74ALVCR162601TX

Overview

The onsemi 74ALVCR162601 is an 18-bit universal bus transceiver featuring D-type latches and flip-flops for transparent, latched, and clocked data flow. It operates with a supply voltage of 1.65V to 3.6V and includes 3.6V tolerant I/Os. Integrated 26Ω series resistors reduce line noise. Propagation delay ranges from 4.3ns at 3.0V-3.6V to 9.2ns at 1.65V-1.95V. The device supports live insertion/withdrawal and utilizes patented noise reduction circuitry.

Feature Summary

• Combines D-type latches and flip-flops to enable transparent, latched, and clocked data modes controlled by dedicated enable and clock inputs.
• Incorporates 26Ω series resistors in both A and B port outputs to minimize line noise and electromagnetic interference.
• Supports live insertion and withdrawal operations through power-down high-impedance states and 3.6V tolerant inputs and outputs.

Applications

• Memory address drivers
• Clock drivers
• Bus transceivers and transmitters

Procurement Notes

Verify the specific package variant required, as the datasheet lists the TSSOP-56 (MTD56) configuration. Confirm that the ordering code matches the desired tape and reel suffix if applicable. Ensure compatibility with the 1.65V to 3.6V operating range and check for any end-of-life status updates from the manufacturer or distributor before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring 18-bit bidirectional data transfer with integrated noise suppression. The built-in 26Ω resistors eliminate the need for external components in high-speed applications. Consider the propagation delay specifications relative to the target supply voltage to ensure timing requirements are met within the -40°C to +85°C operating temperature range.

Part Context

This device belongs to the 74ALVC logic family, designed for low-voltage CMOS applications. It integrates latch and flip-flop functionality into a universal bus transceiver architecture. The inclusion of series resistors distinguishes it from standard transceivers by providing inherent signal integrity improvements for high-speed digital interfaces.
