74ALVT16543DGG,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ALVT16543DGG,118 is a high-performance BiCMOS registered transceiver designed for VCC operation at 2.5 V or 3.3 V with I/O compatibility up to 5 V. It functions as two 8-bit transceivers or one 16-bit transceiver containing D-type latches with separate control pins. The device features 3-State buffers, TTL input/output switching levels, and active bus-hold data inputs. Key electrical parameters include propagation delays of 1.6 ns (typical) at 3.3 V and 1.8 ns at 2.5 V. Output capabilities reach +64 mA/-32 mA. It operates within a temperature range of -40 °C to +85 °C and is housed in a 56-pin TSSOP package.

• Supports live insertion and extraction while maintaining power-up 3-State outputs
• Includes active bus-hold circuitry to eliminate external pull-up resistors for unused inputs
• Provides latch-up protection exceeding 500mA per JEDEC Std 17 standards
• Features ESD protection exceeding 2000 V per MIL STD 883 Method 3015

Buffers, Drivers, Receivers, Transceivers Applications

• Universal bus interface applications requiring 16-bit data transfer
• Systems interfacing between 2.5 V/3.3 V logic and 5 V I/O environments
• Registered transceiver circuits utilizing D-type latching functionality

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the component manufacturer status, as the original NXP Standard Product business transitioned to Nexperia in February 2017. Ensure datasheet references align with current branding guidelines. Confirm the specific ordering suffix matches the required 56-pin TSSOP Type II package configuration. Cross-reference the type number against official Nexperia documentation to validate specifications and availability.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit registered data transmission with mixed voltage domains. It is suitable for applications needing 5 V tolerant I/Os driven by lower voltage supplies. Consider the 56-pin TSSOP footprint for space-constrained PCB layouts. Evaluate the need for bus-hold inputs to simplify design by removing external pull-up components.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the ALVT logic family, characterized by high-speed performance and low voltage operation. It serves as a registered transceiver variant within the broader 74-series logic ecosystem. The technology utilizes BiCMOS processes to achieve fast propagation delays while maintaining compatibility with standard TTL logic levels across different supply voltages.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Consult official Nexperia documentation for verified substitute part numbers. Ensure any replacement maintains the 56-pin TSSOP package and supports the required 2.5 V/3.3 V operating ranges. Verify that alternative devices offer equivalent 5 V I/O tolerance and registered transceiver functionality.
