74LVT16500ADL,512

Universal Bus Functions Overview

The 74LVT16500ADL,512 is an 18-bit universal bus transceiver designed for VCC operation at 3.3 V. It features non-inverting 3-state bus-compatible outputs in both send and receive directions. Data flow is controlled by output enable (OEAB/OEBA), latch enable (LEAB/LEBA), and clock (CPAB/CPBA) inputs. The device supports transparent mode or latching based on control signals. Active bus-hold circuitry maintains unused inputs at valid logic levels without external pull-up resistors.

Universal Bus Functions Feature Summary

• Bidirectional data transfer with independent A-to-B and B-to-A control
• Integrated active bus-hold to secure floating inputs
• Supports live insertion and extraction operations
• Power-up reset and power-up 3-state initialization

Universal Bus Functions Applications

• High-speed bidirectional bus interfaces
• Memory bus architectures requiring 3-state buffering
• Systems utilizing mixed voltage domains up to 5 V
• Data acquisition systems with latchable input paths

Universal Bus Functions Procurement Notes

Verify the package designation matches the required footprint; the 'DL' suffix indicates a 56-lead SSOP package. Confirm that the operating temperature range of -40 °C to +85 °C aligns with the system environment. Ensure supply voltage stability within the 2.7 V to 3.6 V range to maintain specified electrical characteristics and timing parameters.

Universal Bus Functions Selection Notes

Select this component when an 18-bit wide bidirectional interface is required with simultaneous latching and driving capabilities. The negative edge-triggered clock inputs allow for specific timing synchronization. Consider the high drive capability and TTL compatibility if interfacing with legacy logic families. Verify that the 56-pin SSOP package fits the available PCB real estate constraints.

Universal Bus Functions Part Context

This device belongs to the LVT logic family, optimized for 3.3 V applications while maintaining compatibility with 5 V systems. It utilizes BiCMOS technology to achieve high performance with low power dissipation. The universal transceiver architecture combines register and buffer functions into a single integrated circuit, simplifying board design for complex data routing tasks.

Universal Bus Functions Replacement Considerations

The 74LVT16500ADGG is a functional equivalent offering identical specifications but housed in a TSSOP56 package instead of SSOP56. Both variants share the same electrical characteristics and pinout configuration, allowing for direct substitution if the mechanical package constraint permits.
