_______________General Desc ription
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
PP
programming,
level shifters for power MOSFET control of two sepa-
rate +3.3V/+5V supplies, and two V
PP
power-ready
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
PP
valid indicators. The
MAX780C has all the features of the MAX780A but
omits the registers for the digital inputs. The MAX780D
omits the reference, the V
PP
valid indicators, and the
digital input registers.
