{"product_id":"cd74fct244ctm","title":"CD74FCT244CTM","description":"\u003cp\u003eThe CD74FCT244CTM from Harris Corporation is a high-speed octal buffer with 3-State outputs, designed for 5V systems. Operating from 4.75V to 5.25V, it offers exceptional drive capability with 15mA source and 64mA sink current per output. This makes it ideal for driving LEDs, relays, and heavily loaded buses. The non-inverting architecture preserves signal polarity, and the 20-SOIC package provides a compact footprint. Its fast propagation delay and high output current make it a preferred choice for high-performance digital systems.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh Sink Current (64mA): Directly drives LEDs, relays, and low-impedance loads without external buffers.\u003c\/li\u003e\n\u003cli\u003eFast Propagation Delay: Minimizes signal latency in high-speed digital systems.\u003c\/li\u003e\n\u003cli\u003e3-State Outputs: Enables bus sharing and multiplexing in multi-device architectures.\u003c\/li\u003e\n\u003cli\u003eTTL-Compatible Inputs: Simplifies interfacing with legacy 5V TTL logic.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHigh-Current LED Driving\u003c\/h3\u003e\u003cp\u003eDrive high-power LEDs or LED arrays directly.
