UDN2595A (DIP)
8-CHANNEL SATURATED SINK DRIVER
Developed with low-voltage incandescent displays requiring output saturation voltage, UDN2595A A2595SLW meet many interface needs, including those exceeding capabilities standard logic buffers. eight non-Darlington outputs each driver continuously simultaneously sink load currents ambient temperatures +75°C. eight-channel driver's active-low inputs driven directly from TTL, Schottky TTL, DTL, CMOS, NMOS logic. input connections side package, output connections other, simplified printed wiring board layouts.
