Product Overview
The TLV1805 is a Texas Instruments high voltage comparator for Signal_Chain designs requiring operation across a 3.3 V to 40 V recommended supply range. Its input stage supports rail-to-rail inputs with phase reversal protection, and the common-mode voltage range extends from (V-) - 0.2 V to (V+) + 0.2 V over -40 °C to +125 °C.
The output is a push-pull type with specified output swing within 300 mV of either rail at VS = 5 V and up to 5 mA source or sink current. Typical propagation delay is 250 ns for both high-to-low and low-to-high transitions with CL = 15 pF, and the device also includes power-on reset with a 45 µs typical power-up time requirement.
The TLV1805DBV pinout assigns OUT, V-, IN-, IN+, SHDN, and V+ across the 6-pin SOT-23 package. The active-high SHDN input places the output in a high-Z state, with 1.0 µs typical shutdown entry time and 2.3 µs typical shutdown exit time at CL = 15 pF.

Procurement Notes
When requesting a quote for TLV1805, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
FAQ
What supply range does the TLV1805 support?
The TLV1805 has a recommended operating supply voltage range of 3.3 V to 40 V, defined as VS=(V+)-(V-). Its absolute maximum supply voltage rating is -0.3 V to 42 V over the operating free-air temperature range.
What output type is used by the TLV1805?
