SN74AVC16244ZQLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AVC16244ZQLR is a 16-bit buffer/driver with 3-state outputs from the Texas Instruments AVC logic family. It operates at supply voltages (VCC) ranging from 1.4 V to 3.6 V, specifically designed for 1.65 V to 3.6 V applications. The device features overvoltage-tolerant inputs and outputs, supporting mixed-voltage-mode data communications up to 4.6 V. It includes Ioff circuitry for partial-power-down mode operation to prevent damaging current backflow. The package is a 56-pin VFBGA-ZQL.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• DOC (Dynamic Output Control) circuit dynamically changes output impedance to reduce noise without speed degradation.
• Overvoltage-tolerant inputs and outputs allow safe mixed-voltage-mode data communications.
• Ioff circuitry supports partial-power-down mode by disabling outputs to prevent backflow.
• Latch-up performance exceeds 100 mA per JESD 78, Class II standards.

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 ZQL suffix indicates the VFBGA package variant when sourcing. Confirm RoHS compliance and lead finish details against the latest TI Package Option Addendum. Ensure design-in checks cover the operating temperature range of -40°C to 85°C and voltage limits to avoid exceeding absolute maximum ratings.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for high-density bus applications requiring low propagation delay and noise reduction. The DOC feature is critical for systems sensitive to signal integrity during transitions. Ensure the design accommodates the 56-pin VFBGA footprint and thermal requirements specified in the mechanical data section.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Widebus family of 16-bit buffers. It complements other AVC series devices like the SN74AVC16244DGGR (TSSOP) and SN74AVC16244DGVR (TVSOP), offering the same electrical functionality in a compact ball grid array package suitable for space-constrained PCB layouts.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74AVC16244DGGR and SN74AVC16244DGVR are electrically equivalent alternatives in different packages. Verify pinout compatibility if replacing with non-TI equivalents, as functional mapping must match the 16-bit buffer configuration.
