PI4ULS3V204 4-Bit Bi-directional Level Shifter for open-drain and Push-Pull Application Features Description V can be Less than, Greater than or Equal to The PI4ULS3V204 is a 4-bit configurable dual CCA V supply bidirectional auto sensing translator that does CCB 1.1V to 3.6V on A Port and 1.1V to 3.6V on B not require a directional control pin. The A and B ports Port are designed to track two different power supply rails, High-Speed with 24 Mb/s Data Rate for push-pull V and V respectively. Both the V and V CCA CCB CCA CCB application supply rails are configurable from 1.1V to 3.6V. This High-Speed with 2 Mb/s Data Rate for open-drain allows voltage logic signals on the V side to be CCA application translated into lower, higher or equal value voltage No Direction-Control Signal Needed logic signals on the V side, and vice-versa. CCB Low Bit-to-Bit Skew The translator has integrated 10 k pull-up Non-preferential Power-up Sequencing resistors on the I/O lines. The integrated pull-up ESD protection exceeds 8000V HBM per resistors are used to pull-up the I/O lines to either V CCA JESD22-A114 or V . The PI4ULS3V204 is an excellent match for CCB 2 Integrated 10 k Pull-up Resistors open-drain applications such as the I C communication Package: TSSOP-14,TQFN3.5x3.5-14,CSP-12 bus Applications 2 I C, SMBus, MDIO Low Voltage ASIC Level Translation Mobile Phones, PDAs, Camera Pin Configuration TQFN3.5x3.5-14(Top View) TSSOP-14(Top View) CSP-12(Bottom View) All trademarks are property of their respective owners. www.diodes.com 3/10/2017 2017-03-0002 PT0511-3 1 PI4ULS3V204 Block Diagram Figure 1: Block Diagram Maximum Ratings Note: o o Storage Temperature ................................................................................... -65 C to +150 C Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the DC Supply Voltage port B .............................................................................. -0.3V to +5.5V device.
