FSA1156

FSA1156 • FSA1157 Low RON Low Voltage SPST Analog Switch November 2003 Revised January 2005 FSA1156 • FSA1157 Low RON Low Voltage SPST Analog Switch General Description The FSA1156 and FSA1157 are high performance Single Pole/Single Throw (SPST) analog switches. The devices feature ultra low RON of 0.75Ω (typical) and will operate over the wide VCC range of 1.65V to 5.5V. The devices are fabricated with sub-micron CMOS technology to achieve fast switching speeds. The select input is TTL level compatible. The FSA1156 has Normally Open operation and the FSA1157 has Normally Closed operation. Features s Maximum 0.9Ω On Resistance (RON) for 4.5V supply at 25°C s 0.3Ω maximum RON flatness for 4.5V supply s Broad VCC operating range: 1.65V to 5.5V s Fast turn-on and turn-off time s Over-voltage tolerant TTL compatible control input s Available in SC70 and MicroPak space saving surface mount packages s Available in Lead (Pb) Free MicroPak packaging Ordering Code: Product Order Number FSA1156P6 FSA1156P6X FSA1156P6X_NL FSA1156L6X FSA1157P6 FSA1157P6X FSA1157L6X Code Top Mark 156 156 156 EH 157 157 EJ Package Number MAA06A MAA06A MAA06A MAC06A MAA06A MAA06A MAC06A 6-Lead SC70, EIAJ SC88, 1.25mm Wide 6-Lead SC70, EIAJ SC88, 1.25mm Wide Pb-Free 6-Lead MicroPak, 1.0mm Wide 6-Lead SC70, EIAJ SC88, 1.25mm Wide 6-Lead SC70, EIAJ SC88, 1.25mm Wide Pb-Free 6-Lead MicroPak, 1.0mm Wide 250 Units on Tape and Reel 3k Units on Tape and Reel 5k Units on Tape and Reel 250 Units on Tape and Reel 3k Units on Tape and Reel 5k Units on Tape and Reel Package Description Supplied As Pb-Free 6-Lead SC70, EIAJ SC88, 1.25mm Wide 3k Units on Tape and Reel Pb-Free package per JEDEC J-STD-020B.
