onsemi MC10197P

Overview

MC10197P from ON Semiconductor is a high-speed ECL hex AND gate with strobe capability, operating at –5.2 V VEE supply and delivering 2.8 ns typical propagation delay (B→Q), 3.8 ns (A→Q), and 2.5 ns typical rise/fall times (20%–80%) in a 16-pin PDIP package. It is used in ultra-fast digital logic systems such as mainframe CPU control paths and high-frequency test equipment.

For engineers reviewing the MC10197P datasheet, pinout, applications, or equivalent options, key selection criteria include its MECL 10,000-series compatibility, –1.06 V to –0.70 V VOH range, –1.89 V to –1.615 V VOL range, 200 mW typical package power dissipation, and dual VCC pins enabling independent biasing of input and output sections.

Technical Context

The MC10197P implements six independent AND gates with active-high strobe inputs per gate, using emitter-coupled logic architecture for sub-nanosecond switching. Each gate features differential input structure referenced to VEE = –5.2 V and supports termination to –2.0 V via 50 Ω loads.

It requires two separate positive supply connections-VCC1 (pin 1) for inputs and VCC2 (pin 16) for outputs-enabling optimized noise isolation and timing control. Logic thresholds are defined by VOHA (–1.205 V min at –30°C) and VOLA (–1.655 V max at –30°C), ensuring robust noise margins across temperature.

FAQ

What logic family does the MC10197P belong to, and what are its supply voltage requirements?

The MC10197P belongs to the MECL 10,000 series family and operates with VCC1 and VCC2 tied to GND, and VEE at –5.2 V. This negative-supply configuration defines its logic thresholds and output swing. The MC10197P requires precise 50 Ω termination to –2.0 V for specified timing and voltage performance. Its design assumes this termination condition, and deviations will impact propagation delay and noise margin.

How many independent AND gates does the MC10197P provide, and what is the function of the strobe input?

The MC10197P provides six independent AND gates, each with a dedicated strobe input that enables or disables the gate's output. Strobing allows synchronous evaluation of logic states across multiple gates, supporting pipelined architectures and time-gated signal processing. In the MC10197P, the strobe is implemented as an additional input per gate, requiring both operands and the strobe to be high for a high output.

What is the typical propagation delay of the MC10197P, and how does it vary between input paths?

The MC10197P has a typical propagation delay of 2.8 ns from B to Q and 3.8 ns from A to Q under standard test conditions (50 Ω load, –2.0 V termination). This asymmetry reflects internal path differences in the emitter-coupled transistor array. The MC10197P datasheet specifies these values separately because routing and fanout affect each path distinctly-designers must account for both when timing-critical paths span multiple inputs.

Can the MC10197P be used with modern 3.3 V or 5 V logic families?

No, the MC10197P is not directly compatible with TTL, CMOS, or LVDS logic families due to its –5.2 V VEE supply and negative-voltage output swing (VOH ≈ –0.8 V, VOL ≈ –1.7 V). Interfacing requires level-shifting circuitry such as ECL-to-TTL translators or resistor-based bias networks. The MC10197P is intended for use within fully MECL 10,000–based systems where all devices share the same supply and termination scheme.

What package type is used for the MC10197P, and how does it differ from the MC10197L and MC10197FN variants?

The MC10197P uses a plastic dual-in-line package (PDIP–16, Case 648), optimized for through-hole prototyping and serviceability. In contrast, the MC10197L uses a ceramic DIP–16 (Case 620) for enhanced thermal and environmental robustness, while the MC10197FN uses a 20-pin PLCC (Case 775) for surface-mount production. All three share identical logic functionality and DC/AC specifications, but differ in mechanical form factor, thermal resistance, and assembly method-so the MC10197P is selected primarily for ease of hand-soldering and field replacement.
