CMOS Analog Switches
This family of CMOS analog switches offers low resistance
switching performance for analog voltages up to the supply
rails and for signal currents up to 80mA. “ON” resistance is
low and stays reasonably constant over the full range of
operating signal voltage and current. r_ON remains
exceptionally constant for input voltages between +5V and
-5V and currents up to 50mA. Switch impedance also
changes very little over temperature, particularly between
0^oC and 75^oC. r_ON is nominally 25Ω for HI-5049 and
HI-5051 and 50Ω for HI-5042 through HI-5047.
All devices provide break-before-make switching and are
TTL and CMOS compatible for maximum application
versatility. Performance is further enhanced by Dielectric
Isolation processing which insures latch-free operation with
very low input and output leakage currents (0.8nA at 25^oC).
This family of switches also features very low power
operation (1.5mW at 25^oC).
There are 7 devices in this switch series which are
differentiated by type of switch action and value of r_ON (see
Functional Description Table). The HI-504X and HI-505X series
switches can directly replace IH-5040 series devices, and are
functionally compatible with the DG180 and DG190 family
