74LVCH16244ADGVJ

Overview

The Nexperia 74LVCH16244ADGVJ is a 16-bit buffer and line driver featuring 3-state outputs. It operates within a supply voltage range of 1.2 V to 3.6 V and supports inputs up to 5.5 V. The device includes four output enables (1OE, 2OE, 3OE, 4OE) controlling four outputs each. It utilizes TVSOP48 (SOT480-1) packaging with 48 leads. Static characteristics include an input leakage current of ±20 μA maximum at -40 °C to +125 °C. Dynamic propagation delay ranges from 1.0 ns to 11.3 ns depending on voltage.

Feature Summary

• Features bus hold circuitry on all data inputs to eliminate external pull-up resistors for unused lines.
• Includes IOFF circuitry that disables outputs to prevent damaging backflow current during partial power-down.
• Provides high-impedance state when the supply voltage is zero volts.

Applications

• Translating signals in mixed 3.3 V and 5 V logic environments
• Partial power-down applications requiring isolation
• Buffering 16-bit data buses

Procurement Notes

Verify the specific ordering suffix 'J' against official Nexperia documentation to confirm reel packaging specifications. Ensure the component matches the TVSOP48 package outline SOT480-1. Confirm temperature range compliance for -40 °C to +125 °C operation before finalizing procurement orders.

Selection Notes

Select this component when a 16-bit non-inverting buffer with 3-state control is required. The LVCH variant is appropriate for designs needing bus hold functionality on data inputs. Verify that the 5.5 V tolerant inputs meet system interface requirements for mixed-voltage logic levels.

Part Context

This part belongs to the 74LVC/LVCH family of 16-bit buffers. It shares functional similarities with the 74LVC16244A but includes specific bus hold features characteristic of the LVCH series. The device is designed for standard multibyte flow-through pin-out architectures.

Replacement Considerations

The 74LVC16244ADGV is a compatible alternative within the same package and electrical specification family.
