LM1038

The LM1038 is a dual, electronically controlled, four-channel analog switch with an internal muting facility. Its features make it ideal for stereo source selection in audio equipment and for use in a wide range of industrial, automotive, multiplexing or sampling applications. Channel selection is achieved via two logic data pins with clock enabled latches. Muting is also selectable under clock control.

The features of LM1038 can be summarized as (1)wide supply voltage range, 5V-28V; (2)low distortion, 0.04% typical; (3)high input impedance; (4)low output impedance; (5)TLL compatible control inputs; (6)very low control current; (7)2 control pins accept BCD input pulses; (8)clock enable input may be strobed from a bus.

The absolute maximum ratings of LM1038 are (1)supply voltage: 28V; (2)pin 7 input current: 5 mA; (3)operating temperature range: - 20°C to + 70°C; (4)storage temperature range: -65°C to + 150°C; (5)power dissipation (Note 1): 1.3W; (6)lead temperature (soldering, 10 sec.): 260°C.(If millitary/aerospace specified devices are required, please contact the national semiconductor sales office/Distributore for availability and specitications. )
