Quad, SPST Analog Switches
_______________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 60. 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.
