IDTQS3VH16862
DESCRIPTION:
The QS3VH16862 HotSwitch with 20-bit dual port is a high bandwidth
bus switch. The QS3VH16862 has very low ON resistance, resulting in
under 250ps propagation delay through the switch. The switches are
controlled by independent active low enable (BEx) LVTTL compatible
control inputs. In the ON state, the switches can pass signals up to 5V. 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 QS3VH16862 ideal for high perfor-
mance communications applications.
The QS3VH16862 is characterized for operation from -40°C to +85°C.

NOTES:
1. See Test Conditions under TEST CIRCUITS AND WAVEFORMS.
2. 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 C
L
= 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. Minimums are guaranteed but not production tested.
白光LED光衰原因之荧光粉性能的衰退 到目前，白光 LED、尤其是小功率白光 LED 的发光性能快速衰退已越来越为人们所认识。其实，盲目地夸大宣传，只能将 LED 行业引向歧途，不正视白光 LED 存在的问题，只能延缓白光 LED 应用的发展。只有正视问题、研究问题、尽早解决问题，白光 LED 才能健康、快速发展。 白光 LED 当前面临的一个主要问题就寿命问题。由于白光 LED 的价格尚很...[详细]
