ADG508A

The ADG508A is a kind of CMOS monolithic analog multiplexer with 8 channels. The device switches one of 8 inputs to a common output depending on the state of three binary addresses and an enable input. The device has TTL and 5 V CMOS logic compatible digital inputs. ADG508A is designed on an enhanced LC2MOS process which gives an increased signal capability of VSS to VDD and enables operation over a wide range of supply voltages.

There are some features of ADG508A as follows: (1)44 V supply maximum rating; (2)VSS to VDD analog signal range; (3)single supply specifications; (4)wide supply ranges (10.8 to 16.5 V); (5)extended plastic temperature range (-40 to +85); (6)low power dissipation (28 mW max); (7)low leakage (20 pA typ); (8)available in 16-lead DIP/SOIC and 20-lead PLC/LCCC packages; (9)superior alternative to: DG508A, HI-508 and DG509A, HI-509.

The last one is about the absolute maximum ratings of ADG508A(Ta=25): (1)VDD to VSS: 44 V; (2)VDD to GND: 25 V; (3)VSS to GND: -25 V; (4)analog inputs, voltage at S, D: VSS-2 V or VDD+2 V or 20 mA, whichever occurs first; (5)continuous current, S or D: 20 mA; (6)pulsed current S or D, 1 ms duration, 10% duty cycle: 40 mA; (7)digital inputs, voltage at A, EN: VSS-4 to VDD+4 V or 20 mA, whichever occurs first; (8)power dissipation (any package): 470 mW when up to +75; (9)operating temperature range: commercial (K version): -40 to +85;industrial (B version): -40 to +85; extended (T version): -55 to 125; (10)storage temperature: -65 to 150; (11)lead temperature (soldering, 10secs): +300.
