SN65ELT23D

Translators, Level Shifters Overview

The SN65ELT23D is a dual differential PECL to TTL translator manufactured by Texas Instruments. It operates within a supply voltage range of 4.2 V to 5.7 V and supports data rates up to 500 Mb/s. The device features a propagation delay of 1.25 ns and functions reliably across an operating temperature range from -40°C to +85°C. Packaged in an 8-pin SOIC, it converts differential PECL inputs to standard TTL outputs for logic interfacing.

Translators, Level Shifters Feature Summary

• Converts differential PECL signals to single-ended TTL levels
• Supports high-speed data transmission up to 500 Mb/s
• Operates with a 5V power supply

Translators, Level Shifters Applications

• Interfacing PECL clock sources with TTL-based digital logic
• Level translation in high-speed communication systems
• Signal conversion in test and measurement equipment

Translators, Level Shifters Procurement Notes

Verify the specific package variant (SOIC-8) and ensure compatibility with 5V logic families. Confirm that the input signal amplitude matches the PECL standard requirements for reliable translation. Check for RoHS compliance status if required by your manufacturing standards. Ensure the operating environment stays within the specified -40°C to +85°C temperature range for optimal performance.

Translators, Level Shifters Selection Notes

Select this component when interfacing 5V PECL sources with TTL loads. It provides a direct solution for converting differential PECL outputs to single-ended TTL inputs without additional external components. Consider the 500 Mb/s data rate limit and 1.25 ns propagation delay for timing-sensitive designs. The SOIC-8 package offers a compact footprint suitable for dense PCB layouts.

Translators, Level Shifters Part Context

Part of the SN65ELT series, which includes various voltage level translators for different logic families. This specific model focuses on PECL to TTL conversion, distinguishing it from other variants like the SN65ELT20 (TTL to PECL) or SN65LVELT22 (LVTTL to LVPECL). It serves as a bridge between high-speed differential signaling and standard single-ended logic interfaces.

Translators, Level Shifters Replacement Considerations

SN65ELT23DR is the reel-pack equivalent of the tube-pack SN65ELT23D. SN65ELT23DGKR is the VSSOP-8 package variant offering a smaller footprint. Verify pinout compatibility before substituting with these alternatives.
