The SN75468 and SN75469 are high-voltage, high1? 500-mA Rated Collector Current (Single Output) current Darlington transistor arrays. Each consists of ? High-Voltage Output 100 V seven NPN Darlington pairs that feature high-voltage ? Output Clamp Diodes outputs with common-cathode clamp diodes for ? Inputs Compatible With Various Types of Logic switching inductive loads. The collector-current rating of each Darlington pair is 500 mA. The Darlington ? Relay Driver Applications pairs may be paralleled for higher current capability. ? Higher-Voltage Versions of ULN2003A and Applications include relay drivers, hammer drivers, ULN2004A, for Commercial Temperature range lamp drivers, display drivers (LED and gas discharge), line drivers, and logic buffers

? Characterized for Use to 300 mA ? No Output Latch-Up at 55 V (After Conducting 300 mA) ? High-Voltage Outputs (100 V Typ) ? Output Clamp Diodes for Transient Suppression (300 mA, 70 V) ? TTL- or MOS-Compatible Diode-Clamped Inputs ? pnp Transistor Inputs Reduce Input Current ? Standard Supply Voltage ? Suitable for Hammer-Driver Applications ? Plastic DIP (P) With Copper-Lead Frame Provides Cooler Operation and Improved Reliability

The SN75ALSI97 is a monolithic, quadruple line receiver with 3-state outputs designed using advanced, low-power, Schottky technology. This technology provides combined improvements in bar design, tooling production, and wafer fabrication. This, in turn, provides significantly lower power requirements and permits much higher data throughput than other designs. The device meets the specifications of ITU Recommendations V.10, V.11, X.26, and X.27. It features 3-state outputs that 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.
