NY9T001A-003a Function Overview:
    NY9T001A-003a Touch chip, providing NY9T001AS6-003a1(L/H Mode), SOT23-6(1*Touch 2*Out, NY9T001AS6-003a2(On/Off Mode, NY9T001AS8-003a (L/H or On/Off Mode by PE2 option) three options, NY9T001A-003a provides SOT23-6 and SOP8 two packages.

    1. When PE2 = x (suspended) and PA0 is in the touch state, all outputs are in the Busy state. When the touch leaves, the outputs return to the Initial state immediately, simulating the common Level/Hold (L/H) operation. (Tact Switch)
    2. When PE2 = 1 (VDD) and PA0 is touched once, all outputs are in the Busy state until the next touch, simulating the On/Off operation of the key switch. (Push Button / Slide Switch)
    PE0 Constant current output output High level, used to control the LED and high-trigger ics (for example: NY1, NY2, NY3 State-Machine IC).
    - PE1 Constant current output Low level, used to control LED and low-trigger ics (for example: NY4, NY5, NY7 4-bit MCU Speech IC).
    The NY9T001A-003a provides SOT23-6(NY9T001AS6-003a1 (L/H Mode)/NY9T001AS6-003a2 (On/Off Mode)), and SOP8 (NY9T001AS8-003a (L/H or) On/Off Mode by PE2 option)) Two types of encapsulation.

    Input: 1 touch key (PA0), 1 mode selection key (PE2).

    Output: Two output outlets (PE0, PE1).

    PA0: Touch Key. Select Level/Hold or On/Off based on the PE2 mode.
