                                                ISL43L840IRZ-T Overview
Shipping overseas is convenient with the electronic component packed in 16-VFQFN Exposed Pad. This high-reliability packaging method uses advanced packaging methods Tape & Reel (TR). There is an analog multiplexer mounted in position Surface Mount. Multiplexer and demultiplexer circuits have a number 4:1. Operation at a temperature around -40°C~85°C TA. These analog multiplexers are built based on SP4T switching circuits. There are 2 circuits in this multiplexer. This analogue multiplexer requires a voltage of 1.6V~3.6V when it drains from a single voltage supply. It is possible to purchase a 16-QFN (3x3) package from suppliers.
