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.
TERMINAL FUNCTIONS (UCC27526)
TERMINAL
I/O 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.
4 OUTB I Output of Channel B
5 VDD O Bias Supply Input
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.
