74HC245PW-Q100J

Overview

The Nexperia 74HC245PW-Q100J is an octal bus transceiver with 3-state outputs, housed in a TSSOP20 (SOT360-1) package. 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 CMOS low power dissipation, high noise immunity, and non-inverting outputs. It includes an output enable (OE) input for isolating buses and a direction control (DIR) input for managing data flow between Port A and Port B.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Octal bidirectional bus interface with non-inverting 3-state outputs
• Input levels compatible with CMOS logic specifications
• Latch-up performance exceeding 100 mA per JESD 78 Class II Level B

Applications

• Automotive electronic systems requiring Grade 1 component qualification
• Bidirectional data transfer between microcontrollers and peripheral devices
• Bus expansion interfaces in industrial control environments

Procurement Notes

Verify the specific ordering suffix matches the required package variant and temperature grade. Confirm that the automotive qualification status aligns with project requirements. Ensure compatibility with existing PCB footprint dimensions for the TSSOP20 package. Validate supply voltage ranges against system power rails before integration.

Selection Notes

Select this component when an octal bidirectional transceiver with automotive reliability is required. The HC logic family provides CMOS input levels suitable for standard digital interfaces. Consider the wide operating temperature range for harsh environment applications. Verify pinout compatibility if replacing legacy components in existing designs.

Part Context

This part belongs to the 74HC245-Q100 series, which is designed for automotive applications. It shares functional similarities with other 74-series bus transceivers but offers specific automotive-grade testing and reliability standards. The PW suffix indicates the TSSOP20 plastic thin shrink small outline package, providing a compact solution for space-constrained board layouts.

Replacement Considerations

Direct replacements include the 74HCT245PW-Q100J for TTL-compatible inputs or the 74AHC245PW-Q100J for higher speed performance. Verify logic level compatibility and propagation delay differences when substituting.
