SY100ELT21ZC

Translators, Level Shifters Overview

The SY100ELT21ZC is a single differential LVPECL-to-LVTTL translator manufactured by Microchip Technology. It operates on a single +3.3V power supply, requiring only VCC and ground connections due to the low voltage positive ECL input levels. The device features a typical propagation delay of 2.0ns and provides 24mA TTL outputs. It is housed in an 8-lead Small Outline Integrated Circuit (SOIC) package with flow-through pinouts. The component supports differential, single-ended, or AC-coupled interfaces and includes internal biasing for stability under open input conditions.

Translators, Level Shifters Feature Summary

• Translates differential LVPECL signals to LVTTL levels using a single 3.3V supply
• Provides high-drive 24mA TTL outputs for reliable signal integrity
• Features flow-through pinout design for simplified PCB layout
• Includes internal biasing circuitry to force output low during open input conditions

Translators, Level Shifters Applications

• Clock signal translation in high-speed digital systems
• Data signal level shifting between LVPECL sources and LVTTL receivers
• Space-constrained designs requiring low power and minimal footprint

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'ZC' against official Microchip documentation to confirm RoHS compliance and lead-free status, as suffixes often denote environmental or packaging variations. Ensure the procurement source is an authorized distributor to guarantee authenticity. Cross-reference the full part number with the manufacturer's current product status to confirm availability and lifecycle stage before finalizing orders.

Translators, Level Shifters Selection Notes

Select this component when interfacing LVPECL clock or data sources with LVTTL logic circuits. It is suitable for applications prioritizing low power consumption and small form factor within an 8-pin SOIC package. Verify that the system operates within the specified temperature range and that the 24mA output drive capability meets the load requirements of the downstream LVTTL devices.
