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 the pin-to-pin compatibility 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.

3

GND

-

Ground: All signals referenced to this pin.

4

INB

I

Input to Channel B: Inverting Input in UCC27523, Non-Inverting Input in UCC27524,

Non-Inverting Input in UCC27525, OUTB held LOW if INB is unbiased or floating.

5

OUTB

O

Output of Channel B

6

VDD

I

Bias supply input

7

OUTA

O

Output of Channel A

8

ENB

I

Enable input for Channel B: ENB biased LOW Disables Channel B output

regardless of INB state, ENB biased HIGH or floating Enables Channel B output,

ENB allowed to float hence the pin-to-pin compatibility with UCC2732X N/C pin.

FUNCTION

NUMBER

NAME

1

INA-

I

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.

3

GND

-

Ground: All signals referenced to this pin.

6

OUTA

I

Output of Channel A

7

INB+

O

Non-Inverting Input to Channel B: When Channel B is used in Inverting

configuration, connect INB+ to VDD in order to Enable Channel B output, OUTB held

LOW if INB+ is unbiased or floating.

8

INA+

I

Non-Inverting Input to Channel A: When Channel A is used in Inverting

configuration, connect INA+ to VDD in order to Enable Channel A output, OUTA held

LOW if INA+ is unbiased or floating.
