Revised July 2004 FSAT66 Low Voltage Single SPST Normally Open Analog Switch with TTL Compatible Control Input General Description Features The FSAT66 is a high speed single pole/single throw normally open Analog Switch with a TTL compatible control input and is fabricated on a sub-micron CMOS process. ■ Space saving SC70 5-lead package The low On Resistance of the switch allows input to be connected to output with minimal propagation delay and without generating additional ground bounce noise. The device is organized as a 1-bit switch with a switch enable (OE) signal. When OE is HIGH, the switch is on and Port A is connected to Port B. When OE is LOW, the switch is open and a high-impedance state exists between the two ports. ■ Ultra small MicroPak leadless package ■ Broad VCC Operating Range 1.65V to 5.5V ■ Rail-to-rail signal handling ■ 5Ω switch connection between two ports ■ Minimal propagation delay through the switch ■ Low ICC ■ Zero bounce in flow-through mode ■ Control input compatible with TTL input levels ■ >250 MHz–3dB bandwidth Ordering Code: Product Order Package Code Number Number Top Mark MA05B AT66 FSAT66P5X MAA05A T66 5-Lead SC70, EIAJ SC-88a, 1.25mm Wide 3K Units on Tape and Reel FSAT66L6X MAC06A EF 6-Lead MicroPak, 1.0mm Wide 5K Units on Tape and Reel FSAT66M5X (Preliminary) Package Description 5-Lead SOT23, JEDEC MO-178, 1.6mm Supplied As 3K Units on Tape and Reel MicroPak is a trademark of Fairchild Semiconductor Corporation. © 2004 Fairchild Semiconductor Corporation DS500862 www.fairchildsemi.com FSAT66 Low Voltage Single SPST Normally Open Analog Switch with TTL Compatible Control Input April 2003 FSAT66 Logic Symbol Analog Symbol Pin Descriptions Connection Diagrams Pin Names Description OE Switch Enable Input A Bus A I/O B Bus B I/O NC No Connect Pin Assignments for SOT23 and SC70 Function Table OE B0 Function L High-Z State Disconnect A0 Connect H H = HIGH Logic Level (Top View) Pad Assignments for MicroPak L = LOW Logic Level (Top Thru View) www.fairchildsemi.com 2 Recommended Operating Conditions (Note 3) −0.5V to +7.0V Supply Voltage (VCC) −0.5V to VCC + 0.5V DC Switch Voltage (VS) Power Supply Voltage (VCC) −0.5V to +7.0V DC Input Voltage (VIN) (Note 2) 0V to 5.5V Switch Input Voltage (VIN) 0V to VCC −50 mA Switch Output Voltage (VOUT) 0V to VCC ±128 mA Input Rise and Fall Time (tr, tf) DC Input Diode Current @ (IIK) VIN < 0V DC Output (IOUT) Sink Current ±100 mA Control Input VCC = 2.3V to 3.6V 0 ns/V to 10 ns/V −65°C to +150°C Control Input VCC = 4.5V to 5.5V 0 ns/V to 5 ns/V DC VCC or Ground Current (ICC/IGND) Storage Temperature Range (TSTG) 1.65V to 5.5V Control Input Voltage (VIN) Junction Lead Temperature Switch I/O +150°C under Bias (TJ) 0 ns/V to DC −40°C to +85°C Operating Temperature (TA) Thermal Resistance (θJA) Junction Lead Temperature (TL) +260°C (Soldering, 10 Seconds) Power Dissipation (PD) @ +85°C SC70-5 150 mW MicroPak-6 200 mW SC70-5 425°C/Watt MicroPak-6 325°C/Watt 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 ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation. Note 2: The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed. Note 3: Unused inputs must be held HIGH or LOW. They may not float.
