DATASHEET ISL43L840 FN6096 Rev 1.00 Ultra Low ON-Resistance, Low-Voltage, Single Supply, Dual 4 to 1 Analog October 12, 2004 Multiplexer The Intersil ISL43L840 device is a precision, bidirectional, Features analog switch configured as a dual 4-channel ON Resistance (R ) ON multiplexer/demultiplexer, designed to operate from a single - V+ = +3.0V . 0.5 +1.6V to +3.6V supply. - V+ = +1.8V 0.62 ON resistance is 0.5 with a +3V supply and 0.62 with a R Matching Between Channels .0.12 ON single +1.8V supply. Each switch can handle rail to rail analog signals. The off-leakage current is only 4nA max at R Flatness Across Signal Range 0.056 ON +25C and 30nA max at +85C with a +3.3V supply. Single Supply Operation . +1.6V to +3.6V All digital inputs are 1.8V logic-compatible when using a Low Power Consumption (PD) <0.2W single +3V supply. Fast Switching Action (V = +3V) S The ISL43L840 is a dual 4 to 1 multiplexer device that is -t . 19ns RANS offered in a 16 Ld TSSOP and 16 Ld 3x3 QFN packages.
