| IDTQS4A210 HIGH-PERFORMANCE CMOS TWO-CHANNEL SP4T MUX/DEMUX INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH(R) PRODUCTS HIGH-PERFORMANCE CMOS TWO CHANNEL SP4T MUX/DEMUX FEATURES: DESCRIPTION: IDTQS4A210 * * * * * * * * * * Low ON resistance: rDS(ON) = 5 Fast transition time: tTRAN = 6ns Wide bandwidth: 700MHz (-3dB point) Crosstalk: -110dB at 50KHz, -68dB at 5MHz, -66dB at 30MHz Off-isolation: -90dB at 50KHz, -60dB at 5MHz, -50dB at 30MHz Single 5V supply Can be used as multiplexer or demultiplexer TTL-compatible control inputs Ultra-low quiescent current: 3A Available in QSOP package APPLICATIONS: * * * * * * * * * High-speed video signal switching/routing HDTV-quality video signal multiplexing Audio signal switching/routing Data acquisition ATE systems Telecomm routing Switch between multiple video sources Token Ring transceivers High-speed networking The QS4A210 is a high-performance CMOS two-channel SP4T multiplexer/demultiplexer with individual enables. The low On-resistance of the QS4A210 allows inputs to be connected to outputs with low insertion loss and high bandwidth. TTL-compatible control circuitry with "Break-Before-Make" feature prevents contention. The QS4A210 with 700MHz bandwidth makes it ideal for high-performance video signal switching, audio signal switching, and telecom routing applications. Low power dissipation makes this device ideal for battery operated and remote instrumentation applications. The QS4A210 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, resulting in lower ground bounce The QS4A210 is characterized for operation at -40C to +85C.

Typ.(1) Max. Unit Dynamic Characteristics NOTES: 1. Typical values are at VCC = 5.0V, TA = 25C. 2. Max value is guaranteed but not production tested. 3. Measured by voltage drop between A and C pins or B and D pins at indicated current through the switch. ON resistance is determined by the lower of the voltages on the two (I, Y) 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.
