_______________General Description

The DG308A/DG309 are quad, single-pole-single-throw

(SPST) analog switches. The DG308A is normally open

(SPST, NO), while the DG309 is normally closed (SPST,

NC). Both parts feature fast switching speeds and low on-

resistance over the analog range. Other features include a

turn-on time under 120ns, a turn-off time under 90ns, and a

channel on-resistance of 60Ω. CMOS inputs provide

reduced input loading and very low leakage currents.

Both parts feature a 44V maximum breakdown voltage rat-

ing that allows 30V peak-to-peak switch-off blocking

capacity. The DG308A/DG309 can be used with split sup-

plies (±5V to ±20V) or a single positive supply (+5V to

+30V), while retaining CMOS-logic-compatible inputs.
