SN74AUCH16244GQLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AUCH16244GQLR is a 16-bit buffer/driver with 3-state outputs from the Widebus family. It operates at VCC voltages from 0.8V to 2.7V, optimized for 1.8V operation. The device features sub-1-V operability and supports mixed-mode signal operation with 3.6-V I/O tolerance. It includes bus hold on data inputs to eliminate external pullup/pulldown resistors. The GQL package is a VFBGA with 56 pins. Maximum propagation delay is 1.8 ns at 1.8V. Output drive is ±8 mA at 1.8V. Static current is 20 µA max.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Optimized for 1.8-V operation with 3.6-V I/O tolerance for mixed-mode applications
• Bus hold circuitry eliminates the need for external pullup or pulldown resistors
• Ioff circuitry supports partial-power-down mode by disabling outputs during power down
• Active bus-hold holds unused inputs at valid logic states

Buffers, Drivers, Receivers, Transceivers Applications

• 3-state memory address drivers
• Clock drivers
• Bus-oriented receivers and transmitters

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'GQLR' corresponds to the VFBGA package and tape-and-reel shipping format. Confirm that the component meets RoHS standards as indicated in the manufacturer's documentation. Ensure the operating temperature range of -40°C to 85°C aligns with system requirements. Check for any recent product life cycle notices regarding availability or obsolescence status.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-density 16-bit buffering with low voltage operation around 1.8V. The integrated bus hold feature simplifies design by removing external resistor requirements. Consider the VFBGA package constraints for PCB layout if space is limited. Verify that the 3.6-V I/O tolerance is sufficient for interfacing with higher voltage logic levels in mixed-signal environments.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AUCH16244 series within Texas Instruments' Widebus family. It is designed specifically for improving performance and density in digital circuits. The device provides symmetrical active-low output-enable inputs and true outputs. It is functionally equivalent to other 16-bit buffers but distinguished by its ultra-low voltage capability and specific packaging options like the VFBGA.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74AUCH16244 variants with different packages such as DGGR (TSSOP) or DGVR (TVSOP). Ensure pin compatibility and electrical specifications match before substitution. Verify that alternative parts support the same 0.8V to 2.7V operating range and I/O tolerance requirements.
