Revised January 2001 NC7SZ66 TinyLogic Low Voltage UHS Single SPST Normally Open Analog Switch or 1-Bit Bus Switch General Description Features The NC7SZ66 is a ultra high-speed (UHS) CMOS compatible single-pole/single-throw (SPST) analog switch or 1-bit bus switch. The LOW on resistance of the switch allows inputs to be connected to outputs 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. ■ Space saving SOT23 or SC70 5-lead package ■ Broad VCC Operating Range 1.65V–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 CMOS input levels ■ >250 MHz −3dB bandwidth Ordering Code: Order Package Product Code Number Number Top Mark NC7SZ66M5 MA05B 7Z66 5-Lead SOT23, JEDEC MO-178, 1.6mm NC7SZ66M5X MA05B 7Z66 5-Lead SOT23, JEDEC MO-178, 1.6mm 3k Units on Tape and Reel NC7SZ66P5 MAA05A Z66 5-Lead SC70, EIAJ SC-88a, 1.25mm Wide 250 Units on Tape and Reel NC7SZ66P5X MAA05A Z66 5-Lead SC70, EIAJ SC-88a, 1.25mm Wide 3k Units on Tape and Reel Package Description Logic Symbol Supplied As 250 Units on Tape and Reel Analog Symbol Pin Descriptions Pin Names Description OE Switch Enable Input A Bus A I/O B Bus B I/O Connection Diagram Function Table OE B0 Function L HIGH-Z State Disconnect H A0 Connect (Top View) TinyLogic is a trademark of Fairchild Semiconductor Corporation. © 2001 Fairchild Semiconductor Corporation DS012177 www.fairchildsemi.com NC7SZ66 TinyLogic Low Voltage UHS Single SPST Normally Open Analog Switch or 1-Bit Bus Switch November 1996 NC7SZ66 Absolute Maximum Ratings(Note 1) Recommended Operating Conditions (Note 3) −0.5V to +7.0V Supply Voltage (VCC) DC Switch Voltage (VS) DC Input Voltage (VIN) (Note 2) −0.5V to VCC +0.5V Power Supply Operating (VCC) −0.5V to +7.0V 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 DC VCC /GND Current (ICC /IGND) Control Input; VCC = 2.3V−3.6V Control Input; VCC = 4.5−5.5V Storage Temperature Range −65°C to +150°C (TSTG) 1.65V to 5.5V Control Input Voltage (VIN) 0 ns/V to 5 ns Switch I/O Junction Lead Temperature 0 ns/V to DC −40°C to +85°C Operating Temperature (TA) +150°C under Bias (TJ) Thermal Resistance (θJA) Junction Lead Temperature (TL) +260°C (Soldering, 10 Seconds) Power Dissipation (PD) @ +85°C SOT23-5 200 mW SC70-5 150 mW 0 ns/V to 10 ns SOT23-5 300°C/Watt SC70-5 425°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.
