Product details
Overview
UPC177G2(3)-E2-A from Renesas Electronics is a single-supply quad comparator IC with open-collector outputs, ±2 mV typical input offset voltage, 1.3 µs typical pulse response time, and operation from +2 V to +32 V supply. It serves as a voltage comparison engine in industrial control interfaces, battery monitoring circuits, and threshold-detection subsystems where rail-to-rail input range down to ground is required.
For engineers reviewing the UPC177G2(3)-E2-A datasheet, UPC177G2(3)-E2-A pinout, UPC177G2(3)-E2-A application, or UPC177G2(3)-E2-A equivalent, key selection criteria include guaranteed common-mode input range (0 V to V+ − 1.5 V), output sink current capability (6–16 mA), temperature-stable offset performance (±2 mV typ. at 25 °C), and compatibility with wired-OR logic configurations.
Technical Context
The UPC177G2(3)-E2-A implements four independent PNP-input comparators in a single monolithic IC, enabling simultaneous multi-threshold detection without cross-channel interference. Its input stage operates with bias current flowing out of both IN+ and IN− pins, requiring external pull-up resistors for open-collector outputs and careful handling of unused inputs to avoid leakage-induced errors.
Designed for single-supply use with V− tied to GND, it supports common-mode input voltages from ground up to V+ − 1.5 V and delivers fast switching (1.3 µs typ.) under 5.1 kΩ load with 5 mV overdrive. The device is not rated for dual-supply operation beyond ±16 V, and its absolute maximum differential input voltage is ±36 V.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Higher input offset (±2.5 mV max), slower response (1.3 µs typ. but wider distribution), same SOP-14 package | Wider industrial acceptance; less stringent offset drift over temperature | Preferred where cost sensitivity outweighs tight offset tolerance and extended temp range is not required |
| TL331IDBVR | Single-channel, SOT-23-5 package; lower supply current (60 µA vs. 0.8 mA), but no quad integration | Used in space-constrained designs needing only one comparator; requires four units for quad functionality | Select when board area is critical and channel count can be distributed across multiple packages |
Compared with LM339DR and TL331IDBVR, UPC177G2(3)-E2-A offers tighter offset stability (±2 mV typ.), guaranteed −40 °C to +85 °C operation, and integrated quad functionality in one SOP-14 package-making it optimal for compact, high-accuracy industrial monitoring systems.

FAQ
What is the operating supply voltage range for UPC177G2(3)-E2-A?
The UPC177G2(3)-E2-A operates from +2 V to +32 V on a single positive supply with V− tied to ground. It is not specified for dual-supply operation beyond ±16 V, and reverse supply connection may damage the IC. This range supports direct integration into 3.3 V, 5 V, 12 V, and 24 V systems without auxiliary regulators. The UPC177G2(3)-E2-A datasheet specifies absolute maximum supply voltage as −0.3 V to +36 V.
Does UPC177G2(3)-E2-A support rail-to-rail input operation?
No-UPC177G2(3)-E2-A supports common-mode input voltages from ground (V−) up to V+ − 1.5 V, not full rail-to-rail. Inputs below V− − 0.3 V risk parasitic diode conduction and potential damage. For ground-referenced sensing, this range is sufficient; however, signals near V+ require attenuation or level-shifting. The UPC177G2(3)-E2-A electrical characteristics table confirms VICM = 0 V to V+ − 1.5 V (typ.) at 25 °C.
What is the output configuration of UPC177G2(3)-E2-A and how should it be used?
UPC177G2(3)-E2-A features open-collector outputs on pins 1, 7, 8, and 14. Each output must be pulled up externally via a resistor to V+ or another logic rail. This configuration enables wired-OR logic, mixed-voltage interfacing, and direct driving of LEDs or optocouplers. The UPC177G2(3)-E2-A sink current capability is 6 mA minimum and 16 mA typical at VO ≤ 1.5 V, verified per datasheet test conditions.
Can unused comparators in UPC177G2(3)-E2-A be left floating?
No-unused comparators must not be left floating. The UPC177G2(3)-E2-A datasheet recommends connecting both inputs of unused sections to a fixed potential within the common-mode range (e.g., V+/2 via resistor divider) and tying the output to V+ through a pull-up. Floating inputs cause unpredictable output states and increased supply current. This guidance appears in the "USE WITH PRECAUTIONS" section of the UPC177G2(3)-E2-A datasheet (R03DS0139EJ0200).
What is the temperature range qualification for UPC177G2(3)-E2-A?
The UPC177G2(3)-E2-A is qualified for an operating ambient temperature range of −40 °C to +85 °C, designated for communication industry applications per the datasheet. This exceeds the −20 °C to +80 °C rating of the UPC339G2 variant. The specification is confirmed in the Absolute Maximum Ratings table on page 2 of the UPC177G2(3)-E2-A datasheet (R03DS0139EJ0200 Rev.2.00).
