1. Working voltage 2.0V-5.5V
2. Working current @VDD=3V, typical value 2.0uA under no-load low power consumption mode, maximum value 4.0uA
3. The longest response time is about 220ms in low power mode @VDD=3V
4. The sensitivity can be adjusted by an external capacitor (1-50PF)
5. Stable human touch detection can replace traditional key switches
6. Provide low power consumption mode
7. Provide output mode selection (TOG pin) to choose direct output or latch (toggle) output
8. The longest output time is about 100 seconds (plus or minus 50%)
9. The Q pin is a CMOS output, which can be selected by (AHLB pin) as a high-level output or a low-level output.
10. The stabilization time is about 0.5 seconds after power-on. Do not touch the detection point during this period, and all functions are disabled at this time.
11. The automatic calibration function refreshes the reference value about every 1 second within 8 seconds after power-on. If there is a touch button within 8 seconds after power-on
Or if the button is not touched after 8 seconds, the recalibration cycle is switched to 4 seconds.
