Revised March 2002 FSAL200 Quad 2:1 Multiplexer/Demultiplexer Wide Bandwidth LAN Switch General Description Features The Fairchild Switch FSAL200 is a rail-to-rail quad 2:1 high-speed CMOS TTL-compatible multiplexer/demultiplexer LAN switch. The low On Resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise. ■ Typical 6Ω switch connection between two ports When OE is LOW, the select pin connects the A Port to the selected B Port output. When OE is HIGH, the switch is OPEN and a high-impedance state exists between the two ports. ■ Rail-to-rail signal handling ■ Minimal propagation delay through the switch ■ Low ICC ■ Zero bounce in flow-through mode ■ Control inputs compatible with TTL level ■ Low insertion loss ■ Route LAN Signals including: 10/100 Ethernet 10/1000 Ethernet 100VG-AnyLAN Token Ring 4/16 Mbps ATM25 SONET OCI 51.8 Mbps T1/E1 Ordering Code: Order Number Package Number FSAL200QSC MQA16 Package Description 16-Lead Quarter Size Outline Package (QSOP), JEDEC MO-137, 0.150" Wide Device also available in Tape and Reel.

The datasheet specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation outside datasheet specifications. Note 2: The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed. Note 3: Control input must be held HIGH or LOW, it must not float.

On Resistance is determined by the lower of the voltages on the two (A or B Ports). Note 5: ∆RON = RON max − RON min measured at identical VCC, temperature and voltage levels. Note 6: Flatness is defined as the difference between the maximum and minimum value of On Resistance over the specified range of conditions. www.fairchildsemi.com 2 Symbol tON tOFF Q OIRR Parameter VCC (V) TA = −40°C to +85°C Min D Units Conditions Turn On Time 4.5 − 5.5 10 20 ns VBn = 3V 3.0 - 3.6 28 40 ns VBn = 1.5V Turn Off Time 4.5 − 5.5 5 10 ns VBn = 3V S to Output 3.0 - 3.6 4 20 ns VBn = 1.5V Charge Injection 5.0 7 (Note 7) 3.3 3 Off Isolation Crosstalk pC −55 4.5 - 5.5 dB −75 3.0 - 3.6 BW Max S to Output (Note 8) Xtalk Typ dB −70 4.5 - 5.5 dB Figure Number Figures 1, 2 Figures 1, 2 CL = 0.1 nF, VGEN = 0V RGEN = 0 Ω RL = 100 Ω Figure 3 Figure 4 f = 30 MHz RL = 50 Ω Figure 4 f = 1 MHz RL = 100 Ω Figure 5 f = 30 MHz RL = 50 Ω 3.0 - 3.6 −75 dB 4.5 - 5.5 137 MHz RL = 100 Ω Figure 8 3.0 - 3.6 110 MHz RL = 50 Ω Figure 8 ∆RON/RL Distortion 4.5 - 5.5 2 (Note 7) 3.0 - 3.6 3 % RL = 100 Ω −3dB Bandwidth Figure 5 f = 1 MHz Note 7: Guaranteed by Design.
