Supply (Input): +2.7 to +18V supply.
Ground: Supply return.
Chip Select/Reset (Input): Active high at >2/3V_S. Output off
when low at<1/3V_S.
Output: CMOS totem-pole output.
Trigger (Input): Sets output high. Active low (at ≤ 2/3V_S
nominal).
Threshold (Dominant Input): Sets output low. Active high (at
≥ 2/3V_S nominal).
Trigger/Threshold (Input): Internally connected to both
threshold and trigger functions. See TRG and THR.
