cd4066a typ s cos/mos quad bilateral switch for transmission or multiplexing of analog or digital signals rca c04066a is a quad bilateral switch intended for the transmission or multiplex- ing of analog or digital signals. it is pin-for- pin compatible with rca-c04016, but ex- hibits a much lower on rttsistance. in addi- tion, the on resistance is relatively constant over the full input-signal range. the c04066a consists of four independent bilateral switches. a single control signal is required per switch. both the p and the n device in a given switch are biased on or off simultaneously by the control signal. as shown in fig. 1, the well of the n-channel device on each switch is either tied to the input when the switch is on or to vss when the switch is off. this configuration elimi- nates the varration of the switch-transistor threshold voltage with input signal, and thus keeps the on resistance low over the full operating-signal range. the advantages over single-channel switches include peak inputsignal voltage swings equal to the full supply voltage, and more constant on impedance over the input- signal range. for sample-and-hold applica- tions, however, the c04016is recommended. these types are supplied in 14-lead hermetic dual-in-line ceramic packages (0 and f suffixes), 14-lead dual-in-line plastic pack- age (e suffix), 14-lead ceramic flat package (k suffix). and in chip form (h suffix). special considerations - cd4066a 1. i n applications where separate power sources are used to drive voo and the signal inputs, the voo current capability should exceed voo/rl (rl = effective external load of the 4 c04066a bilateral switches). this provision avoids any permanent current flow or clamp action on the voo supply when power is applied or removed from c04066a. 2. i n certain applications, the external load resistor current may include both voo and signal'line components. to avoid drawing voo current when switch cur rent flows into terminals 1, 4, 8, or 11, the voltage drop across the bidirectional switch. must not exceed 0.8 volt (calcu- tated from ron values shown). no voo current will flow through rl if the switch current flows into terminals 2, 3,9, or 10. 3. minimum bilateral switch output load resistance is 100 n. features: ? 15-v digital or 7.5-v peak-to-peak switching ? 80n typical on resistance for 15-v operation ? switch on resistance matched to within 5 n over 15-v signal-input range ? on resistance flat over full peak-to-peak signal range ? high on/off output-voltage ratio: 65 db typo @ f is = 10 khz, rl = 10 kn ? high degree of linearity: < 0.5% distor- tion typo @ fis = 1 khz, vis = 5 v p _ p , voo-vs~10v'~l=10kn ? extremely low of f switch leakage result- ing in very low offset current and high effective off resistance: 10 pa typo @ voo-vss = 10 v, ta = 25c ? extremely high control input impedance (control circuit isolated from signal circuitl: 10 12 n typo ? low crosstalk between switches: -50 db typo @ fis = 0.9 mhz, rl = 1 kn normal operation control-line biasing switch on.1o\: '1-' voo cd4066a functional diagram ? matched control-input to signal-output capacitance: reduces output signal transients ? frequency response, switch on = 40 mhz (typ.) ? quiescent current specified to 15-v ? maximum control input leakage current of 1-~a at 15-v (full package- temperature range) signal-level rang_ vss s vi. :svoo .. * all control inputs are protected by cos/mos protection network '_m'b;, 92cs-21628r2 vss fig. , - schematic diagram of , of 4 identical switches bnd its buociated control circuitry. maximum ratings, absolute-maximum values: storage temperature range (tstgl .. operating temperature range (tal ........... -65 to +125c package types d. f, k, h. . ........ . ........... -55 to +125c package type e . . . . . . . . . . . . . . . . . . -40 to +85 c dc supply voltage range, v dd (voltages referenced to v ss ) . . . . . . . . . . . . . ................... -0.5 to +15 v input current (transmission gate incl.). . . . . . . . . . . . . . . . . . . 10 ma power dissipation per package. for t a c -40 to +60c (package type e i " . . . . . . . . . ........
