74ALVCH162601DGGY

Overview

The Nexperia 74ALVCH162601DGGY is an 18-bit universal bus transceiver featuring integrated 30 Ω termination resistors and 3-state outputs. It operates within a supply voltage range of 1.65 V to 3.6 V. The device supports data flow control via output enable, latch enable, clock enable, and clock inputs. It includes bus hold on data inputs and IOFF circuitry for partial power-down applications. The component is specified for operation from -40 °C to +85 °C.

Feature Summary

• Universal transceiver architecture with integrated 30 Ω termination resistors
• Configurable data flow using latch, clock, and output enable controls
• Bus hold functionality on all data inputs
• IOFF circuitry prevents backflow current during partial power-down

Applications

• High-speed parallel bus interfaces
• Memory systems requiring controlled data latching
• Mixed-signal environments utilizing low-voltage CMOS logic

Procurement Notes

Verify the specific ordering suffix DGGY corresponds to the TSSOP56 package (SOT364-1) and the -40 °C to +85 °C temperature range. Confirm that the 'Y' suffix aligns with the required reel or cut tape packaging format. Ensure the procurement request matches the exact part number to avoid receiving variants with different pinouts or electrical characteristics.

Selection Notes

Select this component when an 18-bit wide interface is required alongside built-in signal integrity termination. The inclusion of latch and clock enables allows for precise timing control in complex data paths. Verify that the system voltage falls within the 1.65 V to 3.6 V operating range and that the thermal environment remains within the specified industrial temperature limits.

Part Context

This device belongs to the ALVCH logic family, designed for low-voltage high-speed applications. It utilizes CMOS technology to achieve low power dissipation while maintaining fast switching speeds. The MULTIBYTE™ architecture ensures standard pin-out compatibility for easy integration into existing board layouts.

Replacement Considerations

Direct replacements must match the 18-bit width, TSSOP56 package, and integrated 30 Ω termination. Verify functional equivalence regarding latch and clock control signals.
