Detailed Description
The ISL54051 and ISL54052 are bidirectional, single
pole/single throw (SPST) analog switches. They offer
precise switching capability from a single 1.8V to 5.5V
supply with low on-resistance and high speed operation.
With a single supply of 5V the typical on-resistance is only
0.8
Ω
, with a typical turn-on and turn-off time of: t
ON
= 24ns,
t
OFF
= 10ns. The devices are especially well suited for
portable battery powered equipment due to their low
operating supply voltage (1.8V), low power consumption
(5.5
μ
W), low leakage currents (300nA max) and tiny
μ
TDFN
package.
The ISL54051 is a single normally open (NO) SPST analog
switch. The ISL54052 is a single normally closed (NC) SPST
analog switch.
Supply Sequencing and Overvoltage Protection
With any CMOS device, proper power supply sequencing is
required to protect the device from excessive input currents,
which might permanently damage the IC. All I/O pins contain
ESD protection diodes from the pin to V+ and to GND (see
Figure 6). To prevent forward biasing these diodes, V+ must
be applied before any input signals, and the input signal
voltages must remain between V+ and GND. If these
conditions cannot be guaranteed, then one of the following
two protection methods should be employed.
Logic inputs can easily be protected by adding a 1k
Ω
resistor in series with the input (see Figure 6). The resistor
limits the input current below the threshold that produces
permanent damage, and the sub-microamp input current
produces an insignificant voltage drop during normal
operation.
