C1
Pin-strap input that selects edge-triggered register or direct digital inputs. Tying C2 to
VCCIN makes the logic inputs edge triggered; inputs to pins 4-11 are clocked in on the
rising edge of WR. Tying C2 to GND allows control signals to be directly applied to the
logic inputs on pins 4-11. Connect to GND for MAX780C.
Pin-strap input that selects one of two logic decode modes for the digital inputs. See Tables 1-3.
Write pulse input. When C2 is tied to VCCIN, a rising edge on WR clocks in the V

GND for MAX780C.
Logic inputs that control the voltage on AVPP.
Logic inputs that control the voltage on BVPP.
Logic inputs that control the state of the MOSFET gate drivers ADRV3 and ADRV5.
Logic inputs that control the state of the MOSFET gate drivers BDRV3 and BDRV5.
Open-drain gate driver outputs that control the MOSFETs that switch the V
B to 0V, 3.0V/3.3V, or 5V.
Open-drain gate driver outputs that control the MOSFETs that switch the V
A to 0V, 3.0V/3.3V, or 5V.
Logic-level power-ready output that stays low as long as BVPP is greater than 11.05V
(MAX780A and MAX780C only). Make no connection to this pin for MAX780B.
Logic-level power-ready output that stays low as long as AVPP is greater than 11.05V
(MAX780A and MAX780C only). Make no connection to this pin for MAX780B.
Logic input that shuts the MAX780 down to a low supply-current state when brought
low. Asserting SHDN forces ADRV3, BDRV3, ADRV5, BDRV5, REF, AGPI, and BGPI
low. All V

No connect. Not internally connected.
1.25V reference voltage output (MAX780A and MAX780C only). Make no connection to
