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 Flow Control S0 S1 S2 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
