74LVT16500ADGG,118

Universal Bus Functions Overview

The 74LVT16500ADGG,118 is an 18-bit universal bus transceiver manufactured by Nexperia. It features non-inverting 3-state outputs and operates at a supply voltage of 2.7 V to 3.6 V. The device supports bidirectional data flow controlled by output enable (OEAB/OEBA), latch enable (LEAB/LEBA), and clock (CPAB/CPBA) inputs. It utilizes BiCMOS technology with TTL-compatible input and output switching levels. The package is TSSOP56 (SOT364-1). Propagation delays range from 0.5 ns to 6.4 ns depending on the signal path and voltage conditions.

Universal Bus Functions Feature Summary

• Provides 18-bit bidirectional bus interface capability with 3-state buffers for both send and receive directions.
• Incorporates active bus-hold circuitry to maintain unused or floating data inputs at valid logic levels without external pull-up resistors.
• Supports live insertion and extraction while ensuring power-up reset and power-up 3-state functionality.
• Offers interface compatibility with systems operating at 5 V supply despite 3.3 V operation.

Universal Bus Functions Applications

• High-performance bi-directional bus interfaces in computing systems
• Memory mapping applications requiring transparent and latched modes
• Systems permitting live insertion and extraction of bus components

Universal Bus Functions Procurement Notes

Verify the manufacturer designation as Nexperia B.V., noting the transition from NXP Standard Product business. Confirm the specific ordering suffix ',118' corresponds to the TSSOP56 plastic thin shrink small outline package (SOT364-1). Ensure compliance with RoHS directives and check for any product discontinuation notices or lifecycle status updates prior to final procurement decisions.

Universal Bus Functions Selection Notes

Select this component for designs requiring 18-bit wide data paths with independent direction control. The negative edge-triggered clock inputs and separate latch enables allow flexible data storage and display operations. Consider the 3.3 V operating range and 5 V tolerance when interfacing with mixed-voltage buses. The TSSOP56 package is suitable for surface mount applications requiring high pin density.

Universal Bus Functions Part Context

This device belongs to the 74LVT series of low-voltage CMOS logic products. It functions as a universal transceiver, combining buffer and flip-flop/latch capabilities in a single package. The 'A' suffix typically denotes enhanced specifications or revisions within the LVT family. The part is designed for automotive, industrial, computing, consumer, and wearable application markets.

Universal Bus Functions Replacement Considerations

Check for direct pin-to-pin replacements within the 74LVT16500 family. Verify if alternative packages such as SSOP56 (74LVT16500ADL) are available if footprint changes are permissible. Cross-reference with other 18-bit universal transceivers from the same manufacturer to ensure functional equivalence regarding control signals and electrical characteristics.
