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.

PCA9509D,118 2. Features and benefits

 Bidirectional buffer isolates capacitance and allows 400 pF on port B of the device Voltage level translation from port A (1.35 V to VCC(B)  1.0 V) to port B (3.0 V to 5.5 V) Requires no external pull-up resistors on lower voltage port A Active HIGH repeater enable input Open-drain inputs/outputs Lock-up free operation Supports arbitration and clock stretching across the repeater Accommodates Standard-mode and Fast-mode I2C-bus devices and multiple masters

PCA9509D,118 1. General description

The PCA9509 is a level translating I2C-bus/SMBus repeater that enables processor lowvoltage 2-wire serial bus to interface with standard I2C-bus or SMBus I/O. While retainingall the operating modes and features of the I2C-bus system during the level shifts, it alsopermits extension of the I2C-bus by providing bidirectional buffering for both the data(SDA) and the clock (SCL) lines, thus enabling the I2C-bus or SMBus maximumcapacitance of 400 pF on the higher voltage side. Port A allows a voltage range from1.35 V to VCC(B)  1.0 V and requires no external pull-up resistors due to the internalcurrent source. Port B allows a voltage range from 3.0 V to 5.5 V and is overvoltagetolerant. Both port A and port B SDA and SCL pins are high-impedance when thePCA9509 is unpowered.For applications where Port A VCC(A) is less than 1.35 V or Port B VCC(B) is less than 3.0 V,use drop-in replacement PCA9509A.The bus port B drivers are compliant with SMBus I/O levels, while port A uses a currentsensing mechanism to detect the input or output LOW signal which prevents bus lock-up.Port A uses a 1 mA current source for pull-up and a 200  pull-down driver. This results ina LOW on the port A accommodating smaller voltage swings. The output pull-down on theport A internal buffer LOW is set for approximately 0.2 V, while the input threshold of theinternal buffer is set about 50 mV lower than that of the output voltage LOW. When theport A I/O is driven LOW internally, the LOW is not recognized as a LOW by the input.This prevents a lock-up condition from occurring. The output pull-down on the port Bdrives a hard LOW and the input level is set at 0.3 of SMBus or I2C-bus voltage levelwhich enables port B to connect to any other I2C-bus devices or buffer.The PCA9509 drivers are not enabled unless VCC(A) is above 0.8 V and VCC(B) is above2.5 V. The enable (EN) pin can also be used to turn on and turn off the drivers undersystem control. Caution should be observed to change only the state of the EN pin whenthe bus is idle.
