PI74STX4G4245ZJEX

Translators, Level Shifters Overview

The PI74STX4G4245ZJE is a 4-bit noninverting buffer/transceiver featuring configurable dual supply voltage operation. It integrates two separate supply rails: Port A (VCCA) operates from 1.65V to 3.6V, while Port B (VCCB) operates from 2.3V to 5.5V, with the constraint that VCCA must be less than or equal to VCCB. The device provides one unidirectional buffer channel and one bidirectional transceiver channel controlled by an xDIR pin supplied by VCCB. It supports industrial operating temperatures ranging from -40°C to +85°C and utilizes a 16-pin TDFN package.

Translators, Level Shifters Feature Summary

• Configurable dual supply voltage architecture supporting translation between low-voltage logic levels on Port A and higher voltage levels on Port B.
• Integrated direction control for the bidirectional data channel allows flexible signal routing between ports via the xDIR pin.
• Power-down high-impedance state ensures inputs and outputs remain inactive during low-power modes.

Translators, Level Shifters Applications

• Voltage level shifting between 1.8V/3.3V systems and 5V systems
• Bidirectional data buffering in mixed-voltage digital circuits
• Unidirectional signal transmission in embedded interfaces

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging configuration. The 'E' suffix indicates Pb-free and Green material compliance, while the 'X' suffix denotes tape and reel packaging. Confirm the exact part number matches the required package type and environmental specifications before procurement.

Translators, Level Shifters Selection Notes

Select this component when interfacing circuits requiring both unidirectional buffering and bidirectional translation within a single package. Ensure the system design respects the VCCA ≤ VCCB voltage constraint. Verify that the required output drive current aligns with the specified ±12mA at 3V or ±24mA at 5V capabilities.

Translators, Level Shifters Part Context

This device belongs to the STX series of level shifters designed for advanced package solutions. It combines buffer and transceiver functionalities into a compact form factor, addressing space-constrained applications requiring mixed-signal voltage translation without utilizing multiple discrete components.
