The Maxim Hl-201 monolithic CMOS quad single-pole-single-throw (SPST) analog switch is a plug-in upgrade for the Harris Hl-201. Maxim has eliminated the need for a VREF supply, which is normally required for operation with power supplies other than ±15V. And Maxim's part consumes 1/4 the power (4mW typ), making it better suited for portable applications. Maxim's switch can be continuously operated with power supplies ranging from ±4.5V to ±18V, or single supplies over a range of +5V to +30V. Each switch can be independently selected and features fast switching (ton= 260ns, toff= 100ns typ) and low on resistance (45Q typ). Maxim guarantees these switches will not latchup if the power supplies are disconnected with switch input signals still present. Logic inputs are both CMOS and TTL compatible without the need for pull-up resistors.
