Product details
Overview
TLV2352MJG from Texas Instruments is a dual low-voltage differential comparator IC designed for single-supply operation across –55°C to 125°C, featuring 120µA typical supply current at 3V, 5pA typical input bias current, and open-drain N-channel outputs requiring external pullup. It supports 2V–8V supply range and is used in precision threshold detection within military-grade power monitoring and sensor interface circuits.
For engineers reviewing the TLV2352MJG datasheet, TLV2352MJG pinout, TLV2352MJG application, or TLV2352MJG equivalent, key selection criteria include extended temperature operation (–55°C to 125°C), ceramic DIP-8 packaging with SNPB lead finish, open-drain output architecture, low input bias current, and compatibility with TTL/MOS/CMOS logic families.
Technical Context
The TLV2352MJG implements two independent CMOS-based comparators with rail-to-rail common-mode input voltage range including ground, enabling direct sensing of signals referenced to system ground. Its high input impedance (>10¹²Ω) minimizes loading on high-impedance sources such as thermistors or photodiodes.
Each comparator features an N-channel open-drain output stage, supporting wired-AND logic configurations and flexible level translation via external pullup resistors. The device is fully characterized at both 3V and 5V under military-grade temperature extremes, with input offset voltage ≤5mV at 25°C and ≤10mV over full temperature range.

FAQ
What is the maximum operating temperature range for TLV2352MJG?
The TLV2352MJG is fully characterized from –55°C to 125°C, making it suitable for deployment in engine compartments, avionics bays, and downhole drilling equipment. This military-grade temperature range is validated per MIL-PRF-38535 requirements and confirmed in Section 5.8 and 5.10 of the official datasheet. All electrical specifications-including supply current, input offset voltage, and response time-are guaranteed across this full range. TLV2352MJG achieves this via process hardening and ceramic DIP packaging, distinguishing it from commercial variants like TLV2352IDR.
Does TLV2352MJG support single-supply operation with ground-referenced inputs?
Yes, TLV2352MJG supports true single-supply operation with common-mode input voltage range extending to ground (0V) at all supply voltages from 2V to 8V. This is explicitly specified in Section 5.2 (Recommended Operating Conditions) and Section 5.8 (Electrical Characteristics TLV2352M), where VICR min = 0V is guaranteed across temperature. The feature enables direct interfacing with shunt resistors, thermocouples, and other ground-referenced sensors without level-shifting circuitry-reducing component count and improving accuracy in TLV2352MJG-based designs.
What type of output stage does TLV2352MJG use, and how should it be interfaced?
TLV2352MJG uses N-channel open-drain output stages on both comparators, requiring external pullup resistors to establish logic-high voltage levels. As stated in Section 2 (Description), this architecture enables wired-AND logic, mixed-voltage interfacing, and flexible output voltage translation. For TTL compatibility, a 5kΩ pullup to 5V is typical; for 3.3V systems, 10kΩ is recommended. Output sinking current capability is 6–16mA (Section 5.8), and users must avoid shorting outputs directly to VDD to prevent thermal damage per Absolute Maximum Ratings.
Is TLV2352MJG RoHS compliant?
No, TLV2352MJG is not RoHS compliant due to its SNPB (tin-lead) lead finish and ceramic DIP (JG) package, as confirmed in the Packaging Information table (Page Addendum-1). It is designated "No" under RoHS in TI's official orderable part documentation. This makes TLV2352MJG suitable for military, aerospace, and legacy industrial applications where leaded finishes are required for solder joint reliability under thermal cycling and mechanical stress-per MIL-STD-883 and J-STD-001. RoHS-compliant alternatives like TLV2352IDR use NiPdAu or NIPDAU finishes but lack the same temperature rating and packaging.
How does the response time of TLV2352MJG compare between 3V and 5V operation?
At 5V supply, TLV2352MJG exhibits faster response: 900ns for TTL-level input steps (Section 5.10), versus 1400ns at 3V (Section 5.9), both measured with CL = 100pF. This 500ns difference reflects reduced internal drive strength at lower supply voltages. Designers selecting TLV2352MJG for time-critical supervision must verify timing margins at their actual operating voltage-especially in battery-powered systems where VDD may sag below 3.6V. The 100pF load condition reflects realistic PCB trace + probe capacitance, not ideal lab conditions.
