• Description: PCMCIA Switching Matrix with Built-In N-Channel VCC Switch Drivers
• Manufacturer: LINER [Linear Technology]

BLOCK
LTC1315
VPP
SHDN (Pins 2, 8): Shutdown Outputs. When the output is
high, the external 12V regulator can be shut down to
conserve power consumption.
EN0, EN1 (Pins 3, 4, 9, 10): Logic inputs that control the
voltage output on VPP
compatible with TTL/CMOS levels. Refer to the Truth
Table.
V
MOSFET gate driver DRV3. ESD protection device limits
input excursions to 0.6V below ground.
V
MOSFET gate driver DRV5. ESD protection device limits
input excursions to 0.6V below ground.

DRV5, DRV3 (Pins 13, 14, 19, 20): Gate driver outputs
that control the external MOSFETs that switch the V
of card slot to Hi-Z, 3.3V, or 5V.
V
These pins supply the power to the control logic and the
charge pumps and must be continuously powered.
GND (Pins 16, 22): Ground Connections.
