This device provides a set of four high-speed CMOS switches connecting inputs to outputs. The low ON resistance of the QS4A101 allows inputs to be connected to outputs with low insertion loss and high bandwidth. The QS4A101, with 1.4GHz bandwidth, is ideal for high-performance video signal switching, audio signal switching, and telecomm routing applications. Low power dissipation makes this device ideal for battery operated and remote instrumentation applications. The QS4A101 is offered in the QSOP package which has several advantages over conventional packages such as PDIP and SOIC, including: • Reduced signal delays due to denser component packaging on circuit boards • Reduced system noise due to less pin inductance APPLICATIONS: • • • • • • • IDTQS4A101 High-speed video signal switching/routing Audio signal switching/routing Data acquisition ATE systems Telecomm routing Token Ring transceivers High-speed networking The QS4A101 is characterized for operation at -40°C to +85°C.

Typical values are at VCC = 5.0V, TA = 25°C. 2. Max value is guaranteed but not production tested. 3. Measured by voltage drop between A and C pins at indicated current through the switch ON resistance is determined by the lower of the voltages on the two (A, B) pins. 4. The bus switch contributes no group delay other than the RC delay of the ON resistance of the switch and load capacitance. Group delay of the bus switch, when used in a system, is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side. 3 IDTQS4A101 HIGH-PERFORMANCE CMOS ANALOG FOUR-CHANNEL SPST SWITCH INDUSTRIAL TEMPERATURE RANGE TYPICAL CHARACTERISTICS 60 180 VCC = 5V RL = 75Ω 150 50 120 40 Crosstalk (dB) (dB ) V CC = 5V R L = 75 Ω 90 30 Crosstalk Off-isolation 60 20 30 10 0 1K 10K 100K 1M 10M 100M 1G Off-isolation 0 100M 10G 200M Freq uen cy (H z) Off-isolation and Crosstalk vs. Frequency 300M 400M 500M Frequency (Hz) 600M 700M Off-isolation and Crosstalk vs. Frequency NOTES: 1.
