DATASHEET
WIDE BANDWIDTH VIDEO SIGNAL SWITCH, 5 PORT
General Description
Features
The IDTVS512 is a bi-directional 5-Port 2:1
multiplexer/demultiplexer with Hi-Z outputs for both RGB
and composite video switching applications. With the
additional two ports, vertical and horizontal synchronous
signals can be switched in addition to switching the RGB
and composite signals between different components
(DVDs, VCRs, PCs, etc.). The VideoSwitch can be driven
from a current output RAMDAC or voltage output composite
video source.

Low on-resistance, low crosstalk, low OFF isolation and
wide bandwidth features make it ideal for video and other
applications. The IDTVS512 offers a high-performance
(600 MHz), low-cost solution to switch between video
sources.

1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 3.3V,TA = 25°C ambient and maximum loading.
3. Measured by the voltage drop between Y and I pins at indicated current through the switch. On-Resistance is determined by the
lower of the voltages on the two (Y &I) pins.
4. This parameter is determined by device characterization but is not production tested.

Description
1. For max. or min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device
type.
2. Guaranteed by design.,
3. The bus switch contributes no propagational 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 0.25ns for 10pF load. Since this time constant
is much smaller than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational 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 interactions with the load on the driven side.

Applications Information
Logic Inputs
The logic control inputs can be driven up to +3.6V regardless of the supply voltage. For example, given a +3.3V supply, the
output enables or select pins may be driven low to 0V and high to 3.6V. Driving IN Rail-to-RailÆ minimizes power
consumption.
Power-supply Sequencing
Proper power-supply sequencing is advised for all CMOS devices. It is recommended to always apply VCC before applying
signals to the input/output or control pins.

1 CL = Load capacitance: includes jig and probe capacitance.
2 RT = Termination resistance: should be equal to ZOUT of the Pulse Generator.
3 Waveform 1 is for an output with internal conditions such that the output is low
except when disabled by the output control. Waveform 2 is for an output with
internal conditions such that the output is high except when disabled by the
output control.
4 All input impulses are supplied by generators having the following
characteristics: PRR ≤ MHz, Zo = 50Ω, tR ≤ 2.5ns, tF ≤ 2.5ns.
5 The outputs are measured one at a time with one transition per measurement.
