IDTQS3V245 3.3V HIGH SPEED BUS SWITCH INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH® PRODUCTS 3.3V HIGH SPEED BUS SWITCH IDTQS3V245 FEATURES: 5 Ω bi-directional switches connect inputs to outputs Pin compatibility with QS3245 250ps propagation delay Undershoot Clamp Diodes on all switch and control Inputs LVTTL-compatible control Inputs Available in SOIC and QSOP packages DESCRIPTION: APPLICA TIONS: 3.3V to 2.5V voltage translation 2.5V to 1.8V voltage translation PCI bus isolation hot swap The QS3V245 is an 8-bit high speed bus switch controlled by LVTTLcompatible active low enable signal. When closed, the switches exhibit near zero propagation delay without generating additional ground bounce or switching noise. The QS3V245 is specially designed for direct interface between 3.3V and 2.5V devices without any external components. When operating from a 3.3V supply, the logic high level at the switch output is clamped to 2.5V when the switch input signal exceeds 2.5V. This device can be used for switching 2.5V buses without signal attenuation. The ON resistance at 3.3V V is less than CC 5Ω typical, providing near zero propagation delay through the switch. CC Absence of DC path from switch I/O pins to V or ground makes QS3V245 an ideal device for hot swapping applications. The QS3V245 is characterized for operation from -40 °C to +85°C.
