METAL WELDED PACKAGE

DD211

DD211B

DD211M*

A dual DD111 with current programming pins

omitted. This driver is often used in SPDT applications

by driving the inverting input of one channel and the

noninverting input of the other channel from the same

TTL input signal.

1. W hen using channel 1 inverting input pin 4, connect

bias pin 5 to non-inverting input pin 6.

2. W hen using channel 2 inverting input pin 11,.

connect bias pin 10 to non-inverting pin 9.

3. W hen using channel 1 non-inverting input pin 6,

connect bias pin 5 to inverting input pin 4.

4. W hen using channel 2 non-inverting input pin 9,

connect bias pin 10 to inverting input pin 11.

5. The two drivers are identical except for quiescent

positive output current, which is nominally 15 mA

for DD211 and 30 mA for DD211B.

6 W hen driving anode-grounded diodes, care must

be exercised to avoid excessive power dissipation.

V ee should be limited to -10 V, at which point the

negative output current will be approximately

-10 mA . Consult factory for design assistance.
