bidirectional HDMI switch. It is designed to
support HDMI/DVI television systems that
produce superior high-definition image quality.
The differential signal from the 2 HDMI ports is
multiplexed through the switch to form a single
output HDMI channel going to the HDMI receiver,
while the deselected output goes to the high-Z
(high impedance) state. It is designed for very low
cross-talk, low bit-to-bit skew, high channel-to-
channel noise isolation, and low I/O capacitance.
This switch offers very little high-speed signal
attenuation at the outputs, thus preserving the
signal integrity necessary to pass stringent

– 4KV for HDMI connector inputs
– 2KV for all other I/Os

Summary Description
1.1
Functional Description
The STHDMI001A routes physical layer signals for high bandwidth digital video and is
compatible with low voltage differential signaling standards like Transition Minimized
Differential Signaling (TMDS). The device multiplexes differential outputs from a video source
to one of the two corresponding outputs, then to a common display. The low ON resistance
(R ) and low I/O capacitance of the STHDMI001A result in a very small propagation delay.
ON
The device integrates SPDT-type switches for 3 differential data TMDS channels and 1
differential clock channel.

Maximum Rating
Stressing the device above the rating listed in the “Absolute Maximum Ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of this
specification is not implied. Exposure to Absolute Maximum Rating conditions for extended
periods may affect device reliability. Refer also to the STMicroelectronics SURE Program and
other relevant quality documents.
