Schmitt Input
TC94A48FG
Description
Schmitt Input.
5V tolerant.
B
A voltage can be applied to this pin even when the power
supply pin of the TC94A48FG is driven to 0V.
Push-pull output.
The amplitude is 3.3 V. If external devices require 5V
C
amplitude, perform a level conversion.
Open-drain output
This pin must be pulled up to VDD or 5V externally.
D
Schmitt input and open-drain output
This pin must be pulled up to VDD or 5V externally. A
voltage can be applied to this pin even when the power
supply pin of the TC94A48FG is driven to 0V.
E
[Caution] When using the pin for input, connect it to an
open-drain output pin of an external device.
