LF2650

Analog Switches LF1650/LF2650/LF3650 quad JFET analog switch general description The LF1650/LF2650/LF3650 is a monolithic combination of bipolar and JFET technology producing the industry's first one chip quad FET switch_ A unique circuit technique is employed to maintain a constant RON over the analog voltage range. The input is designed to operate from minimum TTL levels. and switch operation also ensures a break before make action. features Constant ON resistance for signals ±10V and 100 kHz < tOFF tON. break before make action Open switch isolation at 1.0 MHz < 1.0 nA leakage in OFF state -50 dB TTL. DTL. RTL direct drive compatibility Single disable pin turns all sWitches in package OFF The LF1650/LF2650/LF3650 is designed to operate from ±15V supplies and swing a ±1 OV analog signal. The FET SWitches can be used wherever a dc to medium frequency analog signal needs to be controlled . I'"' ::!l 0) oC1I ....... I'"' "T1 N 0) oC1I ....... I'"' "T1 ...
