SN74SSTV16857DGVR

Specialty Logic Overview

The SN74SSTV16857DGVR is a 14-bit registered buffer manufactured by Texas Instruments, belonging to the SSTV logic series. It operates with a supply voltage range of 2.3 V to 2.7 V and supports a maximum clock frequency of 200 MHz. The device features a propagation delay of 2.8 ns and provides low-level output current of 20 mA and high-level output current of -20 mA. It is housed in a TVSOP-48 package and functions within an operating temperature range of 0°C to +70°C.

Specialty Logic Feature Summary

• Supports SSTL_2 data input with outputs compliant with SSTL_2 Class II specifications.
• Utilizes differential clock inputs (CLK and /CLK) for data latching on rising and falling edges.
• Includes a RESET input that disables receivers, resets registers, and forces outputs low.

Specialty Logic Applications

• Registered buffering for DDR memory interfaces
• High-speed data bus registration
• System board interconnects requiring SSTL_2 compatibility

Specialty Logic Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for obsolescence notices as this specific part may be discontinued or superseded by newer revisions. Ensure packaging integrity matches required reel or cut tape specifications for surface mount processing.

Specialty Logic Selection Notes

Select this component when designing systems requiring 14-bit registered buffering with SSTL_2 I/O standards. Ensure the design environment supports the specified 2.3 V to 2.7 V supply voltage range. Verify that the PCB layout accommodates the TVSOP-48 package dimensions and thermal requirements for the 0°C to +70°C operating range.

Specialty Logic FAQ

What type of clock input does the SN74SSTV16857DGVR use?

It uses differential clock inputs, specifically CLK and /CLK, to latch data on the rising edge of CLK and the falling edge of /CLK.

How does the RESET function operate in this device?

The RESET input disables the differential input receiver, resets all registers, and forces all outputs to a low state.
