Product details
Overview
TLV9024RTER from Texas Instruments is a quad-channel, open-drain output precision comparator with 300 µV input offset voltage, 100 ns propagation delay, and rail-to-rail fault-tolerant inputs supporting ±0.2 V beyond supply rails. It operates from 1.65 V to 5.5 V and draws only 16 µA per channel, enabling low-power voltage monitoring in motor drive overcurrent detection circuits.
For engineers reviewing the TLV9024RTER datasheet, TLV9024RTER pinout, TLV9024RTER application, or TLV9024RTER equivalent, this page delivers verified functional specifications, package-validated pin functions, real-world use cases in industrial automation, and two confirmed alternative parts with documented technical and application differences.
Technical Context
The TLV9024RTER implements a high-speed, low-power comparator architecture optimized for precision threshold detection under noisy conditions. Its fault-tolerant input stage withstands up to 6 V independent of supply, preventing phase inversion and damage during transient overvoltage events.
As an open-drain device, it supports flexible level-shifting via external pull-up-compatible with logic voltages below or above V+-and integrates ESD protection rated at ±2 kV HBM. It is specified across –40°C to +125°C for industrial-grade reliability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Higher 2 mV offset, 300 ns delay, 100 µA/channel, no fault-tolerant inputs | Not suitable for >5 V input monitoring or low-power always-on designs | Select when cost sensitivity outweighs precision, speed, and input robustness requirements. |
| TLV9034RTER | Push-pull output (vs. open-drain), identical specs otherwise | Eliminates external pull-up but cannot support wired-OR bus topologies | Choose TLV9034RTER if driving LEDs or capacitive loads directly; retain TLV9024RTER for shared interrupt lines. |
Compared with LM339DR and TLV9034RTER, the TLV9024RTER uniquely combines ultra-low offset, nanosecond response, and fault-tolerant inputs in a quad open-drain configuration - making it optimal for space-constrained, high-reliability industrial monitoring where input overvoltage resilience and power efficiency are non-negotiable.

FAQ
What is the maximum input voltage the TLV9024RTER can tolerate without damage?
The TLV9024RTER supports input voltages from –0.3 V to 6 V relative to V–, independent of the supply voltage. This fault-tolerant capability allows safe operation during supply sequencing, bus transients, or sensor overvoltage events without external clamping components - a key differentiator versus standard comparators like LM339DR.
Does the TLV9024RTER require external pull-up resistors on its outputs?
Yes, the TLV9024RTER features open-drain outputs and requires external pull-up resistors to define the high-state logic level. Pull-up values between 2.2 kΩ and 10 kΩ are typical; selection depends on rise time requirements and load capacitance. The device itself does not include internal pull-ups.
Can the TLV9024RTER operate from a 1.8 V supply while maintaining full specification?
Yes, the TLV9024RTER is fully specified from 1.65 V to 5.5 V. At 1.8 V, it maintains 300 µV offset voltage, 100 ns propagation delay, and 16 µA per channel quiescent current across –40°C to +125°C - enabling direct interface with modern ultra-low-voltage microcontrollers and sensors.
How does the TLV9024RTER's input bias current affect high-impedance sensor interfaces?
With a typical input bias current of 5 pA, the TLV9024RTER introduces negligible error (<1 µV) when interfacing with sensor sources having impedances up to 100 MΩ. This enables accurate measurement from thermistors, RTDs, and high-value potentiometers without buffer amplifiers.
Is the TLV9024RTER pin-compatible with other devices in the TLV902x/TLV903x family?
No - the TLV9024RTER uses the RTE (16-pin WQFN) package with a unique 4×4 pin grid. Dual-channel variants (e.g., TLV9022) use 8-pin packages, and single-channel versions use 5-pin SC-70/SOT-23. Pin compatibility exists only within same-channel-count variants sharing identical package codes (e.g., TLV9024DR vs. TLV9024RTER differ only in package, not pinout).
