PI6ULS5V9517A Level Translating I2C Bus/SMBus Repeater Features Description The PI6ULS5V9517A is a CMOS integrated circuit intended 2 channel, bidirectional buffer 2 for I2C-bus or SMBus applications. It can provide level I C-bus and SMBus compatible shifting between low voltage (down to 0.8 V) and higher Port A operating supply voltage range of 0.8 V to 5.5 V voltage (2.2V to 5.5V) in mixed-mode applications. And it Port B operating supply voltage range of 2.2 V to 5.5 V enables I2C and similar bus system to be extended, without Voltage level translation from 0.8 V to 5.5 V and from 2.2 degeradation of peformance even during level shifting. V to 5.5 V The PI6ULS5V9517A enables the system designer to isolate Active HIGH repeater enable input two halves of a bus for both voltage and capacitance, Open-drain input/outputs accommodating more I2C devices or longer trace length. It Lock-up free operation also permits extension of the I2C-bus by providing Supports arbitration and clock stretching across the bidirectional buffering for both the data (SDA) and the clock repeater 2 Accommodates Standard-mode and Fast-mode I C-bus (SCL) lines, thus allowing two buses of 400 pF to be connected devices and multiple masters in an I2C application. 2 Powered-off high-impedance I C-bus pins 2 5.5 V tolerant I C-bus and enable pins Pin Description 0 Hz to 400 kHz clock frequency (the maximum system operating frequency may be less than 400 kHz because of Pin No. the delays added by the repeater) MSOP-8 DFN UQFN Name Description ESD protection exceeds 8KV HBM per JESD22-A114 SOIC-8 2x3-8 1.6x1.6-8 Package: MSOP-8L, SOIC-8L and DFN2x3- port A supply voltage 1 7 1 V 8L,UQFN1.6x1.6-8L CC(A) (0.8 to 5.5 V) 2 8 2 SCLA serial clock port A bus 3 1 3 SDAA serial data port A bus 4 2 4 GND supply ground (0 V) active HIGH repeater 5 3 5 EN enable input 6 4 6 SDAB serial data port B bus 7 5 7 SCLB serial clock port B bus port B supply voltage 8 6 8 V CC(B) (2.2 to 5.5 V) Pin Configuration MSOP-8 and SOIC-8 UQFN1.6x1.6-8L(Top view) DFN2x3-8L(Top view) PI6ULS5V9517A www.diodes.com December 2017 Document Number DS40195 Rev 1-2 Diodes Incorporated 1 PI6ULS5V9517A Block Diagram EN Function SCLA = SCLB H SDAA = SDAB L disabled Figure 1: Block Diagram Maximum Ratings Note: o o Storage Temperature ...................................................................................... -55 C to +125 C Stresses greater than those listed under MAXIMUM Supply Voltage port B ........................................................................................ -0.5V to +6.0V RATINGS may cause permanent damage to the Supply Voltage port A ......................................................................................... -0.5V to+6.0V device.
