ST7SCR
PIN DESCRIPTION (Cont’d)
Legend / Abbreviations:
Type: I = input, O = output, S = supply
In/Output level: CT = CMOS 0.3VDD/0.7VDD with
input trigger
Output level: HS = 10mA high sink (on N-buffer
only)
Port and control configuration:
– Input:float = floating, wpu = weak pull-up, int = in-
terrupt, ana = analog
– Output: OD = open drain, PP = push-pull
Refer to “I/O PORTS” on page 30 for more details
on the software configuration of the I/O ports.
