DESCRIPTION:
The QS3VH16212 Bus Exchange HotSwitch with 24-bits is a high
bandwidth bus switch. 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 perfor-
mance 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
