DescriptionThe MAX4545/MAX4546/MAX4547 are low-voltage T-switches designed for switching RF and video signals from DC to 300MHz in 50Ωand 75Ω systems. The MAX4545 contains four normally open single-pole/single- throw (SPST) switches. The MAX4546 contains two dual SPST switches (one normally open, one normally closed.) The MAX4547 contains two single-pole/double-throw (SPDT) switches.
Each switch MAX4545 is constructed in a "T" configuration, ensuring excellent high-frequency off isolation and crosstalk of -80dB at 10MHz. They can handle Rail-to-Rail®analog sig- nals in either direction. On-resistance (20Ωmax) is matched between switches to 1Ωmax and is flat (0.5Ωmax) over the specified signal range, using ±5V supplies.The off leakage current is less than 5nA at +25°C and 50nA at +85°C.
The MAX4545 can operate with dual power sup- plies ranging from ±2.7V to ±6V or a single supply between +2.7V and +12V. All digital inputs have 0.8V/2.4V logic thresholds, ensuring both TTL- and CMOS-logic com- patibility when using ±5V or a single +5V supply.
