Texas Instruments TLC3704MJB

Overview

TLC3704MJB from Texas Instruments is a quad micropower LinCMOS voltage comparator designed for single-supply operation across −55°C to 125°C, delivering 200 µW typical supply power at 5 V, 2.7 µs typical propagation delay (tPLH) with 5-mV overdrive, and ±8 mA push-pull CMOS output drive-enabling direct capacitive load interfacing without external pullup resistors in military-grade sensor signal conditioning and power monitoring circuits.

For engineers reviewing the TLC3704MJB datasheet, TLC3704MJB pinout, TLC3704MJB application, or TLC3704MJB equivalent, key selection considerations include its extended temperature range (−55°C to 125°C), input offset voltage ≤10 mV over full temp range, 4 V to 16 V supply compatibility, and J-package ceramic DIP mechanical robustness for high-reliability analog threshold detection.

Technical Context

The TLC3704MJB integrates four independent comparators on a LinCMOS process, combining high input impedance (>10¹² Ω), ultra-low input bias current (5 pA typ at 25°C), and stable input offset voltage (≤10 mV over −55°C to 125°C). Its push-pull CMOS output stage eliminates need for external pullup resistors while maintaining TTL-compatible logic levels and driving ≥50 pF loads.

Designed for single-supply systems, it supports common-mode input voltage from 0 V to (VDD − 1.5 V) across full temperature range and features on-chip ESD protection rated to 2 kV HBM and 200 V CDM-critical for ruggedized avionics and defense electronics where transient immunity and long-term parameter stability are mandatory.

FAQ

What is the maximum operating temperature range for the TLC3704MJB?

The TLC3704MJB is characterized for continuous operation from −55°C to 125°C, meeting MIL-PRF-38535 requirements for full military temperature range. This specification is verified across all electrical parameters including input offset voltage (≤10 mV), supply current (≤175 µA), and propagation delay (≤4.5 µs at 125°C), making it suitable for downhole, avionics, and propulsion control environments.

Does the TLC3704MJB require an external pullup resistor on its outputs?

No, the TLC3704MJB features a push-pull CMOS output stage that actively drives both high and low states, eliminating the need for external pullup resistors. This design reduces power dissipation, saves PCB space, and simplifies interface to TTL or CMOS logic - confirmed by its ±8 mA output drive capability and 2.7 µs typical tPLH with 50 pF load at 5 V supply.

What is the input offset voltage specification for TLC3704MJB over temperature?

The TLC3704MJB has a maximum input offset voltage of 10 mV across its full operating temperature range of −55°C to 125°C, as specified in the "electrical characteristics" table for the TLC3704M variant. At 25°C, typical offset is 1.2 mV, and the distribution is tightly bounded (±5 mV for 698 units tested), ensuring predictable threshold accuracy in precision analog monitoring circuits.

Which package type does the TLC3704MJB use, and what are its mechanical advantages?

The TLC3704MJB uses a 14-pin ceramic dual-in-line package (J package), hermetically sealed with glass-to-metal leads. This construction provides superior moisture resistance, thermal cycling endurance, and long-term parameter stability compared to plastic packages - essential for aerospace, defense, and industrial applications exposed to humidity, vibration, and extreme thermal gradients.

How does the LinCMOS process benefit the TLC3704MJB's performance in sensor interface applications?

The LinCMOS process enables the TLC3704MJB to achieve ultra-low input bias current (5 pA typ at 25°C, ≤30 nA at 125°C) and high input impedance (>10¹² Ω), preserving signal integrity when interfacing with high-impedance sensors like thermistors, RTDs, or piezoelectric elements. It also delivers stable input offset voltage and excellent CMRR (≥82 dB) over temperature - critical for rejecting common-mode noise in noisy embedded systems.
