3 Description

The TLV349x family of push-pull output comparators

features a fast 6-μs response time and < 1.2-μA

(maximum) nanopower capability, allowing operation

from 1.8 V to 5.5 V. Input common-mode range

beyond supply rails make the TLV349x an ideal

choice for low-voltage applications.

Micro-sized packages provide options for portable

and space-restricted applications. The single

(TLV3491) is available in 5-pin SOT-23 and 8-pin

SOIC packages. The dual (TLV3492) comes in 8-pin

SOT-23 and SOIC packages. The quad (TLV3494) is

available in both 14-pin TSSOP and SOIC packages.

The TLV349x is excellent for power-sensitive, lowvoltage

(two-cell) applications.
