LF12508 - National Semiconductor

LF12508 8-Channel Analog Multiplexer

The LF11508/LF12508/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. connect a pair of independent analog inputs to one of any 4 pairs of independent analog outputs..

Features

of the LF1 1508 series and should be used whenever differential analog inputs are required. 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 charge blow-out problems associated with similar CMOS parts. The digital inputs are designed to operate from both TTL and CMOS levels while always providing a defin.
