74ALVC16601MTD

Overview

The 74ALVC16601MTD is an 18-bit universal bus transceiver combining D-type latches and flip-flops for transparent, latched, and clocked data flow. It operates on a 1.65V to 3.6V supply with 3.6V tolerant I/Os. Propagation delay ranges from 3.4 ns max at 3.0V–3.6V to 7.0 ns max at 1.65V–1.95V. The device features power-down high-impedance states, supports live insertion, and utilizes patented noise/EMI reduction circuitry. It is housed in a 56-lead TSSOP package.

Feature Summary

• Combines D-type latches and flip-flops to enable transparent, latched, and clocked data modes
• Supports live insertion and withdrawal via power-down high-impedance inputs and outputs
• Incorporates patented noise and EMI reduction circuitry for signal integrity

Applications

• Low voltage bus interfacing requiring 3.6V tolerance
• Systems supporting live insertion or hot-swapping
• High-speed data transmission with EMI sensitivity

Procurement Notes

Verify the specific ordering code suffix against manufacturer documentation to confirm package type and reel configuration. Ensure compatibility with the required supply voltage range of 1.65V to 3.6V. Confirm that unused inputs are properly terminated to maintain high-impedance states during power transitions as specified in the datasheet notes.

Selection Notes

Select this component for applications requiring bidirectional 18-bit data transfer with flexible control modes. The 3.6V tolerant I/O capability allows interfacing between lower voltage logic and 3.6V systems. Consider the propagation delay specifications relative to the operating voltage to ensure timing requirements are met within the -40°C to +85°C temperature range.

Part Context

This device belongs to the ALVC series of low-voltage CMOS logic components. It is manufactured by Fairchild Semiconductor (now part of onsemi). The MTD suffix indicates the 56-lead Thin Shrink Small Outline Package (TSSOP) variant, distinct from the FBGA option available for the same logical function.

Replacement Considerations

Check for equivalent 18-bit bus transceivers with compatible VCC ranges and pinouts. Verify that any substitute maintains the 3.6V I/O tolerance and similar propagation delays. Ensure the replacement package matches the physical footprint if board space is constrained.
