It provides bidirectional data flow between two 8-bit buses, controlled by a direction pin (DIR) and an output-enable pin (OE). The 3-state outputs let you isolate the device from the bus when it is not selected — standard for shared data lines in microprocessor or memory systems. Supply range is 4.5 V to 5.5 V, and the part is rated for industrial temperature environments from -40°C to 85°C. Output drive is 6 mA sink and source per channel, which is typical for HCT-family parts driving CMOS or TTL inputs on a backplane or peripheral bus. ## Through-hole DIP — still the right call for prototyping, repair, and legacy boards The 20-DIP (0.300\", 7.62 mm) package is a through-hole footprint that fits standard breadboards, prototyping boards, and existing PCB layouts designed for DIP sockets.","metaTitle":"SN74HCT245N 74HCT Transceiver, Non-Inverting, 20-DIP, Active","metaDescription":"SN74HCT245N from TI — 8-bit non-inverting bus transceiver with 3-state outputs, 4.5V–5.5V supply, 6mA drive, -40°C to 85°C.
