DG308A/DG309 19-3926 Rev 0 3/91 Quad, SPST Analog Switches General Description Features The DG308A/DG309 are quad, single-pole-single-throw 60 r DS(ON) (SPST) analog switches. The DG308A is normally open Single/Bipolar-Supply Operation (SPST, NO), while the DG309 is normally closed (SPST, CMOS Logic Compatible NC). Both parts feature fast switching speeds and low on- resistance over the analog range. Other features include a Monolithic, Low-Power CMOS Design turn-on time under 120ns, a turn-off time under 90ns, and a channel on-resistance of 60. CMOS inputs provide Ordering Information reduced input loading and very low leakage currents. PART TEMP.

The DG308A/DG309 can be used with split sup- plies (5V to 20V) or a single positive supply (+5V to DG308ACK 0C to +70C 16 CERDIP +30V), while retaining CMOS-logic-compatible inputs.
