{"product_id":"sn74act240pwle","title":"SN74ACT240PWLE","description":"\u003cp\u003eThe SN74ACT240PWLE is an octal inverting buffer\/line driver from Texas Instruments, part of the 74ACT logic family. It operates from 4.5V to 5.5V, delivering 24mA output current per channel. The device features two groups of four inverting buffers with independent enable pins and 3-State outputs. Housed in a compact 20-pin TSSOP package, it is ideal for 5V TTL systems requiring high drive strength, such as microprocessor bus buffering, memory decoding, and industrial control. Its small footprint is perfect for space-constrained PCBs.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCompact TSSOP-20 Package: Saves PCB space compared to SOIC alternatives.\u003c\/li\u003e\n\u003cli\u003eTTL-Compatible Inputs: Simplifies interfacing with 5V logic.\u003c\/li\u003e\n\u003cli\u003eHigh 24mA Output Drive: Ensures reliable operation in high-load conditions.\u003c\/li\u003e\n\u003cli\u003e3-State Outputs: Enables bus sharing in multi-device systems.\u003c\/li\u003e\n\u003cli\u003eInverting Function: Reduces need for external inverters.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e5V Microprocessor Bus Buffering\u003c\/h3\u003e\u003cp\u003eBuffer address\/data lines between a 5V CPU and memory.
