PRELIMINARY DATASHEET
4.5 OHM LOW VOLTAGE, HIGH BANDWIDTH, DUAL SPDT ANALOG SWITCH
IDTUS4717
Description
The IDTUS4717 low on-resistance (R
ON
), low voltage, dual
single-pole/double-throw (SPDT) analog switch operates
from a single +1.65 V to +5.5 V supply. The IDTUS4717
features a 4.5Ω (max) R
ON
for its NC switch and a 4.5Ω
(max) R
ON
for its NO switch at a +3.0 V supply. It also
features break-before-make switching action (1ns) with
t
ON
<80ns and t
OFF
<40ns at +2.7 V. The digital logic inputs
are 1.8 V logic-compatible with a +2.7 V to +3.3 V supply.
Available in 3x3 DFN, or 10-bump CSP package.

Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the IDTUS4717. These ratings, which are
standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these
or any other conditions above those indicated in the operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical
parameters are guaranteed only over the recommended operating temperature range. All voltages referenced to
ground.

Notes:
1. The algebraic convention used in this data sheet is where the most negative value is a minimum and the most positive value
a maximum.
2. UCSP parts are 100% tested at +25°C only and guaranteed by design and correlation at the full hot-rated temperature.
3. Guaranteed by design.

5. Flatness is defined as the difference between the maximum and minimum value of on resistance as measured over the
specified analog signal ranges.
6. Off-isolation = 20log10 (V
