DG308A
Data Sheet November 1999
Quad Monolithic SPST, CMOS Analog
Switch
The DG308A quad monolithic SPST, CMOS switch is latch
proof and is designed to block signals up to 30V
P-P
when
OFF. Featuring low ON resistance, low power consumption,
and rail-to-rail analog signal range, this switch is ideally
suited for high speed switching applications in
communications, instrumentation and process control. The
DG308A has single and dual supply capability. The input
thresholds are CMOS compatible.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. Signals on SX, DX, or INX exceeding V+ or V- will be clamped by internal diodes. Limit forward diode current to maximum current ratings.
2. θJA is measured with the component mounted on an evaluation PC board in free air.
