The LTC®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 controller, 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 N-channel 3.3V/5V VCC switching. The 12V regulator can be shut down when 12V is not required at VPPOUT. 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.
