Product details
Overview
TLV2354MJB from Texas Instruments is a quadruple low-voltage differential comparator IC designed for single-supply operation down to 2 V, featuring 240 µA typical supply current at 3 V, 5 mV max input offset voltage at 25°C, and operation across –55°C to 125°C. It delivers high input impedance (10¹² Ω typ), 5 pA typical input bias current, and open-drain N-channel outputs compatible with TTL/MOS/CMOS logic-used in precision threshold detection within military-grade power management systems.
For engineers reviewing the TLV2354MJB datasheet, TLV2354MJB pinout, TLV2354MJB application, or TLV2354MJB equivalent, key selection considerations include its MIL-PRF-38535 qualified ceramic DIP package, extended temperature range, ESD-hardened LinCMOS™ architecture, and open-drain output configuration requiring external pull-up resistors for wired-AND functionality.
Technical Context
The TLV2354MJB implements four independent comparators using Texas Instruments' LinCMOS™ process, enabling ultra-low input bias current and rail-to-rail common-mode input range including ground. Its open-drain outputs support flexible logic interfacing and positive-logic wired-AND configurations without internal level-shifting circuitry.
Characterized per MIL-PRF-38535 requirements, the device guarantees tested performance across –55°C to 125°C, with fully specified parameters including input offset voltage (≤5 mV at 25°C), supply current (≤800 µA over full temp range), and low-level output voltage (≤700 mV at IOL = 2 mA).

Equivalent & Alternatives
The following parts are listed as comparable options for similar quadruple low-voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2354MWB | Ceramic flatpack (CFP-14) package; identical electrical specs and temp range; different mechanical footprint and lead form. | Preferred where lower profile or improved thermal dissipation is required; incompatible with DIP socket layouts. | Select TLV2354MWB when board space constraints favor flatpack mounting or when higher thermal conductivity is needed. |
| 5962-9688201Q2A | LCCC-20 package; same MIL-PRF-38535 qualification and –55°C to 125°C range; includes two unused pins and different pinout. | Used in high-reliability hybrid modules where surface-mount LCCC is standard; requires PCB redesign. | Choose 5962-9688201Q2A for hybrid microcircuit assemblies or when LCCC's superior high-frequency stability is critical. |
Compared with TLV2354MJB, TLV2354MWB offers identical performance in a lower-profile CFP package suited for compact avionics enclosures, while 5962-9688201Q2A provides enhanced RF immunity and thermal cycling resilience in LCCC format-neither is pin-compatible, requiring layout adaptation for either alternative.

FAQ
What is the operating temperature range of the TLV2354MJB?
The TLV2354MJB is fully characterized and qualified for operation from –55°C to 125°C, meeting MIL-PRF-38535 requirements for defense and aerospace applications. This extended range is validated across all key parameters including input offset voltage, supply current, and propagation delay-ensuring reliable performance in engine bays, space payloads, and artillery systems.
Does the TLV2354MJB have internal pull-up resistors on its outputs?
No, the TLV2354MJB features N-channel open-drain outputs that require external pull-up resistors to establish a logic-high voltage level. This design enables flexible voltage translation (e.g., pulling up to 3.3 V while powered from 5 V) and wired-AND bus configurations-critical for fault-bus architectures in safety-critical systems.
Is the TLV2354MJB RoHS compliant?
The TLV2354MJB uses SnPb (tin-lead) lead finish and is not RoHS compliant, consistent with its MIL-PRF-38535 qualification for high-reliability military applications. Its exemption from RoHS Directive 2011/65/EU Annex III applies due to reliability requirements in defense electronics where Pb-free alternatives exhibit higher solder joint fatigue risk.
How does the input common-mode range of TLV2354MJB support ground-referenced sensing?
The TLV2354MJB's common-mode input voltage range includes ground (0 V) across its full supply range (2 V to 8 V), allowing direct connection of inverting or non-inverting inputs to ground-referenced signals-such as thermistor dividers or op-amp outputs-without level-shifting circuitry, simplifying analog front-end design in battery-powered munitions.
What is the maximum capacitive load the TLV2354MJB can drive reliably?
The TLV2354MJB is characterized with CL = 100 pF in switching tests at 25°C, showing 1300 ns typical response time at 5 V supply. While not rated for continuous capacitive loading, it reliably drives PCB traces and scope probes up to 100 pF; larger loads require buffering or reduced slew-rate design to maintain timing accuracy in precision timing circuits.
