74LVC244ADB,112

Overview

The Nexperia 74LVC244ADB,112 is an octal buffer and line driver featuring 3-state outputs. It operates within a supply voltage range of 1.2 V to 3.6 V. The device includes two output enables (1OE and 2OE), each controlling four outputs. Inputs are overvoltage tolerant up to 5.5 V. Propagation delay ranges from 1.0 ns to 15.8 ns depending on voltage. Output drive capability reaches ±24 mA. Operating temperature spans -40 °C to +125 °C.

Feature Summary

• Provides 3-state outputs controlled by separate enable inputs for bus management
• Features Schmitt-trigger action at all inputs for noise tolerance
• Includes IOFF circuitry to prevent backflow current during partial power-down
• Accepts direct interface with TTL levels and supports mixed 3.3 V and 5 V environments

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffering
• Transceivers and bidirectional bus protocols

Procurement Notes

Verify the specific ordering suffix 'ADB' against official Nexperia documentation to confirm package type and availability status. Confirm RoHS compliance and REACH status directly with the manufacturer or authorized distributor before procurement. Ensure the component matches the required operating temperature range and electrical specifications for the target application.

Selection Notes
