General Description
The MAX4737/MAX4738/MAX4739 low-voltage, low on-
resistance (R
ON
), 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 4.5
R
ON
(max) with 1.2
flatness and 0.4
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 t
ON
<80ns and t
OFF
<40ns at
+2.7V. The digital logic inputs are +1.8V logic compati-
ble 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
2mm area and
has a 4
4 bump array with a bump pitch of 0.5mm.
These switches are also available in a 14-pin TSSOP
package.
