ADG3257BRQZ-REEL

ADG3257BRQZ-REEL is a CMOS bus switch comprised of four 2:1 multiplexers/demultiplexers with high-impedance outputs. This device is manufactured on a CMOS process. It provides low power dissipation yet high switching speed and very low on-resistance, allowing the inputs to be connected to the outputs without adding propagation delay or generating additional ground bounce noise. It operates from a single 3.3V/5V supply. This switch is bidirectional when on. In the off-state, signal levels are blocked upto the supplies. When the power supply is off, the switches remain in the off state, isolating Port A and Port B. This bus switch is suited to both switching and level translation applications. It can be used in applications requiring level translation from 3.3V to 2.5V when powered from 3.3V. It is used in applications such as bus switching, bus isolation, level translation, and memory switching/interleaving.

• Level translation operation, switches remain in the off state when power is off
• Standard 3257 type pinout, single 3.3V/5V supply operation
• On resistance is 2 ohm typical at (VA = 0V, IO = 15mA, 8mA, TA = 25°C)
• Ultralow quiescent supply current is 1nA maximum at (digital inputs = 0V or VCC)
• Input leakage current is ±1μA maximum at (0 ≤ VIN ≤ 3.6V, VCC = 3.3V ±10%, GND = 0V)
• Bus disable time is 3.5ns typical at (CL = 50pF, RL = 500 ohm)
• Control input capacitance is 4pF typical at (f = 1MHz, VCC = 5V ±10%, GND = 0V)
• Operating temperature range from -40°C to +85°C
• 16-lead QSOP package
