74LVCH16541ADGG,51

Overview

The Nexperia 74LVCH16541ADGG is a 16-bit buffer and line driver featuring three-state outputs controlled by dedicated enable inputs. It operates within a supply voltage range of 1.2 V to 3.6 V, supporting CMOS low-power consumption. The device incorporates bus hold circuitry on all data inputs to eliminate the need for external pull-up resistors. It provides high-impedance outputs when powered down and ensures compatibility with mixed 3.3 V and 5 V logic environments.

Feature Summary

• Features five-volt tolerant inputs and outputs for direct interfacing with 5 V logic systems.
• Includes bus hold functionality on data inputs to maintain stable states without external components.
• Maintains high-impedance output states during power-off conditions to prevent backflow currents.

Applications

• Mixed 3.3 V and 5 V system interconnects
• Bus-oriented transmissions
• Clock distribution and buffering

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and temperature rating. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and adherence to current JEDEC standards.

Selection Notes

Select this component for designs requiring wide supply voltage flexibility between 1.2 V and 3.6 V. The integrated bus hold feature simplifies PCB layout by removing the requirement for external pull-up resistors on unused or floating input lines.

Part Context

This device belongs to the LVCH logic family, designed for low-voltage CMOS applications. It utilizes a standard multibyte flow-through pin-out architecture, facilitating easy integration into existing digital circuit topologies that require parallel data buffering.

Replacement Considerations

Consult official Nexperia substitution guides for verified equivalents. Cross-referencing requires matching the TSSOP48 package (SOT362-1) and ensuring identical electrical characteristics for the target application environment.

FAQ

How does the device handle unused inputs?

All data inputs are equipped with bus hold circuits, which automatically hold the input at a defined logic level, eliminating the need for external pull-up or pull-down resistors.

What is the behavior of the outputs when VCC is 0 V?

When VCC is 0 V, the outputs assume a high-impedance OFF-state, preventing damaging backflow currents through the device in partial power-down scenarios.
