74ALVC16240DTR

Buffers, Drivers, Receivers, Transceivers Overview

The onsemi 74ALVC16240DTR is a low-voltage 1.8/2.5/3.3 V 16-bit buffer with 3.6 V-tolerant inputs and outputs. It features inverting, 3-state outputs controlled by four independent Output Enable (OEn) pins for nibble control. Designed for high-speed operation, it achieves propagation delays of 3.0 ns max at 3.0–3.6 V, 3.7 ns max at 2.3–2.7 V, and 6.0 ns max at 1.65–1.95 V. The device supports live insertion and withdrawal, offers ±24 mA drive at 3.0 V, and includes IOFF specifications to guarantee high impedance when VCC = 0 V.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports live insertion and withdrawal capabilities

• Memory interface signal conditioning
• Portable electronic devices requiring low power consumption

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DTR' corresponds to the TSSOP-48 package and tape & reel shipping configuration. Confirm that the component meets the required RoHS compliance standards for your assembly process. Ensure that input pins are not left floating during operation to maintain stable logic levels and prevent excessive current draw.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring 16-bit parallel data buffering with independent control over data segments. The 3.6 V tolerance allows interfacing between different voltage domains without level shifters. Consider the propagation delay specifications relative to your system clock speed to ensure timing margins are met across the full operating temperature range.
