EATURES: - - - - - - 5Ω bidirectional switches connect inputs to outputs Pin patibility with QS3245 250ps propagation delay Undershoot clamp diodes on all switch and control inputs LVTTL-patible control inputs Available in 40-pin QVSOP package DESCRIPTION: .. APPLICATIONS: - 3.3V to 2.5V Voltage translation - 2.5V to 1.8V Voltage translation - PCI bus isolation hot swap The QS32XV245 is a 16-bit high speed bus switch controlled by LVTTLpatible active low enable signal. When closed, the switches exhibit near zero propagation delay without generating additional ground bounce or switching noise. The QS32XV245 is specially designed for direct interface between 3.3V and 2.5V devices without any external ponents. 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 VCC is less than 5Ω typical, providing near zero propagation delay through the switch. Absence of DC path from switch I/O pins to VCC or ground makes QS32XV245 an ideal device for hot swapping applications. The QS32XV245 is characterized for operation from -40°C to +85°C.
