CD74AC244E

Buffers, Drivers, Receivers, Transceivers Overview

The CD74AC244E is an octal buffer and line driver manufactured by Texas Instruments, belonging to the AC logic family. It features eight non-inverting channels with three-state outputs housed in a 20-pin PDIP package. The device operates within a supply voltage range of 2 V to 6 V. Key electrical specifications include a maximum low-level output current of 24 mA and a high-level output current of -24 mA. Propagation delay is typically 5 ns at 5 V with a 50 pF load. The component supports through-hole mounting and functions across a commercial temperature range of -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E' corresponds to the PDIP-20 package configuration as documented in official datasheets. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments, as these details are subject to change and require real-time verification from official supply chain sources.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with three-state control capabilities. Ensure the operating environment remains within the specified -40 °C to +85 °C temperature range. Verify that the system supply voltage aligns with the 2 V to 6 V operational window to maintain signal integrity and prevent device damage.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AC244 series of octal buffers and line drivers. It serves as a high-performance alternative to standard 74-series logic, offering faster switching speeds and wider voltage tolerance.
