What this triple Schmitt inverter does on the board
Each of the three independent inverters cleans up slow edges, suppresses noise on long traces, and provides hysteresis at the switching point. The 8-XSON (2x3 mm) package fits tight layouts where board area is at a premium.
Schmitt-trigger inputs — why they matter for signal integrity
The Schmitt-trigger action on each input gives clean transitions even with slowly ramping or noisy signals. Input low thresholds sit between 0.5V and 0.6V; input high thresholds between 1.9V and 2.1V, matching TTL logic levels at 5V. This hysteresis rejects chatter from mechanical switches, oscillator circuits, or long PCB traces that pick up coupled noise.
Temperature range and operating environment
Output drive is 4 mA source and sink, adequate for driving CMOS inputs or small LEDs through a resistor.
Propagation delay and capacitive load
Maximum propagation delay is 32 ns at 4.5V with a 50 pF load, which keeps timing margins healthy in most 5V logic chains below 10 MHz. The 8-XSON package (2x3 mm) has a low parasitic inductance, helping maintain signal edges at the output.
