• High output drive capability supporting +64 mA and -32 mA loads
• Power-up 3-state function ensures safe initialization
• Latch-up protection exceeds 500 mA per JESD78B class II level A

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous two-way communication between data buses
• Bus-oriented transfers in high-speed digital systems
• Clock drivers and buffer applications requiring high drive strength

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the 'D' designation corresponds to the SO20 plastic small outline package. Confirm RoHS compliance status and check for any recent product discontinuation notices from NXP Semiconductors before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal bidirectional data transfer with independent direction control. The dual enable feature allows for data storage by simultaneous enabling of both OEAB and OEBA pins. Ensure the application environment stays within the recommended operating temperature range of -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ABT series of BiCMOS logic devices, known for combining low power dissipation with high speed. It serves as a bus transceiver alternative to standard TTL or CMOS buffers, offering superior drive strength and faster switching speeds suitable for modern high-performance digital interfaces.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible substitutes within the 74ABT family, such as the 74ABT623DB (SSOP20) or 74ABT623PW (TSSOP20), if package changes are acceptable. Verify electrical characteristics match requirements when considering cross-family replacements.
