V
translators, and set the input logic limits. The logic-level
translators convert the logic levels into switched V
and V
nals. This drive signal is the only connection between
the logic supplies and signals and the analog supplies.
V
The logic-level thresholds are TTL/CMOS compatible
when V
slightly, so when V
about 3.1V (above the TTL-guaranteed high-level mini-
mum of 2.8V, but still compatible with CMOS outputs).

These devices operate with bipolar supplies between
±2V and ±5V. The V

absolute maximum rating
These devices operate from a single supply between
+2V and +12V when V
the bipolar precautions must be observed. At room
temperature, they actually “work” with a single supply
near or below +1.7V, although as supply voltage
decreases, switch on-resistance and switching times
become very high.
