74ALVCH162601DGG:1

Overview

The Nexperia 74ALVCH162601DGG is an 18-bit universal bus transceiver housed in a TSSOP56 package (SOT364-1). It operates within a supply voltage range of 1.65 V to 3.6 V and supports temperatures from -40 °C to +85 °C. The device features integrated 30 Ω termination resistors, bus hold inputs, and 3-state outputs. Data flow direction is controlled by OEAB/OEBA, LEAB/LEBA, CEAB/CEBA, and CPAB/CPBA inputs. Propagation delay ranges from 1.3 ns to 6.7 ns depending on the control signal and voltage.

Feature Summary

• Integrated 30 Ω termination resistors for signal integrity
• Bus hold functionality on data inputs
• MULTIBYTE™ flow-through standard pin-out architecture
• IOFF circuitry for partial power down applications

Applications

• High-speed parallel data buses
• Memory interface circuits
• Partial power down system designs

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the application environment remains within the specified temperature range of -40 °C to +85 °C. Ensure supply voltage does not exceed the maximum rating of 3.6 V. Check for compliance with relevant JEDEC standards based on the operating voltage. Validate IOFF requirements if partial power down functionality is utilized in the design.

Selection Notes

Select this component when an 18-bit wide bidirectional data path is required with integrated termination. The MULTIBYTE™ architecture simplifies PCB routing compared to discrete solutions. Consider the ALVCH family characteristics for low power consumption and direct TTL level interfacing capabilities. Evaluate the propagation delay specifications against the target system clock speeds to ensure timing margins are met.

Part Context

This device belongs to the ALVCH logic family, designed for advanced low-voltage CMOS applications. It utilizes BiCMOS technology to achieve high speed while maintaining low power dissipation. The 74ALVCH162601 provides a standardized solution for wide data buses, integrating functions typically requiring external components into a single 56-lead package.

Replacement Considerations

Check for 74ALVCH162601 variants with different suffixes for package or tape/reel options. Verify functional compatibility with other 18-bit universal bus transceivers if redesigning.
