SVLAAL/I Quad SPDT CMOS Analog Switch ee. General Description The MAX333 is a quad single-pole-double-throw (SPDT) analog switch. These four independent switches can be operated with bipolar power supplies ranging from +5V to +18V, or single-ended power supplies of +10V to +30V. The MAX333 has break-before-make switching, (200ns typical), a maximum turn-off time of 500ns, and a maximum turn-on time of 1000ns. The MAX333 is ideal for portable operation since quiescent current is only 250uA maximum with all inputs high, and less with all inputs low. Logic inputs are fully 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 anywhere between the supply volt- ages without damage. The MAX333 is a low-cost replacement for a DG211/DG212 pair when used as a quad SPOT switch. _ .. ___tssti(tstStC A ipipsiicattiornss Winchester Disk Drives Test Equipment Communications Systems PBX, PABX Head up Displays Portable Instruments ___... ~ Pin Configuration TOP VIEW IN1 ir not [2 | 20} IN4 19 | NO4 i com: [3] ner [4 | ie GND [6 | nc2 [7] comz [8 | no2 [9] ie VIA XI svi MAX333 ft t IN2_ [10] 18 | coma r17] Nea 16| Vv - NC.

Note 6: Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing. Protecting Against Fault Conditions Fault conditions occur when power supplies are turned off when input signals are still present or when over voltages occur at the inputs during normal operation. In either case, source-to-body diodes can be forward biased and conduct current from the signal source. If this current is required to be kept to low (wA) levels then the addition of external protection diodes is recommended. To provide protection for over-voltages up to 20V above the supplies, 1N4001 or 1N914 type diodes should be placed in series with the positive and negative supplies. The addition of these diodes will reduce the analog signal range to 1 volt below the positive supply and 1 volt above the negative supply. cOM1 oll GND ~+ NOTE: NCx IS CONNECTED TO COMx WHEN INx IS LOW.
