{"product_id":"mc74hct245af","title":"MC74HCT245AF","description":"\u003cp\u003eThe MC74HCT245AF from onsemi is a non-inverting transceiver from the 74HCT logic family. It features a single channel of bidirectional data flow with 3-State outputs for bus isolation. Operating from 4.5V to 5.5V, it is designed for 5V TTL systems, with 6mA output drive capability. The device offers TTL-compatible inputs, making it a drop-in replacement for bipolar TTL transceivers. With a temperature range of -55°C to 125°C, it is suitable for military and automotive applications. Packaged in a 20-SOIC, this transceiver is ideal for 5V bus interfacing, data buffering, and signal routing.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTTL-Compatible Inputs:\u003c\/strong\u003e Directly interfaces with 5V TTL logic without level shifting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide Temperature Range (-55°C to 125°C):\u003c\/strong\u003e Suitable for extreme environments like automotive and aerospace.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-State Outputs:\u003c\/strong\u003e Enables bus sharing and prevents data corruption in multi-master systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBidirectional Data Flow:\u003c\/strong\u003e Simplifies bus design by allowing data transfer in both directions with a single IC.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e5V TTL Bus Transceiving\u003c\/h3\u003e\u003cp\u003eIn 5V digital systems, this transceiver enables bidirectional data flow between two buses, with 3-State control for bus isolation and multiplexing.\u003c\/p\u003e\u003ch3\u003eMicroprocessor System Data Bus\u003c\/h3\u003e\u003cp\u003eIt buffers the data bus between a microprocessor and memory or I\/O devices, reducing loading on the CPU and improving signal integrity.\u003c\/p\u003e\u003ch3\u003eIndustrial PLC I\/O Modules\u003c\/h3\u003e\u003cp\u003eIn programmable logic controllers, it interfaces between the main processor and I\/O modules, providing robust 5V signal transfer in noisy industrial environments.\u003c\/p\u003e\u003ch3\u003eLegacy System Interfacing\u003c\/h3\u003e\u003cp\u003eFor retrofitting older 5V TTL systems, this transceiver provides a reliable interface to modern components while maintaining 5V compatibility.\u003c\/p\u003e\u003ch3\u003eTest and Measurement Equipment\u003c\/h3\u003e\u003cp\u003eIn bench instruments, it routes data between multiple measurement modules and a central controller, with 3-State outputs for selective access.\u003c\/p\u003e\u003ch3\u003eAutomotive Body Control Modules\u003c\/h3\u003e\u003cp\u003eWith a -55°C to 125°C range, it is suitable for automotive body control modules that require reliable 5V bus communication.\u003c\/p\u003e\u003ctable\u003e\n\u003ccolgroup\u003e\u003ccol\u003e\u003c\/colgroup\u003e \u003ctbody\u003e \u003ctr\u003e \t\u003ctd\u003eProduct attributes\u003c\/td\u003e \t\u003ctd\u003eProperty Value\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eManufacturer\u003c\/td\u003e \t\u003ctd\u003eonsemi\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eProduct Series\u003c\/td\u003e \t\u003ctd\u003e74HCT\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003ePackaging\u003c\/td\u003e \t\u003ctd\u003eBulk | \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003ePart Status\u003c\/td\u003e \t\u003ctd\u003eActive\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eLogic Type\u003c\/td\u003e \t\u003ctd\u003eTransceiver, Non-Inverting\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eNumber of Elements\u003c\/td\u003e \t\u003ctd\u003e1\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eNumber of Bits per Element\u003c\/td\u003e \t\u003ctd\u003e8\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eInput Type\u003c\/td\u003e \t\u003ctd\u003e-\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eOutput Type\u003c\/td\u003e \t\u003ctd\u003e3-State\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \t\u003ctd\u003eCurrent -
