MC10H351FNR2

Translators, Level Shifters Overview

The MC10H351FNR2 is a quad TTL/NMOS to PECL translator designed for interfacing saturated logic sections with PECL digital systems using a single +5.0 Vdc power supply. It features TTL/NMOS compatible inputs and PECL complementary open-emitter outputs, functioning as an inverting/non-inverting translator or differential line driver. The device includes a common strobe input that forces true outputs to the PECL low state and inverting outputs to the PECL high state when active low. Electrical characteristics specify a typical propagation delay of 1.3 ns, with a maximum operating frequency of 150 MHz. It operates within a temperature range of 0°C to +75°C and is housed in a PLCC-20 package.

Translators, Level Shifters Procurement Notes

Verify the exact ordering suffix to confirm packaging type, as the FNR2 designation indicates tape and reel shipping. Confirm RoHS compliance status for the specific batch, as older revisions may differ from current Pb-Free standards. Ensure the procurement channel provides valid traceability documentation for the PLCC-20 package. Check for any obsolescence notices regarding the MC10H351 series before finalizing orders.

Translators, Level Shifters Selection Notes

Select this component when a single +5.0 Vdc supply is required for both TTL/NMOS and PECL domains. Consider the 1.3 ns typical propagation delay for high-speed timing requirements. Evaluate the PLCC-20 package constraints against available PCB real estate. Verify that the 150 MHz maximum operating frequency meets system clock speeds. Ensure thermal management supports the specified 0°C to +75°C operating range.

Translators, Level Shifters Part Context

The MC10H351 belongs to the MECL 10H series of high-speed ECL-compatible logic devices manufactured by onsemi. This series focuses on providing robust voltage level translation and signal integrity for mixed-logic environments. The device complements other translators like the MC10H350 for complete differential signaling solutions. It represents a specialized solution for legacy TTL integration with modern PECL architectures.

Translators, Level Shifters Replacement Considerations

Check for direct pin-compatible replacements within the MECL 10H family. Verify if updated revisions of the MC10H351 are available with different packaging options. Ensure any substitute maintains the same PLCC-20 footprint and electrical specifications for seamless integration.
