PI4ULS3V08ZFE

Translators, Level Shifters Overview

The PI4ULS3V08ZFE is an 8-bit universal bidirectional level shifter with automatic direction control, designed for low voltage operation from 1.2V to 3.6V on both VCCA and VCCB supply rails. It supports bus speeds up to 180 Mbps for push-pull applications and provides a drive capability of 12mA. The device features independent translation of each bit, ensuring flexible voltage translation between asynchronous data buses without explicit direction control signals. It includes ESD protection exceeding JESD22 standards (2000V HBM) and latch-up performance exceeding 100mA per JESD 78. Operating temperature range is -40°C to +85°C.

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'ZF' corresponds to lead-free and green packaging in the manufacturer's official documentation. Confirm that the 'E' suffix indicates Pb-free status as defined in the datasheet notes. Ensure the package code matches the 36-pin TQFN 5x6 specification. Cross-reference the part number against current Diodes Incorporated or Pericom product lists to confirm availability status and any potential obsolescence notices.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring asynchronous communication between data buses operating at different voltage levels within the 1.2V to 3.6V range. It is suitable for applications needing high-speed data transfer up to 180 Mbps with minimal external control logic due to its automatic direction detection. Consider the 36-contact TQFN package constraints and the requirement to tie unused inputs to VCCI or GND for proper operation.

Translators, Level Shifters Part Context

The PI4ULS3V08 belongs to the PI4ULS3V series of universal bidirectional level shifters manufactured by Diodes Incorporated (formerly Pericom Semiconductor). This series is engineered for low-voltage digital interfaces, providing robust signal translation capabilities. The ZFE variant specifically denotes the lead-free, green packaging option housed in a 36-pin TQFN footprint, aligning with environmental compliance standards while maintaining the electrical characteristics of the base PI4ULS3V08 device.
