74LVT16501ADGG,112

Universal Bus Functions Overview

The 74LVT16501ADGG,112 is an 18-bit universal bus transceiver manufactured by Nexperia (formerly NXP). It operates at a supply voltage of 2.7 V to 3.6 V and features non-inverting 3-state outputs in both send and receive directions. The device utilizes BiCMOS technology for high performance. Data flow is controlled by output enable, latch enable, and clock inputs. It supports live insertion and extraction without bus current loading when tied to a 5 V bus.

Universal Bus Functions Feature Summary

• Features active bus hold circuitry to maintain valid logic levels on unused or floating data inputs without external pull-up resistors.
• Supports live insertion and extraction operations while preventing bus current loading when the output is connected to a 5 V bus.
• Includes power-up reset functionality that ensures outputs enter a high-impedance state upon power application.

Universal Bus Functions Applications

• Bidirectional bus interface applications requiring 18-bit data transfer
• Systems supporting live insertion and hot-swapping operations
• Interfaces between 3.3 V logic systems and 5 V tolerant buses

Universal Bus Functions Procurement Notes

Verify the manufacturer designation as Nexperia due to the business transition from NXP Standard Products. Confirm the package type corresponds to TSSOP56 (SOT364-1) with a body width of 6.1 mm. Ensure compatibility with the -40 °C to +85 °C operating temperature range specified for this part variant.

Universal Bus Functions Selection Notes

Select this component for designs requiring 18-bit bidirectional data transmission with independent direction control. It is suitable for environments necessitating bus hold capabilities to simplify input handling. Consider the 3-state output capability and TTL switching levels for interfacing with various system voltages.

Universal Bus Functions Part Context

This device belongs to the 74LVT series of 3.3 V LVT 18-bit universal bus transceivers. It was originally produced by Philips Semiconductors and NXP before the standard product business became Nexperia. The ADGG suffix indicates the TSSOP56 plastic thin shrink small outline package version.

Universal Bus Functions Replacement Considerations

Public confirmed substitute part numbers include SN74LVTH16501DGGR, SN74LVTH16501DL, and SN74LVTH16501DLR from Texas Instruments.

Universal Bus Functions FAQ
