PI74HSTL1212AEX

Translators, Level Shifters Overview

The PI74HSTL1212 is a 24-bit bidirectional level-shifting transceiver designed for translation between 1.8V HSTL and LVCMOS/LVTTL domains. It features two independent 12-bit slices with separate supply rails: VCCA at 1.8V and VCCB at 3.3V. The device supports asynchronous communications and includes dual direction control inputs (1DAB/1DBA and 2DAB/2DBA) for flexible data flow management. Operating temperatures range from -40°C to +85°C, and it is available in a 64-pin TSSOP package.

Translators, Level Shifters Feature Summary

• Supports 1.8V HSTL Class I Buffer translation
• Dual independent 12-bit slice direction control
• Bi-directional non-inverting tranceivers with separate supply rails

Translators, Level Shifters Applications

• Asynchronous communications between HSTL and LVTTL/LVCMOS data buses
• Translation between 1.8V HSTL and LVCMOS logic levels

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging type, such as tape and reel options indicated by an 'X' suffix. Confirm RoHS compliance status and green material specifications directly from the datasheet or official product change notices before procurement.

Translators, Level Shifters Selection Notes

Select this component when interfacing 1.8V HSTL memory interfaces with 3.3V LVTTL or LVCMOS systems. Ensure the design accommodates the required 12-bit slice granularity and utilizes the dedicated direction control pins for managing bidirectional data paths effectively.

Translators, Level Shifters Part Context

This device belongs to the Pericom Semiconductor line of level shifters, now often associated with Diodes Incorporated distribution channels. It serves as a specialized interface solution for mixed-voltage digital systems requiring robust signal translation between different logic families.

Translators, Level Shifters Replacement Considerations

Check for updated part numbers within the same family that may include Pb-free and Green packaging suffixes (e.g., EA variants). Verify pin compatibility and electrical characteristics if substituting with other 24-bit bi-directional transceivers.
