Frequently Asked Questions
What logic family does the SN74AHCT240DW belong to, and what voltage levels does it support?
The SN74AHCT240DW belongs to the AHCT (Advanced High-speed CMOS TTL-compatible) logic family. It accepts 3.3V or 5V TTL-compatible inputs and operates with a supply voltage of 4.5V to 5.5V, making it ideal for interfacing between 3.3V and 5V logic systems.
What is the output drive capability of the SN74AHCT240DW?
The SN74AHCT240DW provides a typical output drive current of 24mA (IOL) in the low state and -24mA (IOH) in the high state. This strong drive capability allows it to directly drive bus lines, LEDs, or other moderate-load devices without additional buffering.
What package does the SN74AHCT240DW come in, and are there pin-compatible alternatives?
The SN74AHCT240DW comes in a 20-pin wide SOIC (DW) package. Pin-compatible alternatives include the SN74AHCT240DBR (SSOP) and SN74AHCT240PW (TSSOP). Logic-compatible substitutes from other manufacturers include the 74AHCT240 from NXP or ON Semiconductor.
What are the typical applications of the SN74AHCT240DW?
The SN74AHCT240DW is commonly used for bus buffering, line driving, address buffering in memory systems, signal isolation between voltage domains, and output port expansion in microcontroller and FPGA designs. Its inverting octal structure also suits clock tree buffering and glue logic in industrial control and communication equipment.
