4.5 Ohm Quad SPST Analog Switches in UCSP
General DescriptionThe MAX4737/MAX4738/MAX4739 low-voltage, low on-
resistance (RON), quad single-pole/single throw (SPST)
analog switches operate from a single +1.8V to +5.5V
supply. These devices are designed for USB 1.1 and
audio switching applications.
The MAX4737/MAX4738/MAX4739 feature 4.5Ω RON (max) with 1.2Ω flatness and 0.4Ω matching between
channels. These new switches feature guaranteed
operation from +1.8V to +5.5V and are fully specified at 3V and 5V. These switches offer break-before-make
switching (1ns) with tON <80ns and tOFF <40ns at +2.7V. The digital logic inputs are +1.8V logic compatible with a
+2.7V to +3.6V supply.
These switches are packaged in a chip-scale package (UCSP™), significantly reducing the required PC board
area. The chip occupies only a 2mm x 2mm area and has a 4 x 4 bump array with a bump pitch of 0.5mm. These switches are also available in a 14-pin TSSOP and a 16-pin thin QFN (4mm x 4mm) package.

Note 1: Signals on COM_, NO_, or NC_ exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to maxi-
mum current rating.
Absolute Maximum RatingsStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

Note 3: UCSP parts are 100% tested at +25°C only, and guaranteed by design over the specified temperature range. TSSOP and thin QFN 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 and thin QFN parts.
Note 6: ΔRON = 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.
