MC10H123FNR2G

Inverter Gates Overview

The MC10H123FNR2G is a Triple 4-3-3-Input Bus Driver from the onsemi MC10H series. It consists of three NOR gates designed for bus driving applications on or between cards. The device features differential outputs with low logic levels specified at V_OL = -2.1 Vdc, allowing termination to -2.0 Vdc. When the output is low, emitter-followers turn off, presenting high impedance to eliminate bus discontinuities. It operates within a supply voltage range of 4.75V to 5.25V and supports a typical propagation delay of 1.5 ns.

Inverter Gates Feature Summary

• Triple 4-3-3-input NOR gate configuration optimized for bus driving
• Differential outputs with high-impedance state when low to prevent bus discontinuities
• Improved noise margin capability

Inverter Gates Applications

• Bus driving applications on circuit cards
• Inter-card bus connections
• Systems requiring 50 Ohm bus termination

Inverter Gates Procurement Notes

Verify component authenticity through authorized channels due to potential availability from secondary markets. Confirm RoHS compliance status as historical data indicates variations within the MC10H family. Ensure proper handling for moisture-sensitive devices if applicable. Validate package integrity upon receipt to ensure correct PLCC-20 pin alignment.

Inverter Gates Selection Notes

Select this component for designs requiring multiple NOR gates with specific bus termination characteristics. The differential output structure suits high-speed digital interfaces. Consider the 1.5 ns typical propagation delay for timing constraints. Verify that the -2.0 Vdc termination requirement aligns with the system's power distribution network.

Inverter Gates Part Context

Part of the MC10H ECL logic family, known for high-speed performance. The MC10H123 specifically addresses bus driver needs with configurable input structures. It complements other MC10H components like latches and flip-flops in complex digital systems.

Inverter Gates Replacement Considerations

Check for direct substitutes within the MC10H series such as the MC10H123FN. Verify pin compatibility and electrical specifications before substitution.
