FSA1256 • FSA1256A • FSA1257 • FSA1257A • FSA1258 • FSA1258A Low RON Low Voltage Dual SPST Analog Switch with Low ICCT “A” Option March 2004 Revised April 2005 FSA1256 • FSA1256A • FSA1257 • FSA1257A • FSA1258 • FSA1258A Low RON Low Voltage Dual SPST Analog Switch with Low ICCT “A” Option General Description The FSA1256, FSA1256A, FSA1257, FSA1257A, FSA1258, and FSA1258A are high performance dual Single Pole/Single Throw (SPST) analog switches. All devices feature ultra low RON of 1.1: maximum at 4.5V VCC. The FSA1256, FSA1257, and FSA1258 operate over a wide VCC range of 1.65V to 5.5V. The FSA1256A, FSA1257A, and FSA1258A operation range is 2.7V to 5.5V. These devices are fabricated with sub-micron CMOS technology to achieve fast switching speeds and are designed for break-before-make operation. The select input is TTL level compatible. The FSA1256 and FSA1256A feature two Normally Open (NO) switches. The FSA1257 and FSA1257A feature two Normally Closed (NC) switches. The FSA1258 and FSA1258A have one NO switch and one NC switch. Features s FSA1256A, FSA1257A, FSA1258A feature low ICCT when S Input is lower than VCC s Maximum 1.1: On Resistance (RON) for 4.5V supply s 0.4: max RON flatness for 4.5V supply s Space saving Pb-Free MicroPak¥ packaging s Broad VCC operating range: • FSA1256, FSA1257, FSA1258: 1.65V to 5.5V • FSA1256A, FSA1257A, FSA1258A: 2.7V to 5.5V s Fast turn-on and turn-off time s FSA1258, FSA1258A feature break-before-make enable circuitry s Over-voltage tolerant TTL compatible control input Ordering Code: Product Order Number FSA1256L8X FSA1256AL8X FSA1257L8X FSA1257AL8X FSA1258L8X FSA1258AL8X Package Number MAC08A MAC08A MAC08A MAC08A MAC08A MAC08A Code Top Mark EB FN EC FP ED FS Pb-Free 8-Lead MicroPak, 1.6 mm Wide Pb-Free 8-Lead MicroPak, 1.6 mm Wide Pb-Free 8-Lead MicroPak, 1.6 mm Wide Pb-Free 8-Lead MicroPak, 1.6 mm Wide Pb-Free 8-Lead MicroPak, 1.6 mm Wide Pb-Free 8-Lead MicroPak, 1.6 mm Wide 5K Units on Tape and Reel 5K Units on Tape and Reel 5K Units on Tape and Reel 5K Units on Tape and Reel 5K Units on Tape and Reel 5K Units on Tape and Reel Package Description Supplied As Pb-Free package per JEDEC J-STD-020B.
