Note 2: 28 to 33 pin (TC94A04AFG): Input level changes TTL/CMOS level by the command (42h: VS). Output is
fixed to CMOS level.
In case of TC94A04AFDG, pin number are 39 to 41 pins and 43 to 46 pins.
Note 3: In case of TC94A04AFDG, these are NC pins as below. Normally open, otherwise it connects to V_DD or
GND. 6, 10, 12, 16, 19, 22, 29, 31, 34, 36, 42, 44, 47, 51, 56, 62 to 64, 73, 77 pins.
