TLV3501 High-Speed Comparator

@@ -0,0 +1,52 @@+# 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. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Single high-speed comparator |+| Propagation delay | 4.5 ns typ |+| Output | Push-pull (rail-to-rail), no pull-up needed |+| Inputs | Rail-to-rail |+| Supply voltage | 2.7 V to 5.5 V |+| Shutdown | Yes (SHDN pin) |+| Operating temperature | -40 C to 125 C |++## Ordering variants++- `TLV3501DBV`+- `TLV3501DBVR`+- `TLV3501DBVT`+- `TLV3501D`+- `TLV3501DR`++## CAD (KiCad official)++- Symbol: `tlv3501.kicad_sym`+- Footprint: `tlv3501.kicad_mod`+- 3D model: SOT-23-6 body from KiCad `Package_TO_SOT_SMD/SOT-23-6`.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tlv3501.pdf) (33 pp, sha256 `fcfbeffce8746298`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
