A1201, A1202,
A1203, and A1204
Continuous-Time Bipolar Switch Family
provide magnetically optimized solutions for most applications.
Package LH is a SOT23W, a miniature low-profile surface-mount
package, while package UA is a three-lead ultramini SIP for through-
hole mounting. Each package is lead (Pb) free, with 100% matte
tin plated leadframes.

the family are identical, except for magnetic switchpoints.
The small geometries of the BiCMOS process allow these devices
to be provided in ultrasmall packages. The package styles available

The variants cited in this footnote are in production but have been determined to be NOT FOR NEW DESIGN. This classification indicates that
sale of this device is currently restricted to existing customer applications. The variants should not be purchased for new design applications
because obsolescence in the near future is probable. Samples are no longer available. Status change: October 31, 2006. These variants include:
A1204ELHLT-T, A1204EUA-T, A1204LLHLT-T, and A1204LUA-T.
