DATASHEET
ISL43112, ISL43113
Low-Voltage, Dual Supply, SPST, High Performance Analog Switches
The Intersil
ISL43112
and
ISL43113
are precision, high
performance analog switches designed to operate from ±1.5V
to ±6V supplies. These devices are fully specified for 10%
tolerance ±5V and ±3.3V supplies and feature supply and
leakage currents much lower than those of other single SPST
switches. Turn-on and turn-off times are also improved.
Targeted applications include battery powered equipment that
benefit from the devices’ low power consumption (250µW),
sub-nanoamp leakage currents and fast switching speeds
(t
ON
= 40ns, t
OFF
= 25ns). The small SOT-23 packages and
timing that delivers break-before-make operation, make this
family ideal for custom multiplexer applications. Additionally,
excellent r
ON
flatness maintains signal fidelity over the whole
input range, while micro packaging alleviates board space
limitations. All these benefits combine to make Intersil’s
newest line of low-voltage switches ideal solutions for “Next
Generation” designs.
The ISL4311x are Single-Pole/Single-Throw (SPST) switches, with
the ISL43112 being Normally Open (NO) and the ISL43113 being
Normally Closed (NC).
Table 1
summarizes the performance of this family. For single
supply versions, see the
ISL43110, ISL43111
datasheet.
