74ABT240N,602

Buffers, Drivers, Receivers, Transceivers Overview

The NXP USA Inc. 74ABT240N,602 is an octal inverting buffer with 3-State outputs manufactured using high-performance BiCMOS technology. It operates within a DC supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to +85°C. The device features two independent output enables (1OE, 2OE), each controlling four outputs. Key electrical parameters include a propagation delay of 3.1ns typical at 5V with 50pF load, input capacitance of 4pF, and output drive capability of +64mA/-32mA. Quiescent supply current is typically 50μA when outputs are disabled.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74ABT240 family includes multiple variants such as Plastic DIP, SO, SSOP, and TSSOP. Confirm that the component meets RoHS compliance standards if required for your manufacturing process. Ensure the temperature grade corresponds to your environmental specifications before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal inverting buffer with high-speed performance and strong drive strength is required. The BiCMOS technology offers low power dissipation compared to standard TTL while maintaining high speed. Consider the 3-State feature for bus sharing applications where multiple devices connect to a common line.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT series of high-speed BiCMOS logic devices produced by Philips Semiconductors, now NXP. The 74ABT240 specifically provides octal buffering with inversion. It is designed for applications requiring fast switching speeds and robust signal integrity in 5V logic environments.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements must maintain the 74ABT logic family, octal configuration, and 3-State output characteristics. Verify pin compatibility and electrical specifications match the original design requirements.
