The TS12A44513/TS12A44514/TS12A44515 construction is typical of most CMOS analog switches, except that
they have only two supply pins: V+ and GND. V+ and GND drive the internal CMOS switches and set their analog
voltage limits. Reverse ESD-protection diodes connected in series are internally connected between each
analog-signal pin and both V+ and GND. If an analog signal exceeds V+ or GND, one of the diodes will be
forward biased, but the other will be reverse biased preventing current flow.
Virtually all the analog leakage current comes from the ESD diodes to V+ or GND. Although the ESD diodes on a
given signal pin are identical and, therefore, fairly well balanced, they are reverse biased differently. Each is
biased by either V+ or GND and the analog signal. This means their leakages will vary as the signal varies. The
difference in the two diode leakages to the V+ and GND pins constitutes the analog-signal-path leakage current.
All analog leakage current flows between each pin and one of the supply terminals, not to the other switch
terminal. This is why both sides of a given switch can show leakage currents of the same or opposite polarity.
There is no connection between the analog-signal paths and V+ or GND.
V+ and GND also power the internal logic and logic-level translators. The logic-level translators convert the logic
levels to switched V+ and GND signals to drive the analog signal gates.
The logic-level thresholds are CMOS/TTL compatible when V+ is 5 V. As V+ is raised, the level threshold
increases slightly. When V+ reaches 12 V, the level threshold is about 3 V – above the TTL-specified high-level
minimum of 2.8 V, but still compatible with CMOS outputs.
CAUTION:
Do not connect the TS12A44513/TS12A44514/MAS4515 V+ to 3 V and then
connect the logic-level pins to logic-level signals that operate from 5-V supply.
Output levels can exceed 3 V and violate the absolute maximum ratings,
damaging the part and/or external circuits.
In 50-
Ω systems, signal response is reasonably flat up to 250 MHz (see Typical Operating Characteristics).
Above 20 MHz, the on response has several minor peaks that are highly layout dependent. The problem is not in
turning the switch on; it is turning it off. The OFF-state switch acts like a capacitor and passes higher frequencies
with less attenuation. At 10 MHz, OFF isolation is about –45 dB in 50-
Ω systems, decreasing (approximately 20
dB per decade) as frequency increases. Higher circuit impedances also make OFF isolation decrease. OFF
isolation is about 3 dB above that of a bare IC socket, and is due entirely to capacitive coupling.
