1314/LTC1315 provide the power switching
necessary to control Personal Computer Memory Card
International Association (PCMCIA) Release 2.0 card slots.
When used in conjunction with a PC card interface control-
ler, these devices form a complete minimum component
count interface for palmtop, pen-based and notebook
computers.
The LTC1314/LTC1315 provide 0V, 3.3V, 5V, 12V and
Hi-Z power output for flash VPP programming. A built-in
charge pump produces 12V of gate drive for inexpensive

. All
digital inputs are TTL compatible and interface directly
with industry standard PC card interface controllers.
The LTC1314 is available in 14-pin SO and the LTC1315 in
24-pin SSOP.
