The IDTQS3V245 is an 8-bit high speed bus switch controlled by LVTTL-compatible active low enable signal. When closed, the switches exhibit near zero propagation delay without generating additional ground bounce or switching noise.
The IDTQS3V245 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 VCC is less than 5 typical, providing near zero propagation delay through the switch.Absence of DC path from switch I/O pins to VCC or ground makes QS3V245 an ideal device for hot swapping applications.
The IDTQS3V245 is characterized for operation from -40°C to +85°C.
