onsemi MC10H100P

Overview

MC10H100P from ON Semiconductor is a quad 2-input NOR gate with strobe, implemented in MECL 10H logic family, operating at −5.2 V VEE supply, featuring 1.0 ns typical propagation delay, −1.95 V to −0.735 V output voltage swing, and 25 mW typical power per gate-used in high-speed digital control circuits such as ECL-based timing sequencers and bus arbitration logic.

For engineers reviewing the MC10H100P datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, PDIP-16 package mapping, strobe-controlled NOR functionality, temperature-stable noise margin (150 mV), and direct alternatives for legacy ECL system upgrades.

Technical Context

The MC10H100P implements four independent NOR gates sharing a common strobe input (Pin 9), each accepting two dedicated inputs (e.g., A1/A2, B1/B2) plus the global strobe-enabling synchronous enable/disable of all gates. Logic thresholds are voltage-compensated across 0°C to +75°C.

It operates exclusively with negative supply (VEE = −5.2 V ±5%), requires 50 Ω termination to −2.0 V, and meets MECL 10K™ compatibility while delivering improved noise margin (150 mV min) over full temperature range-critical for deterministic timing in backplane and instrumentation systems.

FAQ

What is the supply configuration required for MC10H100P?

The MC10H100P operates solely from a negative supply rail: VEE = −5.2 V ±5%, with Pins 1 and 16 (VCC1/VCC2) designated as no-connect. It requires 50 Ω termination to −2.0 V at outputs and does not use a positive VCC. This configuration is fundamental to MECL 10H operation and must be strictly followed to meet VOH/VOL specifications in the MC10H100P datasheet.

Does MC10H100P support true 3-input NOR logic per gate?

No. Each gate in the MC10H100P has two dedicated inputs (e.g., Pins 2 & 3 for Gate A) and shares Pin 9 as a common strobe input-functionally making it a 2-input NOR enabled by a third strobe signal. The device is correctly described as a "quad 2-input NOR gate with strobe", not a 3-input NOR. This architecture enables synchronous gating but does not provide independent three-input logic per gate.

Is MC10H100P pin-compatible with MC10H100L or MC10H100M?

No. MC10H100P (PDIP-16), MC10H100L (CDIP-16), and MC10H100M (SOEIAJ-16) share identical logic functionality and pin numbering, but differ in package type, thermal performance, and mounting method. While pin assignments match, mechanical compatibility (e.g., socket fit, reflow profile, creepage) is not interchangeable-PCB layout must match the specific package variant selected, including MC10H100P.

What is the guaranteed noise margin for MC10H100P across temperature?

The MC10H100P guarantees a minimum 150 mV noise margin over its full operating temperature range (0°C to +75°C) and supply voltage variation (VEE = −5.2 V ±5%). This value is measured as the difference between worst-case VIH and VIL thresholds and is explicitly validated-not typical-making it a design-critical parameter for noise-prone environments like backplanes or mixed-signal systems using MC10H100P.

Can MC10H100P be used in new designs given its legacy status?

Yes-MC10H100P remains actively supported by onsemi for legacy system repair, spares provisioning, and niche high-speed ECL applications where timing determinism outweighs power efficiency concerns. Its datasheet, packaging options (including Pb-free MC10H100PG), and availability through authorized distributors confirm ongoing manufacturability, making MC10H100P viable for new deployments requiring proven nanosecond-scale logic behavior.
