74ALVCH16601DGG:11

Overview

The Nexperia 74ALVCH16601DGG:11 is an 18-bit universal bus transceiver with 3-state outputs and bus hold inputs. It operates within a supply voltage range of 1.65 V to 3.6 V, supporting CMOS low power dissipation. The device features MULTIBYTE™ flow-through standard pin-out architecture and includes I_OFF circuitry for partial power-down applications. It provides current drive capability of ±24 mA at 3.0 V and supports direct interface with TTL levels.

Feature Summary

• Supports bidirectional data flow controlled by dedicated enable, latch, and clock inputs for both A-to-B and B-to-A directions.
• Includes bus hold functionality on data inputs to maintain stable logic states.
• Features I_OFF circuitry that disables outputs to prevent damaging backflow currents during partial power-down conditions.

Applications

• High-density memory buffer applications
• Clock drivers and bus-oriented transfers
• Control signal routing in multi-byte systems

Procurement Notes

Verify the specific ordering suffix ':11' against official Nexperia documentation to confirm reel size or tape-and-reel specifications. Ensure the TSSOP56 package variant matches the required board layout dimensions. Confirm compliance with JEDEC standards relevant to the target operating voltage range before finalizing procurement.

Selection Notes

Select this component for designs requiring 18-bit wide data transfer with independent direction control. The MULTIBYTE™ architecture simplifies PCB layout compared to discrete solutions. Ensure the system voltage falls within the 1.65 V to 3.6 V range and consider the ±24 mA drive capability for transmission line termination requirements.

Part Context

This device belongs to the ALVCH series of high-speed CMOS logic components manufactured by Nexperia. It utilizes advanced technology to achieve low power consumption while maintaining high performance. The 74ALVCH16601 is designed for applications demanding reliable data transfer across wide buses with minimal noise sensitivity.

Replacement Considerations

Check for compatible 18-bit bus transceivers from the same family if pin compatibility is required. Verify that alternative parts support the same 3-state output configuration and bus hold features. Ensure replacement devices meet the same voltage and temperature specifications.
