onsemi MC10H104P

Overview

MC10H104P from ON Semiconductor is a quad 2-input MECL 10H™ AND gate IC with one gate providing both AND and NAND outputs, 1.0 ns typical propagation delay, −5.2 V VEE supply, and PDIP-16 package. It delivers MECL 10K™ pinout and functional compatibility while improving propagation delay by 100% without increasing supply current, enabling high-speed logic in telecom clock distribution and ECL-based test equipment.

For engineers reviewing the MC10H104P datasheet, pinout, applications, or equivalent options, this page provides verified electrical specs, thermal-rated AC timing (0.45–1.9 ns tpd), noise margin (150 mV), voltage-compensated operation, and MECL 10K interoperability - all critical for deterministic high-speed digital design validation.

Technical Context

The MC10H104P implements four independent 2-input AND gates using MECL 10H differential emitter-coupled logic, with one gate offering complementary AND/NAND outputs. Its voltage-compensated design maintains stable switching thresholds across temperature (0°C to +75°C) and supply variation (VEE = −5.2 V ±5%).

All gates operate with guaranteed DC parameters including VIH/VIL windows (−1.17 V to −0.735 V high, −1.95 V to −1.45 V low) and output drive capability (±50 mA continuous), supporting termination into −2.0 V via 50 Ω resistors per standard MECL loading practice.

FAQ

What is the recommended power supply configuration for MC10H104P?

The MC10H104P requires a single −5.2 V supply applied to Pin 8 (VEE), with Pins 1 and 16 (VCC1/VCC2) connected to system ground (0 V). Decoupling capacitors (0.1 µF ceramic + 10 µF tantalum) must be placed within 10 mm of each VEE pin. No positive voltage is supplied - the "VCC" labels denote bias reference points, not active power rails. This configuration is mandatory to achieve specified VOH/VOL and propagation delay.

Does MC10H104P support true differential input operation?

The MC10H104P does not implement fully differential inputs like LVDS or PECL devices. It uses single-ended ECL inputs referenced to VEE, with defined VIH (−1.17 V to −0.735 V) and VIL (−1.95 V to −1.45 V) windows. Inputs accept either grounded-base transistor logic levels or properly terminated MECL waveforms, but lack internal differential pairs or common-mode rejection circuitry. Designers must ensure source impedance matching and avoid floating inputs.

Can MC10H104P drive 50 Ω loads directly?

Yes - the MC10H104P is characterized for driving 50 Ω loads terminated to −2.0 V, as specified in Table 2 and Figure 1 of the datasheet. Output voltage swing (VOH/VOL) and timing parameters are guaranteed only under this condition. Driving unterminated lines or mismatched impedances will degrade noise margin, increase rise/fall times, and risk violating VOH/VOL specifications. Always use series or parallel termination aligned with −2.0 V.

Is MC10H104P RoHS-compliant?

The MC10H104P suffix denotes the standard leaded PDIP-16 package. A Pb-free variant, MC10H104PG, is available with G suffix and marked per ON Semiconductor's Pb-Free Packaging Standard. The MC10H104P itself contains lead per exemption 7a (high-melting-temperature solder) and is not RoHS-compliant. For RoHS projects, specify MC10H104PG and verify board assembly reflow profile compatibility with matte tin finishes.

How does the dual-output gate (AND/NAND) in MC10H104P differ from the others?

Only Gate 1 (Pins 2–3 inputs, Pins 4–7 outputs) provides both true AND and complementary NAND outputs. Gates 2–4 (Pins 5–6, 9–10, 12–13 inputs) offer AND-only outputs (Pins 11, 14, 15). This architecture allows single-gate implementation of XOR/XNOR functions or synchronous enable/disable logic without external inversion. The NAND output shares the same propagation delay and drive strength as the AND output on that gate.
