Product Description

Product Details
The ADG3257 is a CMOS bus switch comprising four 2:1 multiplexer/demultiplexers with high impedance outputs. The device is manufactured on a CMOS process, which provides low power dissipation yet gives 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.
The ADG3257 operates from a single 3.3 V/5 V supply. The control logic for each switch is shown in the Truth Table in the data sheet. These switches are bi-directional when ON. In the OFF condition, signal levels up to the supplies are blocked.
This Bus Switch is suited to both switching and level translation application. It may be used in applications requiring level translation from 3.3 V to 2.5V when powered from 3.3 V. Additionally, with a diode connected in series with 5 V VDD, the ADG3257 may also be used in applications requiring 5 V to 3.3 V level translation.
