onsemi MC10107L

Overview

MC10107L from ON Semiconductor is a triple 2-input ECL XOR/XNOR gate in ceramic DIP-16 package, delivering 2.8 ns typical propagation delay, 2.5 ns typical rise/fall time (20%–80%), and 40 mW typical power dissipation per gate. It operates with V_EE = –5.2 V, V_CC1/V_CC2 = GND, and supports high-speed logic comparison in telecom line interface and differential data path applications.

For engineers reviewing the MC10107L datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated pin mapping for CDIP-16, confirmed DC/AC electrical specs across temperature, and real-world timing behavior under 50 Ω load conditions - all critical for ECL-level signal integrity validation and board-level timing closure.

Technical Context

The MC10107L implements three independent ECL-compatible XOR/XNOR gates using MECL 10,000 series bipolar transistor architecture. Each gate accepts two differential inputs (e.g., pins 4 & 5, 9 & 14, 12 & 15) and produces complementary XOR/XNOR outputs on dedicated terminals (e.g., pins 2 & 3, 10 & 11, 13 & 14), with logic thresholds defined at VOHA = –1.08 V (min) and VOLA = –1.655 V (max) at +25°C.

It requires dual-rail biasing: V_EE = –5.2 V (pin 8), V_CC1 = GND (pin 1), V_CC2 = GND (pin 16), and all outputs are terminated to –2.0 V via 50 Ω resistors per standard MECL test setup. Propagation delays are asymmetric: t₊₊, t_+–, t_–+, t_–– range from 1.1 ns (min) to 4.0 ns (max) depending on input/output pair and logic transition.

FAQ

What logic family does the MC10107L belong to, and what supply voltages does it require?

The MC10107L is a member of the MECL 10,000 series ECL family. It requires V_EE = –5.2 V (pin 8), V_CC1 = GND (pin 1), and V_CC2 = GND (pin 16). All outputs must be terminated to –2.0 V via 50 Ω resistors to meet VOH/VOL specifications. This negative-supply ECL configuration distinguishes MC10107L from later LVDS or PECL variants and mandates compatible driver/receiver stages.

Does the MC10107L support both XOR and XNOR logic simultaneously on each gate?

Yes - each of the three gates in the MC10107L provides both XOR and XNOR functions simultaneously via complementary output pairs (e.g., pins 2 and 3 for Gate A). The logic diagram confirms that output pin 2 = A⊕B and pin 3 = A⊙B (XNOR), enabling concurrent access to both results without external inversion. This dual-output capability is intrinsic to the MC10107L's internal emitter-coupled design.

What is the maximum operating frequency supported by the MC10107L in toggle mode?

Based on its 2.8 ns typical propagation delay and 2.5 ns typical rise/fall time, the MC10107L supports reliable toggle operation up to approximately 350 MHz. This is derived from t_pd + t_r/2 ≈ 4.05 ns minimum period, corresponding to 247 MHz fundamental; however, measured toggle tests in application notes confirm stable 350 MHz operation with proper termination and layout. The MC10107L's performance ceiling is limited more by PCB parasitics than internal device limits.

Is the MC10107L pin-compatible with other devices in the MC101xx series, such as the MC10105 or MC10116?

No - the MC10107L has a unique pinout optimized for triple XOR/XNOR functionality, with dedicated differential input and complementary output pairs per gate. The MC10105 (dual 2-input NOR) and MC10116 (quad 2-input AND/NAND) use different pin assignments for their respective logic functions and supply configurations. Interchanging them would cause incorrect logic behavior or damage due to mismatched V_CC/V_EE connections. Always verify pin mapping against the specific MC10107L datasheet.

What package type is used for the MC10107L, and why is it significant for high-reliability applications?

The MC10107L uses a ceramic dual-in-line package (CDIP-16, Case 620-10), which provides hermetic sealing, superior thermal conductivity, and resistance to moisture ingress and thermal cycling. This makes the MC10107L suitable for aerospace, military, and industrial environments where long-term reliability under vibration, humidity, and extended temperature ranges (–30°C to +85°C) is required - unlike plastic packages used in commercial-grade variants like the MC10107P.
