SN74LVCH244APWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH244APWR is an octal buffer and line driver from the Texas Instruments LVCH logic series. It features eight non-inverting channels with three-state outputs, organized as two independent four-bit sections. The device operates within a supply voltage range of 1.65 V to 3.6 V. Key electrical specifications include a maximum high-level output current of -24 mA and a low-level output current of 24 mA. Propagation delay is specified at 3.1 ns or 2.8 ns depending on conditions. It functions in temperatures from -40°C to +85°C and is housed in a 20-pin TSSOP package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode signal operations across all ports for flexible interface compatibility
• Provides IOFF functionality to enable partial power-down mode and back-drive protection
• Accepts input voltages up to 5.5 V, allowing safe translation from higher voltage logic levels

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous data bus communication between different logic domains
• Memory and memory mapping applications requiring level shifting
• Signal buffering for high-speed digital systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-20 package and tape-and-reel shipping configuration. Confirm RoHS compliance status and manufacturing origin through official Texas Instruments documentation or authorized distributor certificates before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 1.65 V to 3.6 V operation with robust 5.5 V tolerant inputs. It is suitable for applications needing three-state control for bus sharing. Ensure the required propagation delay and drive current meet system timing constraints compared to standard LVC alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCH244A family of CMOS octal buffers. It is designed for low-voltage applications where interface flexibility with 5 V devices is necessary. The LVCH series offers improved performance over standard LVC devices while maintaining compatibility with existing 3.3 V and 2.5 V system architectures.
