SN65EL11DR

Clock Buffers, Drivers Overview

The SN65EL11DR is a PECL/ECL 1:2 fanout buffer manufactured by Texas Instruments. It operates within an ambient temperature range of -40°C to +85°C and is housed in an 8-pin SOIC package. The device accepts differential inputs and provides two complementary outputs, functioning as a low skew clock driver. It supports NECL mode with VCC at 0V and VEE ranging from -4.2V to -5.7V. The component is lead-free, RoHS compliant, and classified under the 65EL series.

Clock Buffers, Drivers Feature Summary

• PECL/ECL 1:2 Fanout Buffer configuration
• Differential input with complementary outputs
• Supports NECL mode (VCC = 0V, VEE = -4.2V to -5.7V)
• Low Skew Clock Driver logic IC type

Clock Buffers, Drivers Applications

• PECL/ECL signal distribution networks
• Clock buffering for high-speed digital systems
• NECL level translation and fanout

Clock Buffers, Drivers Procurement Notes

Verify the specific package variant, as the SN65EL11DGK denotes a VSSOP package while the DR suffix indicates an SOIC package. Confirm RoHS compliance status and moisture sensitivity level (MSL 1) requirements against current project specifications. Ensure voltage supply parameters align with PECL or NECL operational standards before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a single-ended or differential source requires splitting into two complementary PECL or ECL loads. Verify that the power supply rails match the specified VEE range for NECL operation if applicable. Consider the 8-SOIC footprint constraints during PCB layout compared to the VSSOP alternative.

Clock Buffers, Drivers Part Context

This part belongs to the SN65EL family of high-speed clock drivers. It serves as a buffer to maintain signal integrity across multiple destinations. Related variants include the SN65EL11DGK, which shares the same logical function but utilizes an 8-VSSOP package instead of the standard SOIC form factor.

Clock Buffers, Drivers Replacement Considerations

The SN65EL11DGK is a pin-compatible alternative offering the same 1:2 fanout functionality in a smaller VSSOP package. No other direct substitutes are confirmed in the provided data.
