Overview
UPC177GR(21)-9LG-E1-A from Renesas Electronics is a single-supply quad voltage comparator 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, 20 nA typical input bias current, and operates from +2 V to +32 V supply. It is used in precision threshold detection circuits requiring rail-to-rail common-mode input range down to GND.
For engineers reviewing the UPC177GR(21)-9LG-E1-A datasheet, UPC177GR(21)-9LG-E1-A pinout, UPC177GR(21)-9LG-E1-A application, or UPC177GR(21)-9LG-E1-A equivalent, key selection criteria include extended temperature rating, low-input-offset stability over temperature, open-collector output compatibility with wired-OR logic, and TSSOP-14 package suitability for high-density PCB layouts.
Technical Context
The UPC177GR(21)-9LG-E1-A implements a PNP-input stage differential amplifier architecture enabling common-mode input down to V− (GND) and operation from low +2 V supplies. Its open-collector outputs support flexible pull-up configurations and direct interface with TTL/CMOS logic or external loads up to 16 mA sink current.
It delivers 200,000 typical large-signal voltage gain and maintains stable performance across −40 °C to +125 °C ambient, with thermal de-rating starting at 71 °C (−7.0 mW/°C). The device is not rated for automotive safety-critical use and excludes radiation-hardened or AEC-Q100 qualification.
Key Specifications

FAQ
What is the operating temperature range of the UPC177GR(21)-9LG-E1-A?
The UPC177GR(21)-9LG-E1-A is rated for an operating ambient temperature range of −40 °C to +125 °C, making it suitable for under-hood automotive auxiliary modules, factory-floor PLC I/O cards, and outdoor power conversion equipment. This extended grade distinguishes it from the general-purpose UPC339GR-9LG (−40 °C to +85 °C) in the same family.
Does the UPC177GR(21)-9LG-E1-A support dual-supply operation?
Yes, the UPC177GR(21)-9LG-E1-A supports dual-supply operation with ±1 V to ±16 V ratings, though its primary design focus is single-supply use from +2 V to +32 V. When operated with dual supplies, the common-mode input range remains referenced to V−, and output saturation behavior follows the same open-collector sink characteristics.
What is the maximum output sink current specification for the UPC177GR(21)-9LG-E1-A?
The UPC177GR(21)-9LG-E1-A provides a typical output sink current of 16 mA per channel at VO ≤ 1.5 V, with a minimum guaranteed value of 6 mA under the same test conditions. This allows direct driving of LEDs, small relays, or TTL logic inputs without additional buffering stages.
Can unused comparator sections in the UPC177GR(21)-9LG-E1-A be left floating?
No - unused comparator inputs must not be left floating. Renesas recommends connecting both IN+ and IN− of unused sections to a defined potential within the common-mode input range (e.g., V− or mid-supply via resistor divider) to prevent erratic output switching and excessive supply current. Leaving inputs unconnected may cause oscillation or increased ICC.
Is the UPC177GR(21)-9LG-E1-A pin-compatible with the UPC339GR-9LG?
Yes, the UPC177GR(21)-9LG-E1-A and UPC339GR-9LG share identical pinout, package (TSSOP-14), and electrical interface - differing only in temperature grade and minor parameter distributions (e.g., input offset and bias current limits). Both use the same marking-side pin 1 orientation and embossed tape handling (E1/E2).
