Pin Description (MIC1555 UTDFN)
Pin Number
Pin Name
Pin Function
1
VS
Supply (Input): +2.7 to +18V supply.
2
CS
Chip Select/Reset (Input): Active high at >2/3VS. Output off when low at <1/3VS. If chip select
functionality is not desired, CS may be connected directly to VS.
3, 4, 7, 9
NC
No Connect. This pin is not internally connected.
5
THR
Threshold (Dominant Input): Sets o
utput low. Active high (at ≥ 2/3VS nominal).
6
TRG
Trigger (Input): Sets output high.
Active low (at ≤2/3VS nominal).
8
GND
Ground: Supply return.
10
OUT
Output: CMOS totem-pole output.

T/T
Trigger/Threshold (Input): Internally connected to both threshold and trigger functions. When the
voltage at this pin is ≤2/3VS it will set the output high. When the voltage at this pin is ≥2/3VS it will set
the output low.
2
GND
Ground: Supply return.
3
CS
Chip Select/Reset (Input): Active high at >2/3VS. Output off when low at <1/3VS. If chip select
functionality is not desired, CS may be connected directly to VS.
4
VS
Supply (Input): +2.7 to +18V supply.
5
OUT
Output: CMOS totem-pole output.
