This variant is in production, however, it has been deemed Pre-End of Life. The product is approaching end of life. Within a minimum of 6 months, the device
will enter its final, Last Time Buy, order phase. Status change: January 31, 2011. Suggested replacement: A1190LLHLX-T.

Variant is in production but has been determined to be NOT FOR NEW DESIGN. This classification indicates that sale of the variant is currently restricted to
existing customer applications. The variant should not be purchased for new design applications because obsolescence in the near future is probable. Samples
are no longer available. Status change: January 31, 2011.

wire than the more traditional open-collector output switches.
Additionally, the system designer gains inherent diagnostics
because output current normally
fl
ows in either of two narrowly-
speci
fi
ed ranges. Any output current level outside of these two
ranges is a fault condition. The A1180-83 family of devices also
features on-chip transient protection, and a Zener clamp to protect
against overvoltage conditions on the supply line.

Both devices are offered in two package styles: LH, a SOT-23W

and UA, a three-lead ultramini Single Inline Package (SIP) for
through-hole mounting. Each package is available in a lead (Pb)
free version (suf

Factory-programmed versions are also available. Refer to: A1140,
A1141, A1142, A1143, A1145, and A1146.
