It operates from a 2V to 6V supply rail, covering both 3.3V and 5V logic domains in a single BOM line. Rated for -40°C to 85°C ambient, this part handles industrial temperature environments without derating the output drive. The 7.8 mA source and sink current per channel is typical for HC logic driving CMOS inputs or a single LSTTL load per line. ## Package and board integration Housed in a 20-SOIC wide-body package (0.209\", 5.30 mm body width), the SN74HC245NSR uses the standard 20-SO footprint with 1.27 mm pitch. The surface-mount package suits automated assembly, and the Tape & Reel packaging option feeds pick-and-place lines without reel changeover.","metaTitle":"SN74HC245NSR 74HC Transceiver, 8-Bit, 3-State, 20-SOIC","metaDescription":"Texas Instruments SN74HC245NSR 74HC octal bus transceiver, non-inverting, 3-state outputs, 2V-6V supply, -40°C to 85°C, 20-SOIC.
