Maxim Integrated 

50Ω Low-Voltage, Quad SPST/Dual SPDT Analog

Switches in UCSP

ELECTRICAL CHARACTERISTICS—Single +5V Supply (continued)

(V+ = +5V ±10%, VIH = +2.0V, VIL = +0.8V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at V+ = +5V, TA = +25°C.)

Note 3: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used

in this data sheet.

Note 4: UCSP parts are 100% tested at +25°C only, and are guaranteed by design over temperature. TSSOP and Thin QFN parts

are 100% tested at +85°C and guaranteed by design over temperature.

Note 5: ∆RON = RON(MAX) - RON(MIN).

Note 6: UCSP and Thin QFN on-resistance matching between channels is guaranteed by design.

Note 7: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the

specified analog signal range.

Note 8: Guaranteed by design.

Note 9: Off-isolation = 20 log10 (VNO_/VCOM_), VNO_ = output, VCOM_ = input to off switch.

Note 10: Between any two switches.

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