74AC11240NT

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AC11240NT is an octal buffer and line driver manufactured by Texas Instruments, utilizing the EPIC (Enhanced-Performance Implanted CMOS) process. It features symmetrical active-low output-enable inputs and provides inverting outputs with high fan-out capabilities. The device is organized as two independent 4-bit buffers, each with a separate OE input to control data flow from A inputs to Y outputs. Designed for 3-state memory address drivers, clock drivers, and bus-oriented receivers, it operates within a supply voltage range of 3 V to 5.5 V and supports an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type against project requirements, as the NT suffix denotes a standard plastic 300-mil DIP. Confirm that the logic family matches existing system designs, as AC series specifications differ from other variants like ACT or ABT. Ensure the design accommodates the required power dissipation limits for through-hole mounting. Cross-reference the latest datasheet revision to confirm parameter stability before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with inverting logic and 3-state outputs. The device is suitable for applications needing improved fan-in and fan-out characteristics compared to standard logic families. Consider the 300-mil DIP package if through-hole assembly is mandated. Verify that the 3 V to 5.5 V operating voltage aligns with the target system's power rails and signal levels.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74AC logic family, which is based on the EPIC CMOS process technology. The 74AC series is designed to offer higher speed and lower power consumption than earlier NMOS or standard CMOS counterparts. The octal configuration allows for efficient handling of wide data buses, making it a common choice for general-purpose digital logic applications requiring robust signal driving capabilities.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements include the SN74ACT11240 for 5V-only operation or the SN74LVC11240A for lower voltage applications. Verify that the replacement maintains the same inverting logic function and 3-state output behavior. Check if the alternative package options meet the mechanical constraints of the existing PCB footprint.
