| 2595 UDN2595A 8-CHANNEL SATURATED SINK DRIVERS Developed for use with low-voltage LED and incandescent displays requiring low output saturation voltage, the UDN2595A and A2595SLW meet many interface needs, including those exceeding the capabilities of standard logic buffers. The eight non-Darlington outputs of each driver can continuously and simultaneously sink load currents of 100 mA at ambient temperatures of up to +75C. The eight-channel driver's active-low inputs can be driven directly from TTL, Schottky TTL, DTL, 5 to 16 V CMOS, and NMOS logic. All input connections are on one side of the package, output connections on the other, for simplified printed wiring board layouts. These drivers are packaged in plastic DlPs (suffix A) or surfacemountable wide-body SOlCs (suffix LW), and are rated for operation over the temperature range of -20C to +85C. These devices are also available as the UDQ2595A and A2595ELW for operation to -40C. Dwg.
