GTL16612DL,512

Universal Bus Functions Overview

The GTL16612DL,512 is an 18-bit bidirectional universal translator designed for VCC operation at 3.3 V with I/O compatibility up to 5 V. It translates between GTL/GTL+ logic levels on B ports and LVTTL/TTL logic levels on A ports. The device features non-inverting 3-State bus compatible outputs in both send and receive directions. Data flow is controlled by output enable, latch enable, and clock inputs. It includes power-up reset, power-up 3-State, positive edge triggered clock inputs, and latch-up protection exceeding 500 mA per JESD78.

Universal Bus Functions Feature Summary

• Translates between GTL/GTL+ logic levels (B ports) and LVTTL/TTL logic levels (A ports)
• Features 5 V I/O tolerant A ports with no bus current loading when tied to a 5 V bus
• Provides 3-State buffers with specific output drive capabilities on both sides
• Includes power-up reset, power-up 3-State, and positive edge triggered clock inputs

Universal Bus Functions Applications

• Bidirectional bus interface translation

Universal Bus Functions Procurement Notes

Verify the component status as the source datasheet indicates Philips Semiconductors origin. Confirm the package type matches the required 56-Pin Plastic SSOP or TSSOP configuration. Ensure the operating temperature range of -40 to +85 °C aligns with system requirements. Check for any specific ordering suffixes that may affect packaging or specifications.

Universal Bus Functions Selection Notes

Select this component for applications requiring high-performance BiCMOS translation between 3.3 V GTL/GTL+ and 5 V LVTTL/TTL systems. Consider the 18-bit width for wide bus interfaces. Evaluate the propagation delay characteristics against system timing constraints. Verify ESD protection levels meet environmental standards.

Universal Bus Functions Part Context

This part belongs to the GTL16612 family of universal translators. It is designed for use in systems where different logic families need to communicate efficiently. The device supports both GTL and GTL+ standards, providing flexibility in termination voltage requirements.

Universal Bus Functions Replacement Considerations

Check for direct pin-to-pin replacements within the same family. Verify electrical characteristics such as propagation delay and output drive strength match the original design requirements. Ensure the replacement part supports the same voltage levels and package types.

Universal Bus Functions FAQ

What is the function of the VREF pin?

The VREF pin provides the reference voltage for the GTL/GTL+ side (B ports) to ensure proper logic level detection.

How is data flow controlled in the GTL16612?

Data flow is controlled by output enable (OEAB/OEBA), latch enable (LEAB/LEBA), and clock (CPAB/CPBA) inputs for each direction.
