74AHC245PW-Q100J

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC245PW-Q100J is an octal bus transceiver with 3-state outputs, packaged in a TSSOP20 (SOT360-1) plastic thin shrink small outline package. It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features balanced propagation delays, Schmitt-trigger inputs, and overvoltage tolerant inputs up to 5.5 V. It includes output enable (OE) and direction control (DIR) functions, with OE active LOW causing high-impedance OFF-states.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards for automotive applications
• Wide supply voltage range from 2.0 V to 5.5 V with CMOS low power dissipation
• All inputs feature Schmitt-trigger action and are overvoltage tolerant to 5.5 V
• High noise immunity with ESD protection exceeding 2000 V HBM and 1000 V CDM

Buffers, Drivers, Receivers, Transceivers Applications

• Automotive electronic systems requiring qualified logic components
• Mixed voltage environments utilizing overvoltage tolerant inputs
• Driving bus lines or buffering memory address registers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the datasheet lists multiple package options including SO20 and DHVQFN20 alongside the TSSOP20. Confirm that the AEC-Q100 Grade 1 qualification aligns with your automotive application requirements. Ensure input levels match the AHC series specifications rather than HCT when designing mixed-signal interfaces.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring an 8-bit bidirectional transceiver with automotive reliability. The TSSOP20 package offers space efficiency compared to standard SO packages. Consider the 2.0 V minimum supply voltage for low-power operation and verify that the 5.5 V input tolerance suits your highest signal voltage without external level shifting.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHC245-Q100 family, which also includes variants in SO20 and DHVQFN20 packages. The 'PW' designation specifically identifies the TSSOP20 form factor. The 'Q100J' suffix indicates automotive qualification and specific packaging details defined by the manufacturer's ordering system.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other 74AHC245 variants in TSSOP20 packages from Nexperia, such as the non-automotive 74AHC245PW. Cross-family substitutes like 74HCT245PW require checking TTL input compatibility and higher minimum supply voltage constraints.
