74ALVC16601MTDX

Overview

The onsemi 74ALVC16601MTDX is an 18-bit universal bus transceiver housed in a 56-lead Thin Shrink Small Outline Package (TSSOP). It integrates D-type latches and flip-flops to support transparent, latched, and clocked data flow modes. The device operates with a supply voltage range of 1.65V to 3.6V and features inputs and outputs tolerant up to 3.6V. Propagation delay ranges from 3.4 ns maximum at 3.0V–3.6V to 7.0 ns maximum at 1.65V–1.95V.

Feature Summary

• Combines D-type latches and flip-flops for versatile data handling across transparent, latched, and clocked modes.
• Supports live insertion and withdrawal through power-down high impedance states.
• Utilizes patented noise and EMI reduction circuitry for signal integrity.
• Provides robust electrostatic discharge protection exceeding 2000V via human body model testing.

Applications

• Low voltage bus architectures requiring bidirectional data transfer
• Systems supporting live insertion or hot-swapping capabilities
• High-speed digital interfaces utilizing 3.6V tolerant I/O levels

Procurement Notes

Verify the specific package variant, as this component is also available in a Fine-Pitch Ball Grid Array. Confirm that the ordering code includes the appropriate suffix if tape and reel packaging is required. Ensure compatibility with existing design constraints regarding the 56-lead TSSOP footprint and JEDEC MO-153 standards before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring 18-bit wide data paths with flexible control over data storage and transmission timing. It is suitable for applications needing 3.6V tolerance on both inputs and outputs while operating from lower supply voltages. Consider the propagation delay specifications relative to the target system clock frequency and operating voltage to ensure timing margins are met.

Part Context

This device belongs to the ALVC logic family, characterized by advanced CMOS technology designed for high-speed operation with low power dissipation. It serves as a bridge between different voltage domains within a system, allowing seamless communication between components operating at varying logic levels while maintaining signal integrity through specialized internal circuitry.

Replacement Considerations

Check for equivalent 18-bit universal bus transceivers with similar pinouts and electrical characteristics. Verify that any substitute supports the same 3.6V I/O tolerance and offers comparable propagation delays at the intended operating voltage. Ensure the replacement package matches the 56-lead TSSOP form factor for direct board integration.
