DESCRIPTION
The TLV349x family of push-pull output comparators fea-
tures a fast 6µs response time and < 1.2µA (max) nanopower
capability, allowing operation from 1.8V – 5.5V. Input com-
mon-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 SOT23-5 and SO-8. The dual (TLV3492) comes in
SOT23-8 and SO-8. The quad (TLV3494) is available in
TSSOP-14 and SO-14.
The TLV349x is excellent for power-sensitive, low-voltage
(2-cell) applications.
