74AHCT245D-Q100J

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT245D-Q100J is an octal bus transceiver with 3-state outputs, designed for automotive applications. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features TTL input levels, balanced propagation delays, and overvoltage tolerant inputs up to 5.5 V. It includes Schmitt-trigger action on all inputs for high noise immunity and low CMOS power dissipation. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM).

• Overvoltage tolerant inputs allowing operation in mixed voltage environments.
• High noise immunity provided by Schmitt-trigger action on all inputs.

Buffers, Drivers, Receivers, Transceivers Applications

• Automotive electronic systems requiring robust signal transmission.
• Mixed voltage interface circuits utilizing TTL logic levels.
• Industrial control systems operating under high noise conditions.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'J' against official Nexperia documentation to confirm package and tape-and-reel specifications. Ensure the design accounts for the recommended operating conditions, specifically the 4.5 V to 5.5 V supply voltage range. Confirm that the SO20 plastic small outline package (SOT163-1) meets the thermal and mechanical requirements of the target application environment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-compatible inputs are required for an octal bus architecture. The device is suitable for designs needing high noise immunity and overvoltage tolerance at 5.5 V. Consider the extended temperature range capability if the application operates in harsh automotive or industrial environments. Verify that the 3-state output configuration aligns with the system's bus management requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC(AHCT)245-Q100 family of octal bus transceivers. It shares functional similarities with other members like the 74AHCT245PW-Q100J but differs in package type. The D suffix indicates the SO20 package, while the Q100 designation confirms its automotive grade qualification. It serves as a bidirectional data translator within digital logic systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHCT245PW-Q100J is a verified alternative offering identical electrical functionality in a TSSOP20 package. Designers must verify pinout compatibility and thermal performance differences between the SO20 and TSSOP20 packages before substitution.
