Product details
Overview
LT1716CS5#TRMPBF from Analog Devices is a micropower, precision rail-to-rail comparator in a 5-lead TSOT-23 package, operating from 2.7V to 44V with 35µA quiescent current, ±1.5mV max input offset voltage, and Over-the-Top® input stage enabling common-mode operation up to 44V above V–-ideal for high-side lamp monitoring and power supply supervision in industrial and automotive systems.
For engineers reviewing the LT1716CS5#TRMPBF datasheet, LT1716CS5#TRMPBF pinout, LT1716CS5#TRMPBF application, or LT1716CS5#TRMPBF equivalent, this page delivers verified specifications, validated pin functions, real-world use cases in overvoltage-tolerant sensing, and confirmed alternative comparators for design flexibility under wide-supply and fault-tolerant conditions.
Technical Context
The LT1716CS5#TRMPBF employs a three-stage input architecture (NPN/PNP/common-base) enabling seamless operation across three distinct input voltage regions: below V–, within rails, and >44V above V–-with no phase reversal even when one input is forced 5V below V–. Its internal pull-up current source eliminates external resistive pull-ups while maintaining rail-to-rail output swing (within 35mV of V– and 55mV of V+).
It supports single- and split-supply configurations (±15V), features built-in 5kΩ input protection resistors limiting fault current to ≤1mA at –5V below V–, and delivers 5.5µs typical propagation delay into 10kΩ load with 100mV overdrive-optimized for fast, low-power threshold detection in harsh voltage environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 44V total-supports direct connection to 24V/36V industrial buses and automotive battery rails without level-shifting. |
| Input Common-Mode Range | Extends 44V above V–, independent of V+-enables high-side sensing of loads referenced to ground or negative rails. |
| Quiescent Current | 35µA max at 25°C-enables always-on monitoring in battery-powered or energy-constrained systems. |
| Input Offset Voltage | 1.5mV max over –40°C to 85°C-ensures accurate threshold detection across temperature without calibration. |
| Output Swing | Within 35mV of V– and 55mV of V+-provides reliable logic-level compatibility with 3.3V/5V microcontrollers in single-supply designs. |
| Propagation Delay | 5.5µs typical (100mV overdrive, 10kΩ load)-balances speed and power for medium-frequency event detection (e.g., overcurrent flagging). |
| Operating Temperature | –40°C to +85°C-qualified for extended industrial and commercial environments per LT1716C grade. |
Pinout & Package
LT1716CS5#TRMPBF is housed in a low-profile (1mm height) 5-lead TSOT-23 (S5) plastic package, JEDEC MO-193 compliant, with exposed pad not connected internally-designed for space-constrained PCB layouts and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Open-drain–like output stage | Class-B pull-up current source drives loads up to 44V above V–; sinks ≥10mA; swings rail-to-rail without external pull-up. |
| 2 (V–) | Negative supply reference | Ground or negative rail connection; inputs tolerate –5V relative to this pin; internal protection limits fault current to ≤1mA. |
| 3 (+IN) | Noninverting input | Accepts voltages from –5V to 44V above V–; bias current varies by region (–4nA PNP / +10nA NPN / VIN/5kΩ below V–). |
| 4 (–IN) | Inverting input | Identical voltage range and bias behavior as +IN; differential input tolerance up to 44V ensures robustness against transients. |
| 5 (V+) | Positive supply | Supplies internal circuitry; removal shuts down device (IB < 3nA); reverse-battery protected up to 20V. |
Key Features
| Feature | Design Value |
|---|---|
| Over-the-Top® Input Stage | Enables direct high-side sensing-e.g., monitoring 44V lamp voltage with V+ = 5V-eliminating level-shifters and reducing BOM count. |
| Internal Pull-Up Current Source | Replaces external pull-up resistor, saving board space and reducing standby power-critical for always-on fault monitors. |
| Rail-to-Rail Output Swing | Delivers full logic swing (e.g., 0.035V–4.945V on 5V supply) compatible with CMOS/TTL inputs without interface circuitry. |
| Input Fault Tolerance Below V– | Valid output maintained with either input at –5V relative to V–, supported by internal 5kΩ resistors limiting current to 1mA. |
| AEC-Q100 Qualified Variant Available | LT1716HS5#WTRPBF meets automotive reliability requirements-LT1716CS5#TRMPBF shares identical electrical specs and pinout for drop-in qualification path. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT1719CS5#TRMPBF | Faster propagation delay (4.5ns vs 5.5µs), higher supply current (1.2mA), no Over-the-Top® input-requires level-shifting for >V+ inputs. | Better suited for high-speed digital edge detection; unsuitable for direct high-side sensing above V+. | Select LT1719CS5#TRMPBF only when speed >1MHz is required and input voltage stays within rails. |
| LMV7215M5X/NOPB | Lower supply current (650nA), lower VCC range (2.7V–5.5V), no Over-the-Top®-max input = V+ + 0.3V. | Ideal for ultra-low-power battery sensors but cannot replace LT1716CS5#TRMPBF in 24V+ or fault-tolerant designs. | Choose LMV7215M5X/NOPB for sub-1µA portable devices where input voltage never exceeds V+. |
Compared with LT1716CS5#TRMPBF, LT1719CS5#TRMPBF trades micropower and Over-the-Top® capability for nanosecond speed, while LMV7215M5X/NOPB sacrifices voltage range and fault tolerance for nanoamp quiescent current-making LT1716CS5#TRMPBF uniquely balanced for industrial 24V–44V monitoring with low power and robustness.

The LT1716CS5#TRMPBF supports an input common-mode voltage up to 44V above V–, independent of V+, and tolerates differential input voltages up to 44V. It also accepts inputs as low as 5V below V– with valid output-enabled by internal 5kΩ protection resistors that limit fault current to ≤1mA. This specification is confirmed in the Absolute Maximum Ratings and Applications Information sections of the official datasheet.
Does the LT1716CS5#TRMPBF require an external pull-up resistor on its output?
No, the LT1716CS5#TRMPBF integrates a class-B pull-up current source that eliminates the need for an external pull-up resistor. Its output can drive loads connected to a supply up to 44V above V–, delivering rail-to-rail swing (within 35mV of V– and 55mV of V+) while saving board space and reducing power consumption-verified in the Features and Electrical Characteristics tables of the datasheet.
What is the guaranteed operating temperature range for the LT1716CS5#TRMPBF?
The LT1716CS5#TRMPBF is rated for operation from –40°C to +85°C, corresponding to the LT1716C grade. This range is explicitly specified in the Order Information table and Electrical Characteristics notes, and all key parameters-including input offset voltage (1.5mV max), supply current (35µA typ), and propagation delay-are guaranteed across this full industrial temperature span.
Can the LT1716CS5#TRMPBF be used in automotive applications?
The LT1716CS5#TRMPBF itself is not AEC-Q100 qualified; however, the pin-compatible LT1716HS5#WTRPBF variant is automotive-qualified for –40°C to +125°C operation. Both share identical electrical specifications, S5 package, and pinout-allowing direct migration to automotive designs with full reliability documentation available from Analog Devices upon request.
