74HC245D-Q100J

Overview

The Nexperia 74HC245D-Q100J is an octal bus transceiver with 3-state outputs, designed for automotive applications under AEC-Q100 Grade 1 qualification. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features non-inverting data transfer controlled by Output Enable (OE) and Direction (DIR) inputs. It complies with JEDEC standards JESD8C and JESD7A, offering high noise immunity and low power CMOS dissipation.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 Grade 1 standards
• Wide operating temperature range extending up to +125 °C
• Bidirectional octal bus interface with non-inverting 3-state outputs
• High electrostatic discharge protection exceeding 2000 V via Human Body Model

Applications

• Automotive electronic systems requiring robust signal transmission
• Mixed voltage environments utilizing CMOS logic levels
• Industrial control systems operating across wide temperature extremes

Procurement Notes

Verify the specific package variant matches design requirements, as the D suffix denotes SO20. Confirm that the HC logic family aligns with system voltage thresholds, distinct from HCT TTL-compatible variants. Ensure compliance with AEC-Q100 Grade 1 is necessary for the target automotive application environment.

Selection Notes

Select this component when an 8-bit bidirectional interface is required in harsh automotive conditions. The HC series provides CMOS input levels suitable for standard logic families. Consider alternative packages like TSSOP or DHVQFN if board space constraints differ from the SO20 footprint dimensions.

Part Context

This part belongs to the Nexperia 74HC245-Q100 family of octal bus transceivers. It shares functional similarities with other members like the 74HCT245-Q100 but differs in input logic compatibility. The product line emphasizes automotive reliability and broad supply voltage flexibility for diverse embedded applications.

Replacement Considerations

Direct substitutes include other 74HC245 variants from different manufacturers meeting identical pinouts and electrical specifications. Verify that any replacement maintains AEC-Q100 Grade 1 certification if automotive usage is mandated.
