MC10EP451FAG

Flip Flops Overview

The MC10EP451FAG is a 6-bit fully differential D-type register from the onsemi 10EP series, housed in a 32-lead LQFP package. It operates with a clock frequency up to 3 GHz and supports both PECL (VCC = 3.0 V to 5.5 V) and NECL (VEE = -3.0 V to -5.5 V) logic families. The device features an asynchronous Master Reset input and internal 75 kΩ pulldown resistors on all inputs. Quiescent current ranges from 80 mA to 125 mA depending on supply voltage and temperature. Propagation delay from CLK to Q/Q outputs is typically 350 ps at 25°C.

Flip Flops Feature Summary

• 6-Bit Differential Register: Provides six independent D-type flip-flops with complementary differential outputs for high-speed data registration.
• Asynchronous Master Reset: Includes a single-ended MR input that asynchronously resets all flip-flops regardless of the clock state.
• High-Speed Performance: Supports clock frequencies up to 3 GHz with low skew characteristics (20 ps within-device, 35 ps device-to-device).
• Dual Logic Compatibility: Compatible with PECL (VCC = 3.0 V–5.5 V) and NECL (VEE = -3.0 V to -5.5 V) operating modes.

Flip Flops Applications

• High-frequency serial-to-parallel data conversion in telecommunications infrastructure.
• Clock distribution networks requiring registered output paths with minimal skew.
• Test and measurement equipment utilizing ECL-compatible signal processing.

Flip Flops Procurement Notes

Verify the specific ordering suffix 'FA' corresponds to the LQFP-32 package configuration as defined in the manufacturer's ordering information table. Confirm RoHS compliance status and moisture sensitivity level (MSL Level 2 for LQFP) prior to assembly planning. Ensure power supply decoupling meets the thermal resistance requirements specified for the LQFP-32 package under expected airflow conditions.

Flip Flops Selection Notes

Select the MC10EP451FAG when a 6-bit parallel output register is required with differential signaling capabilities. Compare against the MC100EP451 variant if higher drive strength or specific AC parameter tolerances are needed, though functional pinouts remain identical. Ensure the design accommodates the 125 mA maximum quiescent current draw at VCC = 5.5 V and provides adequate thermal management for the LQFP-32 package.

Flip Flops Part Context

This component belongs to the onsemi 10EP family of high-speed ECL logic devices. It shares the same logical function and pinout as the MC100EP451, differing primarily in electrical specifications such as drive current and propagation delay limits. The 'FAG' suffix indicates a Lead-Free LQFP-32 package supplied in tubes of 250 units.

Flip Flops Replacement Considerations

The MC100EP451FAG is a direct functional equivalent within the same package and pinout configuration. Verify that the application can tolerate the slight differences in DC and AC parameters between the 10EP and 100EP series variants before substitution.
