The MAX780A provides the power switching and status

signals necessary to control two Personal Computer

Memory Card International Association (PCMCIA)

Release 2.0 card slots. The MAX780A, used in conjunc-

tion with a PC Card Interface Digital Controller, forms a

complete, minimum component count PCMCIA interface

for palmtop and notebook computers.

The MAX780A incorporates two 0V/+5V/+12V/high-

impedance power outputs for flash V

level shifters for power MOSFET control of two sepa-

rate +3.3V/+5V supplies, and two V

status signals. The MAX780A may be directly con-

nected to the control outputs from a PCMCIA digital

controller, or may be configured to use internal edge-

triggered registers for connection to the CPU data bus.

The MAX780B has all the features of the MAX780A but

omits the reference and V

MAX780C has all the features of the MAX780A but

omits the registers for the digital inputs. The MAX780D

omits the reference, the V

digital input registers.
