It provides eight non-inverting channels with 3-state outputs, each sourcing or sinking 8mA. ## Key ratings and what they mean for the BOM The 8mA output drive per channel is typical for the AHC family — enough to drive standard CMOS inputs, LEDs, or a few low-power loads, but not designed for high-fanout backplanes or long parallel buses. If your bus needs to drive more than a handful of loads, you will need to buffer or step up to the ABT or LVT families which offer higher current. The 3-state outputs allow multiple transceivers to share a bus line without contention, which is standard for multiplexed address/data buses in automotive ECUs or industrial controllers. ## Automotive qualification and temperature grade AEC-Q100 qualification means the part has passed the automotive stress tests for temperature cycling, moisture resistance, and operational life. The -40°C to 125°C range covers the full automotive temperature envelope — cabin, chassis, and under-hood. For designs that need to survive cold cranking or exhaust-adjacent heat, this grade is the floor, not the ceiling. ## Sourcing and lifecycle The SN74AHC245QDWRG4Q1 is listed as Active with ROHS3 compliance. No end-of-life notification or last-time-buy window is in effect. For volume production, this is a stable line item with no imminent obsolescence risk.","metaTitle":"SN74AHC245QDWRG4Q1 Automotive AEC-Q100 Octal Bus Transceiver","metaDescription":"TI SN74AHC245QDWRG4Q1 octal bus transceiver, non-inverting, 3-state outputs.
