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, low-voltage (two-cell) applications.
