Revised July 2004 FSA1156 • FSA1157 Low RON Low Voltage SPST Analog Switch General Description Features 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. ■ Maximum 0.9Ω On Resistance (RON) for 4.5V supply at 25°C ■ 0.3Ω maximum RON flatness for 4.5V supply ■ Broad VCC operating range: 1.65V to 5.5V ■ Fast turn-on and turn-off time ■ Over-voltage tolerant TTL compatible control input ■ Available in SC70 and MicroPak space saving surface mount packages Ordering Code: Product Code Package Top Mark Number FSA1156P6 156 MAA06A 6-Lead SC70, EIAJ SC88, 1.25mm Wide FSA1156P6X 156 MAA06A 6-Lead SC70, EIAJ SC88, 1.25mm Wide 3k Units on Tape and Reel FSA1156L6X EH MAC06A 6-Lead MicroPak, 1.0mm Wide 5k Units on Tape and Reel FSA1157P6 157 MAA06A 6-Lead SC70, EIAJ SC88, 1.25mm Wide 250 Units on Tape and Reel FSA1157P6X 157 MAA06A 6-Lead SC70, EIAJ SC88, 1.25mm Wide 3k Units on Tape and Reel FSA1157L6X EJ MAC06A 6-Lead MicroPak, 1.0mm Wide 5k Units on Tape and Reel Order Number Package Description Supplied As 250 Units on Tape and Reel MicroPak is a trademark of Fairchild Semiconductor Corporation. © 2004 Fairchild Semiconductor Corporation DS500842 www.fairchildsemi.com FSA1156 • FSA1157 Low RON Low Voltage SPST Analog Switch November 2003 FSA1156 • FSA1157 Analog Symbols Pin Assignments for SC70 Package Pin Assignments for MicroPak (Top View) FSA1156 (Normally Open) (Top Through View) FSA1156 (Normally Open) Pin Assignments for SC70 Package Pin Assignment for MicroPak (Top View) FSA1157 (Normally Closed) (Top Through View) FSA1157 (Normally Closed) Truth Table Pin Descriptions Control Input Function of Function of Pin Name (S) FSA1156 FSA1157 A, B Data Ports L OFF ON S Control Input H ON OFF NC No Connect H = HIGH Logic Level L = LOW Logic Level www.fairchildsemi.com 2 Description Recommended Operating Conditions (Note 3) −0.5V to +6.0V Supply Voltage (VCC) −0.5V to VCC +0.5V Switch Voltage (Note 2) Supply Voltage (VCC) −0.5V to +6.0V Input Voltage (VIN) (Note 2) 1.65V to 5.5V Control Input Voltage (Note 3) 0V to VCC 0V to VCC Input Diode Current −50 mA Switch Input Voltage Switch Current 200 mA Operating Temperature −40°C to 85°C Thermal Resistance θJA in Still Air Peak Switch Current (Pulsed at 1mS duration, 350°C/W SC70 package <10% Duty Cycle) 400 mA Power Dissipation at 85°C SC70 package 180 mW Storage Temperature Range (TSTG) Note 1: The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum rating.
