What is the Surface Mount ?

having leads that are designed to be soldered on the side of a circuit board that the body of the component is mounted on.

What is the Operating Temperature ?

The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

What is the Packaging ?

Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.

What is the Part Status ?

Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.

What is the Terminal Form ?

Occurring at or forming the end of a series, succession, or the like; closing; concluding.

What is the Terminal Pitch ?

The center distance from one pole to the next.

What is the Max Supply Voltage ?

In general, the absolute maximum common-mode voltage is VEE-0.3V and VCC+0.3V, but for products without a protection element at the VCC side, voltages up to the absolute maximum rated supply voltage (i.e. VEE+36V) can be supplied, regardless of supply voltage.

What is the Min Supply Voltage ?

The minimum supply voltage (V min ) is explored for sequential logic circuits by statistically simulating the impact of within-die process variations and gate-dielectric soft breakdown on data retention and hold time.

What is the Nominal Supply Current ?

Nominal current is the same as the rated current. It is the current drawn by the motor while delivering rated mechanical output at its shaft.

What is the Quiescent Current ?

The quiescent current is defined as the current level in the amplifier when it is producing an output of zero.

What is the Synchronous Rectifier ?

Synchronous rectification is a technique for improving the efficiency of rectification by replacing diodes with actively controlled switches, usually power MOSFETs or power bipolar junction transistors (BJT).

What is the RoHS Status ?

RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.

SCC68681E1A44,529 DESCRIPTION

The Philips Semiconductors SCC68681 Dual UniversalAsynchronous Receiver/Transmitter (DUART) is a single-chipMOS-LSI communications device that provides two independentfull-duplex asynchronous receiver/transmitter channels in a singlepackage. It is compatible with other S68000 family devices, and canalso interface easily with other microprocessors. The DUART can beused in polled or interrupt driven systems. It is manufactured in aCMOS process.The operating mode and data format of each channel can beprogrammed independently. Additionally, each receiver andtransmitter can select its operating speed as one of eighteen fixedbaud rates, a 16× clock derived from a programmable counter/timer,or an external 1× or 16× clock. The baud rate generator andcounter/timer can operate directly from a crystal or from externalclock inputs. The ability to independently program the operatingspeed of the receiver and transmitter make the DUART particularlyattractive for dual-speed channel applications such as clusteredterminal systems.Each receiver is quadruply buffered to minimize the potential ofreceiver overrun or to reduce interrupt overhead in interrupt drivensystems. In addition, a flow control capability is provided to disable aremote DUART transmitter when the buffer of the receiving device isfull.Also provided on the SCC68681 are a multipurpose 6-bit input portand a multipurpose 8-bit output port. These can be used as generalpurpose I/O ports or can be assigned specific functions (such asclock inputs or status/interrupt outputs) under program control.
