BCT4157EXT-TR

April, 2008, REV1.2 BCT4157/4157B Low-Voltage, 2.8Ω SPDT Analog Switch General Description Features The BCT4157/4157B is a high-bandwidth, fast single-pole double-throw (SPDT) CMOS switch. It can be used as an analog switch or as a low-delay bus switch. Specified over a wide operating power supply voltage range, 1.65V to 5.5V, the BCT4157/4157B has a maximum ON resistance of 5.1-ohms at 1.65V, 3.9-ohms at 2.3V & 2.85-ohms at 4.5V. ♦CMOS Technology for Bus and Analog Applications ♦ Low ON Resistance: 3-ohms @ 2.7V ♦ Wide VCC Range: 1.65V to 5.5V ♦ Rail-to-Rail Signal Range ♦ Control Input Overvoltage Tolerance: 5.5V min. ♦ High Off Isolation: 57dB at 10MHz ♦ 54dB (10MHz) Crosstalk Rejection Reduces Signal Distortion ♦ Break-Before-Make Switching ♦ High Bandwidth: 300 MHz ♦ Extended Industrial Temperature Range: –40°C to 85°C ♦ Improved Direct Replacement for NC7SB4157 ♦ Packaging (Pb-free & Green available): Break-before-make switching prevents both switches being enabled simultaneously. This eliminates signal disruption during switching. The control input, S, tolerates input drive signals up to 5.5V, independent of supply voltage. BCT4157/4157B is an improved direct replacement for the FSA4157/NC7SB4157 Pin Description Applications Name Cell Phones PDAs Portable Instrumentation Battery Powered Communications Computer Peripherals S Description Logic Control Vcc Positive Power Supply Connection Diagram(Top View) A Common Output/Data Port SC70-6 B0 Data Port (Normally Closed) GND B1 Ground Data Port Logic Function Table TDFN-6 S 1 6 B1 VCC 2 5 GND A 3 4 B0 Logic Input (S) Function 0 B0 Connected to A 1 B1 Connected to A ORDERING INFORMATION Ordering Code Package Description Temp Range Top Marking BCT4157EXT-TR 6-pin SC70 –40°C to +85°C ABG BCT4157BEXT-TR 6-pin TDFN 1.45X1 –40°C to +85°C ABG www.broadchip.com April, 2008, REV1.2 Low-Voltage, 2.8Ω SPDT Analog Switch ABSOLUTE MAXIMUM RATINGS (1) Supply Voltage VCC.........................................–0.5V to +7V DC Switch Voltage (VS) (2).…….......…..–0.5V to VCC +0.5V (2) DC Input Voltage (VIN) .…..…….....….......–0.5V to +7.0V DC VCC or Ground Current (ICC/IGND)..................±100mA DC Output Current (VOUT) .......................................128mA Storage Temperature Range (TSTG) ....... –65°C to +150°C Junction Temperature under Bias (TJ) .......…............ 150°C Junction Lead Temperature (TL) (Soldering, 10 seconds) .................................... 260°C Power Dissipation (PD) @ +85°C .............................180mW RECOMMENDED OPERATING CONDITIONS (3) Supply Voltage Operating (VCC)………………1.65V to 5.5V Control Input Voltage (VIN)………………………..0V to VCC Switch Input Voltage (VIN)…………………………0V to VCC Output Voltage (VOUT)…………………………….0V to VCC Operating Temperature (TA)………………...–40°C to +85°C Thermal Resistance (θJA)…………………………..350°C/W Note 1:Absolute Maximum Ratings” may cause permanent damage to the device.
