PI6ULS5V9617A Level Translating Fast-Mode Plus I2C-bus/SMbus Repeater Features Description 2 channel, bidirectional buffer isolates capacitance The PI6ULS5V9617A is a CMOS integrated circuit 2 intended for Fast-mode Plus (Fm+) I C-bus or SMBus and allows 540pF on either side of the device at 1 applications. It can provide level shifting between low MHz and up to 4000 pF at lower speeds voltage (down to 0.6V) and higher voltage (2.2V to 5.5V) Voltage level translation from 0.6V to 5.5V and in mixed-mode applications. from 2.2V to 5.5V The PI6ULS5V9617A enables the system designer Footprint and functional replacement for to isolate two halves of a bus for both voltage and PI6ULS5V9617A at Fast-mode speeds 2 capacitance, accommodating more I C devices or longer Port A operating supply voltage range of 0.6V to 2 trace length. It also permits extension of the I C-bus by 5.5V with normal levels(0.4V + 0.8V V ) CC(A) CC(B) providing bidirectional buffering for both the data (SDA) Port B operating supply voltage range of 2.2V to and the clock (SCL) lines, thus enabling two buses of 5.5V with static offset level 540 pF at 1 MHz or up to 4000 pF at lower speeds. The 2 5V tolerant I C-bus and enable pins SDA and SCL pins are overvoltage tolerant and are high-impedance when the PI6ULS5V9617A is 0 Hz to 1 MHz clock frequency (the maximum unpowered. system operating frequency may be less than 1MHz The 2.2V to 5.5V bus port B drivers have the static because of the delays added by the repeater) level offset, while the adjustable voltage bus port A Active HIGH repeater enable input referenced to drivers eliminate the static offset voltage. This results in V CC(B) a LOW on the port B translating into a nearly 0V LOW Open-drain input/outputs on the port A which accommodates the smaller voltage Latching free operation swings of lower voltage logic. The EN pin is referenced Supports arbitration and clock stretching across the to V and can also be used to turn the drivers on and CC(B) repeater off under system control. Accommodates Standard-mode, Fast-mode and 2 Fast-mode Plus I C-bus devices, SMBus (standard Pin Configuration and high power mode), PMBus and multiple masters 2 Powered-off high-impedance I C-bus pins ESD protection exceeds 8000V HBM per JESD22- A114 Package: MSOP-8L, SOIC-8L and TDFN2x3-8L MSOP-8L, SOIC-8L(Top View) Pin Description Pin Name Description V port A supply voltage (0.6V to 5.5V) CC(A) SCLA serial clock port A bus SDAA serial data port A bus GND supply ground (0 V) EN active HIGH repeater enable input SDAB serial data port B bus TDFN2*3-8L(Top View) SCLB serial clock port B bus V port B supply voltage (2.2V to 5.5V) CC(B) All trademarks are property of their respective owners. www.diodes.com 1/18/2017 2016-11-0003 PT0482-4 1 PI6ULS5V9617A 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 RATINGS may cause permanent damage to the Supply Voltage port B ...................................................................................... -0.5V to +6.0V device.
