MAX4547EEE+

The MAX4547EEE+ is a dual, low voltage, bidirectional RF/video switch in 16 pin QSOP package. It is a low voltage T-switches designed for switching RF and video signals from DC to 300MHz in 50 ohm and 75ohm systems. Each switch is constructed in a “T” configuration ensuring excellent high frequency off isolation of -82dB at 10MHz. It can handle rail to rail analogue signals in either direction. On-resistance (20 ohm max) is matched between switches to 1ohm max and is flat (0.5ohm max) over the specified signal range, using ±5V supplies. The off leakage current is less than 5nA at +25°C and 50nA at +85°C. All digital inputs have 0.8V/2.4V logic thresholds ensuring both TTL and CMOS logic compatibility when using ±5V or a single +5V supply. This device is used in RF switching, video signal routing, high speed data acquisition test equipment ATE equipment and networking.

• Supply voltage range is 2.7V to 12V, ±2.7V to ±6V
• Operating temperature range from -40°C to 85°C
• Two SPDT switches
• Low power consumption of 1μW
• Pin compatible with industry standard DG540, DG542, DG643 IC
• Greater than 2KV ESD protection per method 3015.7
• Low 50 ohm insertion loss is -1dB at 100MHz
