Dual micropower comparator for extended-temperature designs
The TLC3702MD: With a maximum quiescent current of just 90 µA per device, it suits battery-powered and power-sensitive circuits where every microamp counts. The output stage is CMOS push-pull, which eliminates the need for an external pull-up resistor and drives TTL loads directly.
What the key ratings mean for your BOM
Propagation delay is 4.5 µs maximum — fast enough for most industrial control loops and sensor threshold detection but not for high-frequency switching; expect it to handle signals up to about 110 kHz before the delay dominates the timing budget. Input bias current is 5 pA typical at 5 V, which means negligible loading on high-impedance sources like pH probes or photodiode amplifiers — the comparator won't drag down your signal. Common-mode rejection ratio (CMRR) is 84 dB typical, giving you about 16 µV of offset shift per volt of common-mode change — solid for precision threshold comparisons in noisy environments.
Sourcing and compliance
RoHS3 compliant (ROHS3 Compliant), which covers the ten restricted substances including the four phthalates — no exemption paperwork needed for EU or California market entry.
