74ALVCH162601DGGS

Overview

The Nexperia 74ALVCH162601DGGS 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, supporting low-power CMOS dissipation. The device includes bus hold inputs for signal integrity and utilizes the MULTIBYTE™ flow-through standard pin-out architecture. It supports partial power-down applications via IOFF circuitry to prevent backflow current. The component is specified for operation from -40 °C to +85 °C and complies with JEDEC standards JESD8-7, JESD8-5, and JESD8B/JESD36.

Feature Summary

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

Applications

• High-speed data bus interfacing
• Memory systems requiring controlled impedance
• Low-voltage logic translation between 1.65 V and 3.6 V domains

Procurement Notes

Verify the specific suffix 'DGGS' against official Nexperia documentation to confirm package type and tape/reel configuration. Ensure the procurement channel provides valid traceability for the SOT364-1 (TSSOP56) package. Confirm that the delivered units match the Rev. 3 product data sheet specifications regarding temperature range and electrical characteristics.

Selection Notes

Select this component when designing 18-bit wide buses requiring integrated termination to minimize external components. It is suitable for applications needing bidirectional data flow control with latch and clock enable capabilities. Consider the MULTIBYTE™ architecture for simplified PCB routing in high-density designs. Verify that the operating voltage aligns with the 1.65 V to 3.6 V range for optimal performance.

Part Context

This part belongs to the 74ALVCH family of advanced low-voltage CMOS hex bus transceivers. It extends the functionality of standard transceivers by incorporating internal termination resistors and bus hold features. The device is designed for high-speed applications where signal reflection and noise must be managed internally. It complements other logic families by providing robust interface solutions for mixed-voltage environments.

Replacement Considerations

Check for direct replacements within the 74ALVCH series that offer identical pinouts and functional parameters. Verify compatibility with existing board layouts due to the TSSOP56 package dimensions. Ensure any substitute maintains the 30 Ω termination resistor integration and IOFF capability.
