Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current Package Option Addendum to confirm the exact physical package type and moisture sensitivity level. Ensure that the selected variant matches the required lead finish and reflow temperature profile for the intended assembly process. Cross-reference the part marking code to validate authenticity and traceability during the procurement phase.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit buffering with mixed-voltage compatibility between 3.3-V and 5-V logic domains. The device is suitable for applications needing high-density bus drivers with low power consumption. Consider the 4.1 ns propagation delay for timing-critical paths. Verify that the thermal resistance characteristics of the TSSOP package align with the system's heat dissipation requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Widebus family of logic components designed for high-performance digital applications. It serves as a non-inverting buffer/driver capable of driving memory address buses, clock signals, and bus-oriented receivers. The architecture allows configuration as four 4-bit buffers, two 8-bit buffers, or one single 16-bit buffer depending on the enable pin usage.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle unused inputs?

The SN74LVCH16244A features active bus-hold circuitry that holds unused or undriven inputs at a valid logic state, eliminating the need for external pullup or pulldown resistors.

What is the function of the Ioff feature?

The Ioff circuitry disables the outputs when the device is powered down, preventing damaging current backflow through the device. This supports partial-power-down applications and live insertion.

Can this device translate voltages between different logic levels?

Yes, the inputs accept voltages up to 5.5 V while the device operates from 1.65 V to 3.6 V, allowing it to be used as a translator in mixed 3.3-V/5-V system environments.
