Notes:

5. CX1 must be placed within 0.7 cm of the HSDL-3601 to obtain optimum noise immunity.

6. In environments with noisy power supplies, supply rejection performance can be enhanced by

including CX2, as shown in “HSDL-3601 Functional Block Diagram” in page 3.

CAUTIONS:

The BiCMOS inherent to the design of this component increases the component’s

susceptibility to damage from electrostatic discharge (ESD). It is advised that normal static precautions

be taken in handling and assembly of this component to prevent damage and/or degradation which may

be induced by ESD.

Marking Information

The HSDL-3601#007/017 is marked

“3601YYWW’ on the shield where “YY”

indicates the unit’s manufacturing year,

and “WW” refers to the work week in

which the unit is tested.

The HSDL-3601#008/018 is marked a

“black” dot on the shield.
