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.

SN74ALS621A-1DWR description

These octal bus transceivers are designed for asynchronous two-way communication between data buses. Thecontrol-function implementation allows for maximum flexibility in timing.These devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, dependingupon the logic levels at the output-enable (OEAB and OEBA) inputs.The output-enable inputs disable the device so that the buses are effectively isolated. The dual-enableconfiguration gives the transceivers the capability to store data by simultaneously enabling OEAB and OEBA.Each output reinforces its input in this transceiver configuration. When both OEAB and OEBA are enabled andall other data sources to the two sets of bus lines are in the high-impedance state, both sets of bus lines (16 total)remain at their last states. The 8-bit codes appearing on the two sets of buses are identical for theSN74ALS621A, SN74ALS623A, and SN74AS623 or complementary for the SN74ALS620A.The -1 versions of the SN74ALS620A and SN74ALS621A are identical to the standard versions, except thatthe recommended maximum IOL is increased to 48 mA in the -1 versions.The SN74ALS620A, SN74ALS621A, SN74ALS623A, and SN74AS623 are characterized for operation from0°C to 70°C.
