LTC1314/LTC1315 PCMCIA Switching Matrix with Built-In N-Channel VCC Switch Drivers Features s s s s s s s s s DESCRIPTIO Output Current Capability: 120m A External 12V Regulator Can Be Shut Down Built-In N-Channel VCC Switch Drivers Digital Selection of 0V, VCCIN, VPPIN or Hi-Z 3.3V or 5V VCC Supply Break-Before-Make Switching 0.1µA Quiescent Current in Hi-Z or 0V Mode No VPPOUT Overshoot Logic patible with Standard PCMCIA Controllers The LTC®1314/LTC1315 provide the power switching necessary to control Personal puter Memory Card International Association (PCMCIA) Release 2.0 card slots. When used in conjunction with a PC card interface controller, these devices form a plete minimum ponent count interface for palmtop, pen-based and notebook puters. 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 patible 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. , LTC and LT are registered trademarks of Linear Technology Corporation.
