SN74LVCH244ADBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH244ADBR is an octal buffer and line driver manufactured by Texas Instruments, utilizing the LVCH logic series. It features eight non-inverting channels organized into two independent four-bit sections with separate output enable (OE) inputs. The device operates within a supply voltage range of 1.65 V to 3.6 V and utilizes a 20-pin SSOP package. Key electrical specifications include a maximum propagation delay of 6.7 ns at 2.7 V and 5.9 ns at 3.3 V. Output drive capabilities are rated at ±24 mA for both high and low states. The component supports mixed-mode signal operations across all ports and includes IOFF functionality to prevent back-driving during partial power-down conditions.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest documentation to ensure authenticity. Confirm that the ordering suffix matches the required tape-and-reel or tube packaging configuration for your assembly process. Cross-reference the RoHS compliance status with current environmental regulations applicable to your region before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing low-voltage digital systems requiring robust buffering for mixed-signal environments. The LVCH series is suitable for applications needing compatibility with both AC and DC coupled signals. Ensure the system voltage remains within the 1.65 V to 3.6 V range to maintain specified timing parameters and output drive strength.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74LVCH244A family of octal buffers. It serves as a standard solution for expanding I/O capabilities in low-power digital circuits. The device complements other logic families by offering specific advantages in mixed-mode signal handling and partial power-down protection, making it distinct from standard CMOS buffers lacking these features.
