SN74SSTV16857DGGR

Specialty Logic Overview

The SN74SSTV16857 is a 3.3-V, 16-bit universal bus transceiver with configurable polarity and output enable control. It supports SSTL-2 and SSTL-3 I/O standards for high-speed data transmission. The device features a single-directional data path with independent output enables for each byte group. It includes Schmitt trigger inputs on the A side to tolerate slow input transitions. The DGGR package is a 56-pin TSSOP with an exposed pad for improved thermal performance.

Specialty Logic Feature Summary

• Supports SSTL-2 and SSTL-3 interface standards for system compatibility
• Configurable polarity allows flexible data direction control
• Schmitt trigger inputs provide noise immunity for slow signals
• Independent byte-group output enables offer granular control

Specialty Logic Applications

• High-density memory interfaces
• Buffering and bridging between different voltage domains
• Point-to-point or multi-drop bus architectures

Specialty Logic Procurement Notes

Verify the specific suffix (DGGR) matches the required package type and tape-and-reel quantity. Confirm that the operating temperature range meets your environmental specifications. Ensure the design accounts for the exposed pad thermal requirements during PCB layout. Cross-reference the manufacturer's latest datasheet for any pinout revisions or electrical characteristic updates before finalizing procurement.

Specialty Logic Selection Notes

Select this component when interfacing 3.3-V systems requiring SSTL termination levels. Consider the 16-bit width for parallel data paths. Evaluate the need for Schmitt triggers if input signals have slow rise times. Compare power consumption against other SSTLV families if low-power operation is critical. Verify that the TSSOP package fits within the available board space constraints.
