Rated for -40°C to 85°C ambient, this transceiver is specified for factory-floor automation, outdoor telecom cabinets, and HVAC controllers. Not qualified to AEC-Q100, so avoid under-hood automotive or engine-bay deployment without additional screening.
TI lists the SN74LVCZ245APW as an active product. For production BOMs, this means no imminent requalification risk.
Each output can sink or source 24 mA, symmetrical at both high and low logic levels.
The SN74LVCZ245APW is from the 74LVCZ series, which features 5 V tolerant inputs on a 3.3 V supply. The standard SN74LVC245APW (74LVC series) does not offer 5 V tolerant inputs — its input voltage must not exceed the supply rail. If your design needs to interface a 3.3 V transceiver with a 5 V legacy bus, the 'Z' variant is the correct choice.
A functional peer is the SN74ABT2245DW, an 8-bit transceiver with 32 mA output drive and 4.5 V supply minimum — it operates at 5 V, not 3.3 V. The SN74LVTH16245ADGVR is a 16-bit dual-element transceiver with 2.7 V supply and 32 mA drive, but it is a different footprint (48-TSSOP). Neither is a pin-for-pin drop-in; verify pinout and supply compatibility before substituting.
