Active quad comparator in a compact 14-TSSOP
The STMicroelectronics TS864IPT is a general-purpose quad comparator packing four independent push-pull outputs into a 14-TSSOP package — 0.173" wide, 4.40 mm body, surface-mount footprint.
What the 2 µs propagation delay buys you
Maximum propagation delay is 2 µs — that sets the comparator's response ceiling. For a 100 kHz signal (10 µs period), the comparator settles in 20 % of the cycle, leaving enough margin for a downstream microcontroller to sample the output without missing edges.
Quiescent current maxes at 16 µA across all four comparators — that is 4 µA per channel, which matters for a sensor node that stays awake monitoring a threshold and cannot burn milliamps on the comparator stage. 70 dB CMRR typical keeps the threshold stable when the common-mode voltage shifts — on a battery-powered board where the ground reference drifts between charge cycles, that rejection prevents false triggers.
Temperature grade and package for field deployment
14-TSSOP with 0.65 mm pitch — a standard two-layer board can route the four comparator channels with a ground pour underneath. The 4.40 mm body width fits tight channel spacing on a multi-channel sensor card. RoHS3 compliant per — no lead, no conflict with EU or UKCA directives for equipment shipped into regulated markets.
