AS339AM-E1 - BCD Semiconductor Manufacturing Limited

LOW POWER LOW OFFSET VOLTAGE QUAD COMPARATORS AS339/339A

Data Sheet

May 2009 Rev. 2. 0 BCD Semiconductor Manufacturing Limited

General Description

The AS339/339A consist of four independent preci-

sion voltage comparators with a typical offset voltage

of 2.0mV and high gain. They are specifically

designed to operate from a single power supply over

wide range of voltages. Operation from split power

supply is also possible and the low power supply cur-

rent drain is independent of the magnitude of the

power supply voltage.

The AS339/339A series are compatible with industry

standard 339. AS339A has more stringent input offset

voltage than AS339.

The AS339 is available in DIP-14, SOIC-14 and

TSSOP-14 packages, AS339A is available in SOIC-14

package.

Note 1: Stresses greater than thos e listed under "Absolute Maximum Ratings" may cause permanent damage to the

device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond

those indicated under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum

Ratings" for extended periods may affect device reliability.

Note 2: This input current will only exist when the voltage at any of the inp ut leads is driven negative. It is due to

the collector-base junction of the input PNP transistors becoming forward biased and thereby acting as input diode

clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action on the IC chip. This

transistor action can cause the output vo ltage s of the comp arato rs to go to the V+ v oltage level (or to g round for a

large overdrive) for the time duration that an input is driven negative. This is not destructive and normal output

states will re-establish when th e input volt age, which was neg ative, again returns to a value greater than -0.3 VDC

(at 25oC).

BCD Semiconductor's Pb-free products, as designated with "E1" suffix in the part number, ar e RoHS compliant. Products with

"G1" suffix are available in green packages.

Note 3: Limits over the full temperature are guaranteed by design, but not tested in production.

Note 4: The input common-mode voltage of either input signal voltage should not be allowed to go negatively by more than

0.3V (at 25oC). The upper end of the common-mode voltage range is VCC-1.5V (at 25oC), but either or both inputs can go to

+36V without damages, independent of the magnitude of the VCC.

Limits in standard typeface are for TA=25oC, bold typeface applies over TA=-40oC to 85oC (Note 3), VCC=5V, GND=0V,

unless otherwise specified.
