SBOS262C – DECEMBER 2002 – REVISED MAY 2004
1.8V, Nanopower, PUSH-PULL OUTPUT COMPARATOR
FEATURES
q VERY LOW SUPPLY CURRENT: 0.8µA (typ) q INPUT COMMON-MODE RANGE 200mV BEYOND SUPPLY RAILS q SUPPLY VOLTAGE: +1.8V to +5.5V q HIGH SPEED: 6µs q PUSH-PULL CMOS OUTPUT STAGE q SMALL PACKAGES: SOT23-5 (Single) SOT23-8 (Dual)
DESCRIPTION
The TLV349x family of push-pull output comparators features a fast 6µs response time and < 1.2µA (max) nanopower capability, allowing operation from 1.8V – 5.5V. 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 spacerestricted 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.

Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied. (2) Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5V beyond the supply rails should be current limited to 10mA or less. (3) Short-circuit to ground, one amplifier per package.
ELECTROSTATIC DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
