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. rON 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

0oC and 75oC. rON is nominally 25? for HI-5049 and

HI-5051 and 50? 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 25oC).

This family of switches also features very low power

operation (1.5mW at 25oC).

There are 7 devices in this switch series which are

differentiated by type of switch action and value of rON (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
