NLASB3157 SPDT, 3 W RON Switch The NLASB3157 is an advanced CMOS analog switch fabricated with silicon gate CMOS technology. It achieves very low propagation delay and RDSON resistances while maintaining CMOS low power dissipation. Analog and digital voltages that may vary across the full power−supply range (from VCC to GND). This device is a drop in replacement for the NC7SB3157. The select pin has overvoltage protection that allows voltages above VCC, up to 7.0 V to be present on the pin without damage or disruption of operation of the part, regardless of the operating voltage. • • • • • • MARKING DIAGRAMS 6 Features • • • • • • • • • http://onsemi.com High Speed: tPD = 1.0 ns (Typ) at VCC = 5.0 V Low Power Dissipation: ICC = 2.0 mA (Max) at TA = 25°C Standard CMOS Logic Levels High Bandwidth, Improved Linearity Switches Standard NTSC/PAL Video, Audio, SPDIF and HDTV May be used for Clock Switching, Data Multiplexing, etc. RON Typical = 3 W @ VCC = 4.5 V Break Before Make Circuitry, Prevents Inadvertent Shorts 2 Devices can Switch Balanced Signal Pairs, e.g. LVDS u 200−Mb/s Latchup Performance Exceeds 300 mA Pin for Pin Drop in for NC7SB3157 Tiny SC88 and WDFN6 Packages ESD Performance: ♦ Human Body Model; u 2000 V; ♦ Machine Model; u 200 V Extended Automotive Temperature Range −55°C to +125°C (See Appendix) Pb−Free Packages are Available SC−88 DF SUFFIX CASE 419B AF MG G WDFN6 MT SUFFIX CASE 506AS FM G 1 AF, F = Specific Device Code M = Date Code* G = Pb−Free Package (Note: Microdot may be in either location) *Date Code orientation may vary depending upon manufacturing location.
