74ACT11240DWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ACT11240DWR is an octal buffer and line driver manufactured by Texas Instruments, belonging to the ACT logic series. It features eight independent inputs and outputs with inverting polarity and three-state output capability. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a maximum high-level output current of -24 mA and a low-level output current of 24 mA. Static current is specified at 8 µA, while operating supply current reaches 80 µA. Propagation delay is typically 8.9 ns at 5 V with a 50 pF load. It functions reliably across an industrial temperature range from -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DWR' corresponds to the SOIC-24 package and tape-and-reel packaging configuration. Confirm that the ACT logic family specifications align with the target system's voltage and speed requirements. Ensure compliance with RoHS directives if required by the application environment. Cross-reference the manufacturer part number against authorized distributor catalogs to validate authenticity and current production status.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when eight isolated buffered channels are required with active pull-up and pull-down capabilities. The ACT series offers faster switching speeds compared to standard LS or HC families. Consider the inverting nature of the logic function during schematic design. The wide output drive current supports direct interfacing with heavy capacitive loads or long transmission lines without additional buffering stages.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the logic polarity of the SN74ACT11240DWR?

The device features inverting polarity, meaning each output is the logical complement of its corresponding input.

Does the SN74ACT11240DWR support bidirectional data flow?

No, it is a unidirectional buffer. Bidirectional functionality requires devices with separate direction control pins, such as the 74ACT245.

What is the maximum operating supply voltage?

The maximum recommended supply voltage (VCC) is 5.5 V.
