74ALVC162835ADGG,1

Overview

The Nexperia 74ALVC162835A is an 18-bit universal bus driver featuring registered outputs with integrated 30 Ω termination resistors and 3-state capability. It operates on a wide supply voltage range from 1.2 V to 3.6 V, supporting CMOS low-power consumption and direct TTL level interfacing. The device utilizes a MULTIBYTE flow-through standard pin-out architecture with low inductance multiple power and ground pins to minimize noise and ground bounce. It provides current drive of ±12 mA at 3.0 V and includes diode clamps on all inputs to accommodate strong drivers.

Feature Summary

• Integrated 30 Ω series termination resistors in both HIGH and LOW output stages for transmission line matching
• MULTIBYTE flow-through standard pin-out architecture enabling flexible data routing configurations
• Low inductance multiple VCC and GND pins designed to minimize noise and ground bounce effects
• Diode clamps on all inputs to accommodate strong drivers and protect against voltage spikes

Applications

• High-speed data buses requiring registered buffering and signal integrity management
• Systems utilizing 50 Ω transmission lines where integrated termination reduces external component count
• Mixed voltage environments requiring direct interface with TTL logic levels

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the application environment remains within the specified operating limits for voltage and temperature. Ensure proper handling procedures are followed due to the sensitivity of CMOS devices to electrostatic discharge during installation and storage.

Selection Notes

Select this component when an 18-bit registered driver with built-in termination is required for high-speed interfaces. Consider the TSSOP56 package constraints and the need for multiple ground connections to manage thermal and electrical performance. Evaluate the propagation delay specifications against the system clock requirements to ensure timing margins are met.

Part Context

This device belongs to the ALVC logic family, characterized by high speed and low power consumption. It serves as a registered buffer solution for complex digital systems. The integration of termination resistors distinguishes it from standard bus transceivers, offering a compact solution for maintaining signal quality in dense PCB layouts without additional discrete components.

Replacement Considerations

Check datasheets for other 18-bit registered drivers in the ALVC or LVC families. Verify compatibility regarding pin assignments, voltage ranges, and termination resistor values before substituting.
