DESCRIPTION

The TLV350x family of push-pull output comparators

feature a fast 4.5ns propagation delay and operation from

+2.7V to +5.5V. Beyond-the-rails input common-mode

range makes it an ideal choice for low-voltage applica-

tions. The rail-to-rail output directly drives either CMOS or

TTL logic.

Microsize packages provide options for portable and

space-restricted applications. The single (TLV3501) is

available in SOT23-6 and SO-8 packages. The dual

(TLV3502) comes in the SOT23-8 and SO-8 packages.

"#$%&' "#$%&( www.ti.com SBOS321D − MARCH 2005 − REVISED JULY 2005 APPLICATIONS INFORMATION The TLV3501 and TLV3502 both feature high-speed response and includes 6mV of internal hysteresis for improved noise immunity with an input common-mode range that extends 0.2V beyond the power-supply rails. SHUTDOWN A shutdown pin allows the device to go into idle when it is not in use. When the shutdown pin is high, the device draws about 2µA and the output goes to high impedance.

"#$%&' "#$%&( www.ti.com SBOS321D − MARCH 2005 − REVISED JULY 2005 RELAXATION OSCILLATOR The TLV350x can easily be configured as a simple and inexpensive relaxation oscillator. In Figure 4, the R2 network sets the trip threshold at 1/3 and 2/3 of the supply. Since this is a high-speed circuit, the resistor values are rather low in order to minimize the effect of parasitic capacitance. The positive input alternates between 1/3 of V+ and 2/3 of V+ depending on whether the output is low or high.

"#$%&' "#$%&( www.ti.com SBOS321D − MARCH 2005 − REVISED JULY 2005 PCB LAYOUT In a high-speed circuit, fast rising and falling switching transients create voltage differences across lines that would be at the same potential at DC. To reduce this effect, a ground plane is often used to reduce difference in voltage potential within the circuit board.
