- Push-pull output stage directly drives CMOS logic levels without external pull-up resistors
- 5 mV maximum input offset voltage ensuring reliable threshold detection in precision window comparators
- Ceramic 8-pin DIP package with military-grade temperature stability for rugged and high-reliability applications
Applications
The TLC3702MJG is suited for battery-operated threshold detectors, window comparators, and analog-to-digital conversion front-ends in portable instruments where minimizing supply current is critical. Its low 30 nA input bias current allows direct comparison of signals from high-impedance sources such as photodiodes, thermistors, and piezoelectric sensors without loading errors. The ceramic DIP package makes it appropriate for industrial and military electronics requiring high reliability across extended temperature ranges.

Frequently Asked Questions
How does the TLC3702MJG's 30 nA input bias current benefit high-impedance sensor threshold detection?
With only 30 nA typical input bias current, the TLC3702MJG causes a voltage error of merely 3 mV across a 100 kΩ source impedance. This is well within the 5 mV offset voltage budget for a precision 2-channel window comparator, enabling direct comparison of signals from high-impedance resistive dividers, thermistors, and photodiode transimpedance amplifier outputs without adding buffer stages.
When is the TLC3702MJG's push-pull output preferred over an open-drain comparator output in logic interface designs?
Push-pull outputs actively drive both logic high and logic low, eliminating the external pull-up resistor required by open-drain comparators. This reduces component count and speeds up falling-edge transitions from microseconds to nanoseconds in capacitively-loaded CMOS logic lines, particularly valuable in clocked threshold detection circuits operating at signal rates above 100 kHz where pull-up RC time constants would limit response.
For a military or industrial ceramic package requirement, how does the TLC3702MJG's 8-pin CDIP differ from its plastic DIP alternatives?
The ceramic DIP package of the TLC3702MJG provides hermetic sealing that resists moisture ingress, making it suitable for MIL-STD-883 screened applications and long-duration storage in harsh environments. Plastic DIP comparators absorb moisture over time, leading to threshold drift and leakage current increases above 1 µA at elevated temperatures, whereas ceramic-packaged devices maintain 30 nA bias current specification across the full military temperature range.
