circuitry for each set of latches, and a bipolar saturated driver for each

latch, the UCN5881EP provides low-power interface with maximum

flexibility. The driver includes thermal shutdown circuitry to protect

against damage from high junction temperatures and clamp diodes

for inductive load transient suppression.

ible with standard CMOS, PMOS, and NMOS circuits. TTL or DTL

circuits may require the use of appropriate pull up resistors. When

reading back, each data input will sink 8 mA (if its corresponding latch

is low) or source 400 A (if its corresponding latch is high). The read

back feature is for error checking. It allows the system to verify that

data has been received and latched.

solenoids, and stepping motors. The very-low output saturation

voltage makes this device well-suited for driving LED arrays. The

output transistors are capable of sinking 50 mA and will maintain at

least 20 V in the OFF state. Outputs may be paralleled for higher

current capability.
