SN55ALS195 Datasheet | Texas Instruments

description The SN55ALS195 and SN75ALS195 are four differential line receivers with 3-state outputs designed using advanced low-power Schottky technology. This technology provides bined improvements in die design, tooling production, and wafer fabrication, which in turn, provide lower power consumption and permit much higher data throughput than other designs. The devices meet the specifications of ANSI Standards EIA/ TIA-422-B and EIA/TIA-423-A and ITU Remendations V.10 and V.11. The 3-state outputs permit direct connection to a bus-organized system with a fail-safe design that ensures the outputs will always be high if the inputs are open. 1Y 1, 2EN NC 2Y 2A 3 2 1 20 19 9 10 11 12 13 4A 4Y NC 3, 4EN 3Y 2B GND NC 3B 3A - No internal connection † For surface-mount package, see the SN75ALS199. The devices are optimized for balanced multipoint bus transmission at rates up to 20 megabits per second. The input features high input impedance, input hysteresis for increased noise immunity, and an input sensitivity of ± 200 m V over a mon-mode input voltage range of ± 7 V. The devices also feature an active-high enable function for each of two receiver pairs. The SN55ALS195 and SN75ALS195 are designed for optimum performance when used with the SN55ALS194 and SN75ALS194 quadruple differential line drivers. The SN55ALS195 is characterized for operation over the full military temperature range of - 55°C to 125°C. The SN75ALS195 is characterized for operation from 0°C to 70°C.
