SN74LVC244ADWG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC244ADWG4 is an octal buffer and line driver from Texas Instruments' LVC logic family. It features eight non-inverting channels with three-state outputs, designed for low-voltage CMOS applications operating between 1.65 V and 3.6 V. The device supports mixed-mode signal operation, allowing 5 V tolerant inputs while powered by lower voltages. Key electrical specifications include a maximum propagation delay of 6.7 ns at 2.7 V, output drive currents of ±24 mA, and a static current of 1 µA. It is housed in a 20-pin SOIC package and operates within a temperature range of -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides eight independent non-inverting buffer channels with three-state output control for efficient bus management.
• Supports mixed-mode signal operation, enabling compatibility between 5 V input signals and lower voltage power supplies.
• Includes Ioff functionality to prevent excessive current draw during hot-insertion or partial system power-down scenarios.

• Asynchronous data bus buffering and driving in embedded systems
• Signal level translation between different voltage domains
• Memory interface buffering in consumer electronics

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and tape/reel configuration. Confirm RoHS compliance status and lead times directly with authorized distributors, as these details are subject to change based on production schedules and regional availability requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-density buffering with low supply voltage constraints. The wide operating voltage range and 5 V tolerance make it suitable for interfacing legacy 5 V peripherals with modern low-voltage microcontrollers. Ensure thermal management aligns with the specified junction temperature limits for the intended application environment.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC244A series, representing Texas Instruments' Low-Voltage CMOS logic technology. The series is engineered for high-speed performance with reduced power consumption compared to older standards. The 'D' suffix indicates the SOIC-20 surface-mount package, while 'G4' typically denotes Green/RoHS-compliant manufacturing processes without halogenated flame retardants.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include the SN74LVC244ADW and SN74LVC244APWR. Verify pinout compatibility and electrical characteristics before substitution. Alternative packages such as TSSOP-20 may require PCB footprint adjustments despite functional equivalence.
