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 +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 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 -20°C to +85°C. The A2595SLW is also
available for operation to -40°C. To order, change the suffix from
‘SLW’ to ‘ELW’.

NOTES: 1. Negative current is defined as coming out of the specified device pin.
2. The V

voltage limit guarantees a minimum output sink current per the specified conditions.
3. lS is measured with any one of eight drivers turned ON.
