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.
