SN74ALVC16835DLR

Universal Bus Functions Overview

The SN74ALVC16835DLR is an 18-bit universal bus driver designed for 1.65V to 3.6V VCC operation. It features a 56-pin SSOP package and provides bidirectional data flow control between ports A and Y. The device supports 24mA high-level and low-level output currents with 3-state outputs, enabling efficient signal buffering and bus driving in low-voltage applications.

Universal Bus Functions Feature Summary

• Universal bus driver architecture supporting bidirectional data transfer
• Operates within a wide voltage range of 1.65V to 3.6V
• Provides robust 24mA drive capability for both logic high and low states
• Utilizes 3-state outputs to prevent bus contention

Universal Bus Functions Applications

• Signal buffering in low-voltage digital systems
• Bus driving for 18-bit data interfaces
• Memory and storage controller interconnects
• Portable electronic devices requiring low power operation

Universal Bus Functions Procurement Notes

Verify the specific suffix 'DLR' indicates tape and reel packaging, distinct from tube variants like 'DL'. Confirm current production status as some listings indicate end-of-life or obsolescence timelines. Ensure compatibility with 1.65V-3.6V supply rails before integration. Check for alternative packages if pin count constraints exist.

Universal Bus Functions Selection Notes

Select this component when an 18-bit wide bus interface is required at sub-3.3V logic levels. The ALVC series offers faster switching than standard LVC families while maintaining low power consumption. Ensure input voltages do not exceed the VCC + 0.5V limit to avoid latch-up. Verify that the 56-SSOP package fits the PCB footprint requirements.

Universal Bus Functions Part Context

This part belongs to Texas Instruments' 74ALVC family, which combines advanced CMOS technology with low voltage operation. It serves as a direct replacement for older 18-bit bus transceivers in modern portable electronics. The device is optimized for high-density board layouts where space and power efficiency are critical design parameters.

Universal Bus Functions Replacement Considerations

Check for SN74ALVC16835DGGR (TSSOP package) if surface mount profile differs. Verify SN74ACT16823DLR only if 5V operation is acceptable, noting it is a different logic family. No direct pin-compatible 3.3V-only alternatives exist without verifying voltage tolerance.
