74LVC16240ADGG,118

Overview

The Nexperia 74LVC16240ADGG,118 is a 16-bit inverting 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 driven by 3.3 V or 5 V devices. The device includes four output enables (1OE, 2OE, 3OE, 4OE) controlling four outputs each. It incorporates IOFF circuitry for partial power-down applications to prevent backflow current. The component is housed in a TSSOP48 package (SOT362-1) and complies with JEDEC standards.

Feature Summary

• Features 5 V tolerant inputs and outputs for interfacing with 5 V logic systems.
• Includes IOFF circuitry that disables outputs to prevent damaging backflow current during partial power-down.
• Utilizes low inductance multiple power and ground pins to minimize noise and ground bounce.
• Provides direct interface capability with TTL levels.

Applications

• Mixed 3.3 V and 5 V application environments
• Partial power-down system configurations
• High-speed data bus buffering
