MAX4947ETG+

The MAX4947ETG+ belongs to MAX4947/MAX4948 family analog switches operate from a single +1.8V to +5.5V supply. The MAX4947 has three logic inputs to control the switches in pairs. The MAX4948 has one logic input and an enable input (EN)to disable the switches. The MAX4947/MAX4948 are available in small 24-pin (4mm x 4mm)TQFN and 25-bump (2.5mm x 2.5mm)chip-scale packages (UCSP). These switches feature a low 30pF (typ)capacitance for high-speed data switching applications. The MAX4947 is a triple double-pole/double-throw (DPDT)switch, and the MAX4748 is a hex single-pole/doublethrow (SPDT)switch with one control logic input.

The features of MAX4947ETG+ can be summarized as (1)multiplex SDIO or memory stick interfaces; (2)1.8V to 5.5V supply voltage range; (3)low on-resistance 4 (typ); (4)low-capacitance switches, 30pF (typ); (5)rail-to-rail signal handling; (6)small 25-bump UCSP (2.5mm x 2.5mm)and 24-TQFN (4mm x 4mm).

The absolute maximum ratings of MAX4947ETG+ are (1)VCC to GND: -0.3V to +6.0V; (2)all other pins to GND (Note 1):-0.3V to VCC + 0.3V; (3)continuous current NO_, NC_, COM_: ±100mA; (4)peak current NO_, NC_, COM_ (pulsed at 1ms, 50% Duty Cycle):±200mA; (5)(pulsed at 1ms, 10% Duty Cycle):±300mA; (6)continuous power dissipation (TA = +70°C)25-Bump UCSP (derate 12.2mW/°C above +70°C): 976mW/ 24-Pin TQFN (derate 20.8mW/°C above +70°C): 1667mW; (7)operating temperature range: -40°C to +85°C; (8)junction temperature: 150°C; (9)storage temperature range: -65°C to +150°C; (10)bump temperature (soldering)Infrared (15s): +220°C; (11)vapor phase (60s): +215°C; (12)lead temperature (soldering): +300°C.
