General Description
The LF13508 is an 8-channel analog multiplexer which connects the output to 1 of the 8 analog inputs depending on the state of a 3-bit binary address An enable control allows disconnecting the output thereby providing a package select function This device is fabricated with National’s BI-FET technology which provides ion-implanted JFETs for the analog switch on the same chip as the bipolar decode and switch drive circuitry This technology makes possible low constant ‘‘ON’’ resistance with analog input voltage variations This device does not suffer from latch-up problems or static char
