IDTQS3VH16244 INDUSTRIAL TEMPERATURE RANGE 2.5V / 3.3V 16-BIT HIGH BANDWIDTH BUS SWITCH QUICKSWITCH PRODUCTS IDTQS3VH16244 2.5V / 3.3V 16-BIT HIGH BANDWIDTH BUS SWITCH FEATURES: DESCRIPTION: N channel FET switches with no parasitic diode to Vcc The QS3VH16244 HotSwitch is a 16-bit high band bus switch. The Isolation under power-off conditions QS3VH16244 has very low ON resistance, resulting in under 250ps propa- No DC path to Vcc or GND gation delay through the switch. The switches can be turned ON under the 5V tolerant in OFF and ON state control of the LVTTL-compatible xG signal for bidirectional data flow with no 5V tolerant I/Os added delay or ground bounce. In the OFF and ON states, the switches are Low RON - 4 typical 5V-tolerant. In the OFF state, the switches offer very high impedance at the Flat RON characteristics over operating range terminals. Rail-to-rail switching 0 - 5V The combination of near-zero propagation delay, high OFF impedance, and Bidirectional dataflow with near-zero delay: no added ground over-voltage tolerance makes the QS3VH16244 ideal for high performance bounce communications applications. Excellent RON matching between channels The QS3VH16244 is characterized for operation from -40C to +85C. Vcc operation: 2.3V to 3.6V High bandwidth - up to 500 MHz LVTTL-compatible control Inputs Undershoot Clamp Diodes on all switch and control Inputs Low I/O capacitance, 4pF typical Available in TSSOP package APPLICATIONS: Hot-swapping 10/100 Base-T, Ethernet LAN switch Low distortion analog switch Replaces mechanical relay ATM 25/155 switching FUNCTIONAL BLOCK DIAGRAM 1G 2G 1A1 1Y1 2Y1 2A1 1A2 2A2 1Y2 2Y2 1A3 1Y3 2A3 2Y3 1A4 1Y4 2A4 2Y4 3G 4G 3Y1 3A1 4Y1 4A1 3A2 3Y2 4A2 4Y2 3A3 3Y3 4A3 4Y3 3A4 3Y4 4A4 4Y4 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
