onsemi MC14011BFR1

Overview

MC14011BFR1 from ON Semiconductor is a quad 2-input NAND gate CMOS logic IC designed for low-power, high-noise-immunity digital signal processing in industrial and embedded control systems. It operates across a 3.0–18.0 VDC supply range, delivers ±10 mA output drive per pin, features triple diode input protection, and is buffered to drive two low-power TTL loads over –55°C to +125°C.

For engineers reviewing the MC14011BFR1 datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated pin assignments for SOIC-14 (F suffix), confirmed electrical specs at multiple VDD levels, and real-world use context in noise-sensitive logic interfacing and level translation circuits.

Technical Context

The MC14011BFR1 implements four independent 2-input NAND gates using complementary MOS (CMOS) P- and N-channel enhancement-mode transistors on a single monolithic die. Its architecture enables rail-to-rail output swing and high input impedance, with guaranteed DC noise margins of 1.0 V (at 5 V), 2.0 V (at 10 V), and 2.5 V (at 15 V).

Each gate exhibits symmetric propagation delays - tPLH/tPHL = 125/160/200 ns (typical at 5/10/15 V, CL = 50 pF) - and supports dynamic operation up to ~1 MHz under typical loading. Input thresholds are defined by VIH ≥ 3.5 V (5 V), ≥7.0 V (10 V), ≥11.0 V (15 V) and VIL ≤ 1.5 V (5 V), ≤3.0 V (10 V), ≤4.0 V (15 V).

FAQ

What is the exact logic function implemented by MC14011BFR1?

The MC14011BFR1 implements four independent 2-input NAND gates. Each gate outputs LOW only when both inputs are HIGH; otherwise, the output is HIGH. This behavior is consistent across its entire operating range (3.0–18.0 VDC, –55°C to +125°C) and matches the truth table of standard CMOS NAND logic. The device contains no internal latching, memory, or programmability - it is purely combinational.

Does MC14011BFR1 require external pull-up or pull-down resistors on unused inputs?

Yes - all unused inputs of MC14011BFR1 must be tied to VDD (not left floating), as specified in the official datasheet. This prevents undefined logic states, excessive current draw, and potential oscillation due to high-impedance CMOS inputs. Pull-up resistors are unnecessary because direct connection to VDD ensures stable HIGH bias with zero static current.

What package type does MC14011BFR1 use, and is it RoHS compliant?

MC14011BFR1 uses a 14-pin EIAJ SOIC package (Case 965, F suffix), with 3.90 mm body width and gull-wing leads. Per ON Semiconductor's product change notifications and packaging documentation, this variant is RoHS compliant and halogen-free, meeting JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) requirements.

Can MC14011BFR1 safely interface with 5 V TTL logic outputs?

Yes - MC14011BFR1 can reliably accept 5 V TTL outputs as inputs. Its VIH minimum is 3.5 V at VDD = 5 V, and its input structure tolerates voltages up to VDD + 0.5 V. When powered at 5 V, the device interprets TTL HIGH (≥2.4 V) as valid logic HIGH, and its high noise margin (≥1.0 V) ensures immunity to TTL-level noise coupling.

What is the maximum capacitive load MC14011BFR1 can drive while maintaining specified timing?

MC14011BFR1's switching characteristics are characterized at CL = 50 pF. While it can drive higher capacitances, propagation delay increases linearly: tPLH/tPHL ≈ (0.26 ns/pF) × CL + 27 ns (at VDD = 15 V). For reliable timing at 100 pF, delay rises to ~53 ns - still within specification. However, sustained loads >100 pF may require buffering to avoid marginal timing or increased power dissipation.
