsafe biasing that places the outputs to a known H (high) state for floating receiver inputs. In addition, the DS90LV049 supports a TRI-STATE function for a low idle power state when the device is not in use. The EN and EN# inputs are ANDed together and control the TRI-STATE outputs. The enables are common to all four gates.

DS90LV049TMTX	CMOS7	0	21301	0	0	1584000	3	449464325

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.
