TERMINAL FUNCTIONS (UCC27523/UCC27524/UCC27525)
TERMINAL
I/O
FUNCTION
NUMBER
NAME
1
ENA
I
Enable input for Channel A: ENA biased LOW Disables Channel A output
regardless of INA state, ENA biased HIGH or floating Enables Channel A output,
ENA allowed to float hence it is pin-to-pin compatible with UCC2732X N/C pin.
2
INA
I
Input to Channel A: Inverting Input in UCC27523, Non-Inverting Input in UCC27524,
Inverting Input in UCC27525, OUTA held LOW if INA is unbiased or floating.

Inverting Input to Channel A: when Channel A is used in Non-Inverting
configuration connect INA- to GND in order to Enable Channel A output, OUTA held
LOW if INA- is unbiased or floating.
2
INB-
I
Inverting Input to Channel B: when Channel B is used in Non-Inverting
configuration connect INB- to GND in order to Enable Channel B output, OUTB held
LOW if INB- is unbiased or floating.
