SN74SSTL16837ADGGR

Overview

The SN74SSTL16837ADGGR is a 20-bit universal bus driver designed for SSTL_3 interface applications. It operates with VCC and VDDQ supply voltages ranging from 3V to 3.6V, supporting SSTL_3 or LVTTL I/O levels. The device features a flow-through architecture and meets both SSTL_3 Class I and Class II specifications. It includes latch enable (LE) and clock (CLK) inputs for data storage, controlled by an output-enable (OE) input. The component is characterized for operation in the commercial temperature range of 0°C to 70°C.

Feature Summary

• Supports SSTL_3 signal inputs and outputs for high-speed memory interfaces
• Features a flow-through architecture optimized for PCB layout efficiency
• Includes latch/flip-flop functionality controlled by LE and CLK inputs
• Provides 3-state outputs with high-impedance states during power-up/down

Applications

• SSTL_3 Class I and Class II compliant memory systems
• High-speed data bus drivers requiring 20-bit parallel transfer
• Memory modules utilizing SSTL_3 signaling standards

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's current documentation to confirm pinout and electrical parameter alignment with your design requirements. Ensure that the DGG package dimensions match your PCB footprint constraints. Confirm that the operating voltage range of 3V to 3.6V aligns with your system's VCC and VDDQ supplies before finalizing procurement.

Selection Notes

Select this component when designing systems requiring a 20-bit wide data path with SSTL_3 compatibility. It is suitable for applications needing transparent mode operation or registered data storage via the LE and CLK pins. Consider the flow-through architecture if minimizing trace length and routing complexity on the PCB is a priority. Ensure the design supports the required VREF and VTT termination voltages for proper signal integrity.

Part Context

This device belongs to Texas Instruments' Widebus family, which provides high-density logic solutions for complex digital systems. The SN74SSTL16837A variant specifically targets memory interface applications where SSTL_3 signaling is mandated. It serves as a bridge between processor buses and memory components, facilitating reliable data transmission at high frequencies up to 200 MHz.

Replacement Considerations

Check for updated revisions within the SN74SSTL16837 series. Verify compatibility with other Widebus family members if system expansion is planned.
