Active production — BOM-fit for new designs
The MAX961EUA+T: ROHS3 compliance is confirmed on the manufacturer record, so the part meets the latest EU restriction directive without requiring a separate waiver or exemption check.
7 ns propagation delay and 3.5 mV hysteresis — threshold detection with noise margin
The 7 ns max propagation delay places this comparator in the high-speed class for a general-purpose device — it resolves input transitions fast enough for overcurrent detection, zero-crossing circuits, and clock-recovery paths where the decision window is tens of nanoseconds wide. Built-in 3.5 mV hysteresis provides a clean switching threshold without external positive feedback resistors; the dead band prevents output chatter when the input signal sits near the reference voltage or carries ripple. Outputs are CMOS, complementary, and TTL-compatible — the same pin drives a 3.3 V FPGA input, a 5 V TTL gate, or a complementary pair for differential signalling without a level translator.
80 dB CMRR and 86 dB PSRR mean the threshold accuracy holds up when the input common-mode voltage shifts or the supply rail carries switching noise from a nearby DC-DC converter — the comparator does not false-trigger on supply transients.
8-uMAX/uSOP package — PCB layout and storage notes
CT is available for prototype or low-volume builds. Store the reels in a dry cabinet below 30°C / 60% RH; the MSOP moisture sensitivity level is typically MSL-1, but confirm the reel label for bake requirements before reflow.
