Texas Instruments Inc. (TI) has announced the addition of two new Specialty Switches to its TS family of signal switches, the TS5V330 and the TS3V330. These are Quad Single-Pole Double-Throw (SPDT) video switches. The TS5V330 supports an operating range from 4.5V to 5.5V, while the TS3V330 is a lower-voltage component, operational from 3V to 3.6V.

Leveraging its extensive expertise and knowledge in digital switch design and advanced process technology, TI is targeting the devices at high frequency video applications, such as multiplexing/demultiplexing video signals on VGA cards. Both devices are also fully specified for partial-power-down applications (using Ioff).

Specified for composite and RGB video applications, the TS5V330 and the TS3V330 offer low differential gain and phase shift. The TS5V330 has a differential gain (DG) of 0.64 percent, and a typical phase shift (DP) of 0.1 degree (typical). The TS3V330 has a gain (DG) of 0.82 percent, and 0.1 degree typical phase shift.

The company touts wide bandwidth (300MHz minimum) coupled with low ON-State Resistance (3-ohm Ron typical for the TS5V330 and 5-ohm Ron typical for the TS3V330). Even with multiple video signals, crosstalk (XTALK) for the TS5V330 is rated at -63dB and -80dB typical for the TS3V330.

Both the TS5V330 and the TS3V330 are currently available to sample. The TS5V330 and the TS3V330 are offered in the space saving 16-pin QFN (RGY) package along with the SSOP (DBQ), and TSSOP (PW) packaging. Budgetary pricing for both the TS5V330 is set at $1.12 in quantities of 1,000 and TS3V330 is set at $1.36 in quantities of 1,000.
