South Portland, Maine " Fairchild Semiconductor International announces the FSAT66, last spring, a low-voltage, Single Pole/Single Throw (SPST) analog switch that utilizes TTL-level control circuitry. It is a precursor of other Fairchild announcements. The TTL-level input allows designers to route higher voltage signals using lower voltage control levels. The Normally Open (NO) FSAT66's MicroPak package (1.45mm2) is perhaps the smallest form factor with this function on the market today, and ideal for use in mobile phones, digital cameras, PDAs, disk drives and other handheld electronics.
For handheld electronics, the FSAT66 will serve as an analog switch with a 5V VCC and CMOS logic levels that need 3.75V on the select pin to change states. Alternatively, an analog switch with TTL logic levels requires only 2.0V to change states. The lower TTL logic level allows the switch to be controlled by ASICs or microprocessors of 3.0V or lower. The FSAT66 SPST analog switch provides designers with a simple, high-performance solution for combining technologies in devices with mixed voltage levels, the company believes.
One feature of the FSAT66 is its preservation of signal integrity. With a low ON resistance (RON) of 5 Ohms, signal attenuation is reduced. With a low charge injection of 0.05pC, there is less noise induced by the control circuitry. The FSAT66 offers minimal Total Harmonic Distortion (THD) of 0.011% that is ideal for audio applications. The FSAT66 device is available in two packaging configurations"5-lead SC70 (model FSAT66P5X, 3000-piece tape-and-reel) and 6-lead chipscale MicroPak (model FSAT66L6X, 5000-piece tape-and-reel).
The FSAT66 adds to Fairchild's portfolio of products targeted at portable applications. These products include audio amplifiers, LEDs for backlighting, supervisory products such as temperature sensors and reset generator circuits, and DC/DC conversion products such as DC/DC converters, LDOs and MOSFETs.
