{"product_id":"mc74act240mr1","title":"MC74ACT240MR1","description":"\u003cp\u003eThe MC74ACT240MR1 is an octal inverting buffer\/line driver from onsemi, part of the 74ACT logic family. It operates from 4.5V to 5.5V, providing 24mA output current per channel. The device features two groups of four inverting buffers with independent enable pins and 3-State outputs. Packaged in a 20-pin SOIC, it is ideal for 5V TTL systems requiring high drive capability, such as bus interfacing, memory decoding, and industrial control. Its TTL compatibility simplifies integration.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTTL-Compatible Inputs: Directly interfaces with 5V TTL logic without extra components.\u003c\/li\u003e\n\u003cli\u003eHigh 24mA Output Drive: Ensures reliable signal transmission in high-capacitance environments.\u003c\/li\u003e\n\u003cli\u003e3-State Outputs: Allows multiple devices to share a common bus.\u003c\/li\u003e\n\u003cli\u003eInverting Function: Provides signal inversion, reducing external gate count.\u003c\/li\u003e\n\u003cli\u003eOptimized for 5V Systems: Perfect for legacy and industrial 5V applications.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e5V TTL Bus Interfacing\u003c\/h3\u003e\u003cp\u003eInterface between 5V microprocessors and memory or I\/O devices.
