Easily Interfaced: prising four independently selectable switches. On-chip latches Digital inputs are latched with a WR signal for microprocessor facilitate microprocessor interfacing. They are designed on an interfacing. A SV regulated supply is internally generated enhanced LCMOS process which gives an increased signal permitting wider tolerances on the supplies without affecting handling capability of + 15V. These switches also feature high the TTL digital input switching levels. switching speeds and low Ron. 2. Single Supply Operation: The ADG221 and ADG222 consist of four SPST switches. They For applications where the analog signal is unipolar (OV to differ only in that the digital control logic is inverted. All devices 15V), the switches can be operated from a single + 15V exhibit break before make switching action. Inherent in the supply. design is low charge injection for minimum transients when 3. Low Leakage: switching the digital inputs. Leakage currents in the range of SO0pA make these switches suitable for high precision circuits. The added feature of Break-before-Make switching allows for multiple outputs to be tied together for multiplexer applications while keeping leakage errors to a minimum. __ | aDG221 ADG222 SWITCH WR | IN IN CONDITION 0 0 1 ON 0 1 0 OFF 1 x xX Retains Previous Switch Condition Tablel.
