SN74LVCH244ADWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH244ADWR is an octal buffer and line driver from Texas Instruments, belonging to the LVCH logic series. It features eight non-inverting channels with three-state outputs, designed for low-voltage CMOS applications operating between 1.65V and 3.6V. The device provides high drive capability with output currents of ±24mA at 3.3V. It supports mixed-mode signal operation, allowing 5V tolerant inputs while powered by lower voltages. Packaged in a 20-pin SOIC (DW) format, it ensures reliable performance across industrial temperature ranges.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DWR' corresponds to the SOIC-20 package and tape-and-reel shipping configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments, as these details are subject to change based on manufacturing availability and regional supply chain conditions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 3.3V operation with 5V input compatibility. Ensure the application demands the specific propagation delay characteristics of the LVCH series compared to standard LVC or AHC families. Verify that the thermal requirements of the SOIC-20 package align with the system's power dissipation limits under maximum load conditions.
