The MAX333A is a precision, quad, single-pole double-
throw (SPDT) analog switch. The four independent
switches operate with bipolar supplies ranging from
±4.5V to ±20V, or with a single-ended supply between
+10V and +30V. The MAX333A offers low on resistance
(less than 35Ω), guaranteed to match within 2Ω between
channels and to remain flat over the analog signal range
(∆3Ω max). It also offers break-before-make switching
(10ns typical), with turn-off times less than 145ns and
turn-on times less than 175ns. The MAX333A is ideal for
portable operation since quiescent current runs less
than 50µA with all inputs high or low.
This monolithic, quad switch is fabricated with Maxim’s
new improved silicon-gate process. Design improvements
guarantee extremely low charge injection (10pC), low
power consumption (3.75mW), and electrostatic discharge
(ESD) greater than 2000V.
Logic inputs are TTL and CMOS compatible and guaranteed
over a +0.8V to +2.4V range—regardless of supply voltage.
Logic inputs and switched analog signals can range any-
where between the supply voltages without damage.
