GTLP2T152K8X

Overview

The GTLP2T152K8X is a 2-bit LVTTL/GTLP transceiver manufactured by onsemi in an 8-VFSOP package. It provides bidirectional signal level translation between LVTTL and GTLP logic levels, controlled by a single T/R pin. The device operates within a supply voltage range of 3.15V to 3.45V and supports an operating temperature range of -40°C to 85°C. It features non-inverting data polarity and tri-state outputs. The A port handles LVTTL signals with output currents of ±24mA, while the B port manages GTLP signals with a sink current capability of +50mA.

Feature Summary

• Bidirectional interface supporting LVTTL-to-GTLP signal level translation
• Integrated edge rate control circuitry to minimize bus-settling time and reduce output noise
• External VREF pin allows for adjustable receiver threshold optimization
• PVT compensation circuitry ensures consistent performance across process, voltage, and temperature variations

Applications

• High-speed backplane interconnects requiring GTLP signaling
• System boards connecting LVTTL processors to GTLP peripherals
• Live insertion applications utilizing power-off high-impedance states

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package marking matches the US8 designation. Check datasheet revisions for any updates to electrical characteristics or mechanical dimensions. Ensure environmental compliance documentation aligns with project requirements. Validate that the specific ordering suffix corresponds to the required tape and reel configuration.

Selection Notes

Select this component when interfacing LVTTL logic with GTLP buses. Consider the US8 package for space-constrained surface mount designs. Evaluate the need for external pull-up resistors if unused inputs are present, though the device offers bus-hold capabilities. Verify that the system VTT and VREF supplies meet the specified tolerance ranges for optimal noise margins.

Part Context

This part belongs to the GTLP2T152 family of 2-bit transceivers. It is functionally equivalent to other variants like the GTLP2T152MX but differs in packaging. The device utilizes Fairchild's advanced BiCMOS technology. It serves as a bridge between different logic families in mixed-voltage systems.
