TLV3501

Texas Instruments · Comparator · SOT-23-6

The TLV3501 is a high-speed comparator with 4.5 ns propagation delay, rail-to-rail inputs, and a push-pull output that needs no pull-up. A shutdown pin drops it to low power. It suits zero-crossing detection, pulse and clock recovery, and fast level triggering.

Pinout

Pin Name Type Function
1 -IN input Inverting (negative) analog input of the comparator. Input common-mode range extends 0.2 V beyond both supply rails; input bias current is typically 2 pA. Signals swinging more than 0.3 V beyond the rails must be current-limited to <= 10 mA.
2 V- power_in Negative (lowest) power supply. Typically tied to GND for single-supply operation; supports a total supply span of 2.7 V to 5.5 V between V+ and V- (2.2 V to 5.5 V operating range).
3 +IN input Noninverting (positive) analog input of the comparator. Input common-mode range extends 0.2 V beyond both supply rails; input bias current is typically 2 pA. Signals swinging more than 0.3 V beyond the rails must be current-limited to <= 10 mA.
4 V+ power_in Positive (highest) power supply. Supply voltage range is 2.7 V to 5.5 V nominal (2.2 V to 5.5 V operating). Bypass locally to V- with a low-ESR ceramic capacitor because of the 4.5 ns push-pull switching edges.
5 OUT output Push-pull CMOS comparator output. Rail-to-rail swing (VOH/VOL within 30 mV typical of the rails at +/-1 mA). Directly drives CMOS or TTL logic. Short-circuit current to GND is limited to 74 mA (max).
6 SHDN input Active-low shutdown / enable input. When SHDN is within 0.9 V of V+ the comparator is enabled; when SHDN is more than 1.7 V below V+ the comparator is disabled and idles at ~2 uA. Turn-on ~100 ns, turn-off ~30 ns. Do not leave floating.
