Product details

Overview

UPC177GR(20)-9LG-E1-A from Renesas Electronics is a single-supply quad comparator IC with open-collector outputs, designed for extended-temperature industrial applications (−40 °C to +125 °C). It features ±1 mV typical input offset voltage, 1.6 µs typical pulse response time, and operates from +2 V to +32 V supply range - enabling precise voltage monitoring in battery-powered and 24 V industrial control systems.

For engineers reviewing the UPC177GR(20)-9LG-E1-A datasheet, UPC177GR(20)-9LG-E1-A pinout, UPC177GR(20)-9LG-E1-A application, or UPC177GR(20)-9LG-E1-A equivalent, key selection criteria include its extended temperature rating, low-voltage operation down to +2 V, open-collector output compatibility with wired-OR logic, and verified performance across −40 °C to +125 °C ambient without derating until 71 °C.

Technical Context

This quad comparator uses PNP-input transistor pairs to achieve rail-to-rail common-mode input range (0 V to V₊−1.5 V) and low input bias current (20 nA typ.). Its internal architecture supports single-supply operation while maintaining high DC gain (200,000 typ.) and fast transient response - critical for threshold detection and hysteresis-based window comparators.

The device implements four independent comparators in a single 14-pin TSSOP package, each with open-collector output capable of sinking up to 16 mA (typ.) at V_OL ≤ 0.4 V. Thermal design is supported by a junction-to-ambient thermal resistance of 144 °C/W and defined de-rating (−7.0 mW/°C above 71 °C), validated on standard glass-epoxy PCBs.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	+2 V to +32 V - enables direct use with 3.3 V, 5 V, 12 V, and 24 V rails without level-shifting.
Input Offset Voltage	±1 mV (typ.) - ensures accurate threshold detection within ±1 mV error at room temperature.
Pulse Response Time	1.6 µs (typ.) - supports reliable edge detection in signals up to ~300 kHz bandwidth.
Output Sink Current	16 mA (typ.) - drives standard LEDs, small relays, or logic inputs directly without external buffers.
Operating Temperature	−40 °C to +125 °C - qualified for under-hood automotive, motor drive, and industrial PLC environments.
Common-Mode Input Range	0 V to V₊−1.5 V - accepts inputs from ground up to 1.5 V below supply, simplifying sensor interface design.
Input Bias Current	20 nA (typ.) - minimizes loading on high-impedance sources like thermistors or photodiodes.

Pinout & Package

UPC177GR(20)-9LG-E1-A is housed in a 14-pin plastic TSSOP package (JEITA code P-TSSOP14-0225-0.65), measuring 5.15 mm × 4.40 mm × 1.20 mm max, with 0.65 mm lead pitch and embossed tape packaging (E1 orientation: pin 1 at draw-out side).

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 13, 14	Output (OUT1–OUT4)	Open-collector outputs - require external pull-up to define logic HIGH level and enable wired-OR bus configurations.
3, 5, 7, 9	Inverting Input (IN1–IN4)	Negative input terminals - accept analog voltages within VICM range (0 V to V₊−1.5 V).
4, 6, 8, 10	Non-inverting Input (II1–II4)	Positive input terminals - used for reference or signal comparison; input bias current flows out of these pins.
11	V₊	Positive power supply terminal - supports +2 V to +32 V single-supply operation.
12	V₋ / GND	Ground reference terminal - serves as common return and lower bound of input/output voltage ranges.

Key Features

Feature	Design Value
Rail-to-rail input capability	Common-mode range extends to V₋ (GND) and up to V₊−1.5 V - eliminates need for input biasing resistors in ground-referenced sensing.
Extended temperature grade	Rated for −40 °C to +125 °C operation - qualified for engine control units, power inverters, and outdoor industrial enclosures.
Low quiescent current	1.1 mA typical supply current - reduces system power budget in always-on monitoring circuits.
Wired-OR output topology	Four independent open-collector outputs - allows multiple comparators to share one pull-up resistor and logic line, reducing component count.
High DC gain	200,000 typical voltage gain - ensures clean digital transitions even with small input overdrive (≥5 mV).

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad comparator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LM339DR	General-purpose grade (−40 °C to +85 °C), higher input offset (±2 mV min), slower response (1.3 µs typ. but with larger variation).	Limited to commercial/industrial ambient environments; not rated for extended-temperature operation.	Select when cost sensitivity outweighs temperature range and offset precision requirements.
TLV331IPWR	Single-channel, rail-to-rail input/output, lower supply range (+1.8 V to +5.5 V), 350 nA input bias, 150 ns propagation delay.	Optimized for ultra-low-voltage, high-speed portable applications - not suitable for 24 V systems or multi-channel integration.	Choose for battery-powered designs requiring sub-2 V operation and nanosecond-level timing - not a drop-in replacement.

Compared with LM339DR and TLV331IPWR, UPC177GR(20)-9LG-E1-A uniquely combines extended temperature operation (−40 °C to +125 °C), single-supply compatibility up to +32 V, and quad-channel integration in a compact TSSOP - making it optimal for space-constrained, high-reliability industrial monitoring where ambient extremes and wide supply ranges coexist.

FAQ

What is the maximum supply voltage rating for UPC177GR(20)-9LG-E1-A?

The absolute maximum supply voltage (V₊ − V₋) for UPC177GR(20)-9LG-E1-A is +36 V. However, the recommended operating range is +2 V to +32 V. Exceeding +36 V risks permanent damage, and operation above +32 V voids guaranteed electrical performance per the datasheet specifications. Always observe the −0.3 V to +36 V limit on all pins relative to V₋.

Does UPC177GR(20)-9LG-E1-A support dual-supply operation?

Yes, UPC177GR(20)-9LG-E1-A supports dual-supply operation with ±1 V to ±16 V per rail (V_±). The datasheet specifies dual-supply conditions explicitly in the Recommended Operating Conditions table. When used in dual-supply mode, the common-mode input range remains referenced to V₋, and output behavior follows standard open-collector sinking relative to V₋.

What is the meaning of "E1" in UPC177GR(20)-9LG-E1-A?

The "E1" suffix in UPC177GR(20)-9LG-E1-A denotes embossed tape packaging with pin 1 located at the draw-out side of the reel. This orientation is standardized per JEDEC and ensures consistent automated placement during SMT assembly. The "(20)" indicates a 2000-piece tape-and-reel quantity, and "-A" designates the standard-grade version with extended temperature qualification.

Can unused comparator channels in UPC177GR(20)-9LG-E1-A be left floating?

No - unused comparator inputs must not be left floating. Per the datasheet's "Use with Precautions" section, unused inputs should be tied to a valid potential within the common-mode range (e.g., V₋ or V₊−1.5 V) to prevent erratic output switching and increased supply current. Outputs may be left open (as they are open-collector), but inputs require defined DC bias.

Is UPC177GR(20)-9LG-E1-A pin-compatible with UPC339GR-9LG-A?

Yes - UPC177GR(20)-9LG-E1-A and UPC339GR-9LG-A share identical pin configuration, package (14-pin TSSOP), and electrical interface. The primary difference is temperature grade: UPC177GR(20)-9LG-E1-A is qualified for −40 °C to +125 °C, while UPC339GR-9LG-A is rated for −40 °C to +85 °C. Both devices are functionally interchangeable in pin layout and connection.
