8-CHANNEL
SATURATED SINK DRIVER
Developed 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-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 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’.
