Single and Dual
PCMCIA Protected
3.3V/5V VCC Switches
U FEATURES DESCRIPTIO в– The LTCВ®1470 switches the VCC pins of a Personal Computer Memory Card International Association (PCMCIA)
card slot between three operating states: OFF, 3.3V and
5V. Two low RDS(ON) N-channel power MOSFETs are
driven by a built-in charge pump which generates a
voltage higher than the supply voltage to fully enhance
each switch when selected by the input control logic. в–
