



The FSA2457 is a bi-directional, low-power, dual
double-pole double-throw (4PDT) analog switch targeted
at dual 1-bit SIM/SD/MMC card and/or GPS signal
multiplexing. It is optimized for switching the WLAN-SIM
data and control signals at 52Mbps.
Low On Capacitance for Data Path: 12pF Typical
Low On Resistance for Data Path: 5Ω Typical
Low Power Quiescent Consumption: 1μA Maximum
Wide -3db Bandwidth: > 160MHz
Packaged in Green 16-Lead UMLP (1.8 x 2.6mm)
4kV JEDEC: JESD22-A114 HBM
2kV JEDEC: JESD22-C101 CDM
Applications

The FSA2457 is compatible with the requirements of 1bit SIM/SD/MMC cards and is ideal for interfacing to
GPS baseband processors. The FSA2457 features a
low on capacitance (CON) of 12pF to ensure high-speed
data transfer.
The FSA2457 contains special circuitry that minimizes
current consumption even when the control voltage
applied to the SEL pin is lower than the supply voltage
(VCC). This feature is especially valuable in ultra-portable
applications, such as cell phones; allowing direct
interface with the general-purpose I/Os of the baseband
processor. Other applications include switching and
connector sharing in portable cell phones, PDAs, digital
cameras, printers, and portable GPS systems.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Note:
1. The input and output negative ratings may be exceeded if the input and output diode current ratings are
observed.
Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to Absolute Maximum Ratings.
