HCF4097B is a differential 8-channel multiplexer having three binary control inputs A, B, C, and an inhibit input. The inputs permit selection of one of eight pairs of switches. A logic "1" present at the inhibit input turns all channels off. DESCRIPTION HCF4097B is monolithic integrated circuits fabricated in Metal Oxide Semiconductor technology available in SOP package.

This provision avoids permanent current flow or clamp action on the VDD supply when power is applied or removed from the HCF4097B. When switching from one address to another, some of the ON periods of the channels of the multiplexers will overlap momentarily, which may be objectionable in certain applications. Also, when a channel is turned ON or OFF by an address input, there is a momentary conductive path from the channel to VSS, which will dump some charge from any capacitor connected to the input or output of the channel. The inhibit input turning on a channel will similarly dump some charge to VSS. The amount of charge dumped is mostly a function of the signal level above VSS. Typically, at VDD - VSS = 10V, a 100 pF capacitor connected to TEST CIRCUIT the input or output of the channel will lose 3-4% of its voltage at the moment the channel turns ON or OFF. This loss of voltage is essentially independent of the address or inhibit signal transition time, if the transition time is less than 12 ms. When the inhibit signal turns a channel off, there is no change dumping of VSS. Rather, there is a slight rise in the channel voltage level (65 mV typ.) due to the capacitance coupling from inhibit input to channel input or output. Address input also couple some voltage steps onto the channel signal levels. In certain applications, the external load-resistor current may include both VDD and signal line components. To avoid drawing VDD current when switch current flows into the transmission gate inputs, the voltage drop across the bidirectional switch must not exceed 0.8V (calculated from RON values shown in ELECTRICAL CHARACTERISTICS CHART). No VDD current will flow through RL if the switch current flows into terminal 1 on the HCF4097B.
