Description

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 conjunction 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 VPP programming, level shifters for power MOSFET control of two separate +3.3V/+5V supplies, and two VPP power-ready status signals. The MAX780A may be directly connected 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 VPP 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 VPP valid indicators, and the digital input registers.
