The SN74LS645NSR is an octal bus transceiver designed for high-speed data communication. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range of 0¬8C to 70¬8C. This device features a non-inverting logic type with push-pull output, capable of driving output currents of 15 mA for high and 24 mA for low states. The transceiver is packaged in a 20-SOIC format suitable for surface mount applications. It is part of the 74LS series and is compliant with halogen-free standards. The product is intended for applications requiring reliable data transmission and is expected to remain available until at least 2031.
