ELECTRICAL CHARACTERISTICS—Single +5V Supply (continued)

(V+ = +4.2V to +5.5V, VIH = +2.0V, VIL = +0.8V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at V+ = +5.0V,

TA = +25°C, unless otherwise noted.) (Notes 3, 4)

Note 3:

UCSP parts are 100% tested at +25°C only, and guaranteed by design over the specified temperature range. µMAX parts

are 100% tested at TMAX and guaranteed by design over the specified temperature range.

Note 4:

The algebraic convention used in this data sheet is where the most negative value is a minimum and the most positive

value is a maximum.

Note 5:

Guaranteed by design for UCSP parts.

Note 6:

∆RON = RON(MAX) - RON(MIN).

Note 7:

Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the

specified analog signal ranges.

Note 8:

Guaranteed by design.

Note 9:

Off-Isolation = 20log10 (VCOM / VNO), VCOM = output, VNO = input to off switch.

Note 10: Between any two switches.
