The QS3VH16212 has very low ON resistance, resulting in under 250ps propagation delay through the switch. The device operates as a 24-bit bus switch or a 12-bit bus exchanger, which provides data exchanging between the four signal ports through the data-select (S0 - S2) terminals. In the OFF and ON states, the switches are 5V-tolerant. In the OFF state, the switches offer very high impedence at the terminals. The combination of near-zero propagation delay, high OFF impedance, and over-voltage tolerance makes the QS3VH16212 ideal for high performance communications applications. The QS3VH16212 is characterized for operation from -40°C to +85°C. APPLICATIONS: • • • • • Hot-swapping 10/100 Base-T, Ethernet LAN switch Low distortion analog switch Replaces mechanical relay ATM 25/155 switching FUNCTIONAL BLOCK DIAGRAM 1 of 12 Channels 1A1 1B1 1A2 1B2 Flow Control S0 S1 S2 The IDT logo is a registered trademark of Integrated Device Technology, Inc.

This parameter is guaranteed but not production tested. 3. The bus switch contributes no propagation delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 0.2ns at CL = 50pF. Since this time constant is much smaller than the rise and fall times of typical driving signals, it adds very little propagation delay to the system. Propagation 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. 4.
