• Provides nondestructive hot insertion capability with high impedance glitch-free bus loading during power cycles.
• Features guaranteed output skew and separate control inputs that can be shorted for full 16-bit operation.

Buffers, Drivers, Receivers, Transceivers Applications

• Bus management systems requiring real-time and stored data multiplexing
• High-speed data transfer interfaces utilizing D-type flip-flops
• Parallel data routing applications with isolated A and B bus registers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering code suffix to confirm the package type, as the 74ABT16652 series includes both SSOP and TSSOP variants. Ensure the selected part matches the required lead count and physical dimensions for the target PCB footprint. Confirm RoHS compliance status through official manufacturer documentation prior to integration into production assemblies.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring simultaneous storage and real-time pass-through of 16-bit data streams. The dual-byte control architecture allows for flexible bus isolation and data latching without external logic. Consider the 64mA sink capability for driving heavy loads directly. Verify that the operating voltage aligns with the 4.5V to 5.5V specification to ensure proper logic level recognition and timing performance.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the ABT logic family, characterized by advanced BiCMOS technology designed for high-speed operations. It integrates sixteen bus transceiver circuits with D-type flip-flops, enabling complex data handling within a single integrated circuit. The design facilitates efficient bus management by allowing data to be stored or passed through based on specific control signals.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for compatible parts within the same ABT family offering identical pinouts and electrical characteristics. Verify that any substitute maintains the 56-lead SSOP form factor and supports the required 64mA output drive. Ensure the alternative device meets the same voltage and temperature specifications for direct replacement.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle data storage versus real-time transmission?

Data can be stored in the internal D flip-flops upon clock transitions or transmitted in real-time by enabling the output drivers while disabling the storage function, controlled by the SABn and SBAn select inputs.

What is the purpose of the separate control inputs for each byte?

The separate control inputs allow independent operation of the two 8-bit bytes. They can be shorted together to enable full 16-bit parallel operation or used separately for byte-level data manipulation.
