No. A-11,407Developed for use with low-voltage LED and incandescent dis-plays 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-Darlingtonoutputs of each driver can continuously and simultaneously sink load currents of 100 mA at ambient temperatures of up to +75°C.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 connec-tions on the other, for simplified printed wiring board layouts.These drivers are packaged in plastic DlPs (suffix A) or surface-mountable wide-body SOlCs (suffix LW), and are rated for operation over the temperature range of -20°C to +85°C. The A2595SLW is also available for operation to -40°C. To order, change the suffix from ‘SLW’ to ‘ELW’.FEATURESI Non-Inverting Function(Input Low = Output ON)I 200 mA Current RatingI 100 mA Continuous and Simultaneous(All outputs) to +85°C I Low Saturation Voltage I TTL, CMOS, NMOS Compatible I Efficient Input/Output Pin Format I DIP or SOIC PackagingUDN2595A25958-CHANNELSATURATED SINK DRIVER115 Northeast Cutoff, Box 15036Worcester, Massachusetts 01615-0036 (508) 853-500050751001251502.50.5A L L O W AB L E P AC K A G E P O W E RD I S S I P A T I O N I N W A T T SAMBIENT TEMPERATURE IN °C2.01.51.025Dwg.
