Product details

Overview

MC14011BDT from onsemi is a quad 2-input NAND gate CMOS logic IC in TSSOP-14 package, operating across 3.0–18 VDC supply, delivering ±4.2 mA sink/source drive at 15 V, with propagation delay as low as 40 ns (VDD = 15 V, CL = 50 pF), and designed for low-power, high-noise-immunity digital control in industrial timing and interface circuits.

For engineers reviewing the MC14011BDT datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated pin mapping, confirmed electrical specs across temperature, real-world noise margin data, and two technically documented alternative parts for B-series CMOS NAND gate replacement scenarios.

Technical Context

The MC14011BDT implements four independent 2-input NAND gates using complementary MOS (CMOS) P- and N-channel enhancement-mode transistors on a single monolithic die. Each gate features buffered outputs and triple diode input protection-distinct from other B-series devices like MC14001B which use double diode protection.

It operates over −55 °C to +125 °C ambient, supports rail-to-rail input voltage (−0.5 V to VDD + 0.5 V), and maintains guaranteed VOL ≤ 0.05 V and VOH ≥ 4.95 V at VDD = 5 V, enabling direct interfacing with TTL loads without level-shifting.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Quad 2-input NAND - four independent gates, non-inverting output relative to NAND truth table
Supply Voltage Range	3.0 VDC to 18 VDC - enables single-supply operation across battery, industrial, and legacy 5/10/15 V systems
Propagation Delay	40 ns max at VDD = 15 V, CL = 50 pF - ensures reliable timing in sub-25 MHz combinatorial logic paths
Output Drive	±4.2 mA at VDD = 15 V - drives one low-power Schottky TTL load or two low-power TTL loads over full temp range
Input Thresholds	VIL = 4.0 V, VIH = 11 V at VDD = 15 V - provides 2.5 V DC noise margin, critical for noisy industrial environments
Quiescent Current	1.0 µA max per package at VDD = 15 V - enables ultra-low standby power in battery-backed control logic
ESD Protection	Triple diode input protection - higher robustness than standard B-series, matching MC14081B architecture

Pinout & Package

TSSOP-14 (DT suffix, Case 948G), 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad not electrically connected.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 5, 8, 9, 12, 13	Input A/B of NAND gates	Eight total inputs across four gates; unused inputs must be tied to VDD to prevent floating-induced shoot-through
3, 6, 10, 11	Output Y of NAND gates	Four buffered outputs; each capable of sourcing/sinking up to ±4.2 mA at 15 V without derating
7	VSS	Ground reference for all gates; must be low-impedance connection to minimize ground bounce in multi-gate switching
14	VDD	Positive supply rail; decoupling capacitor (0.1 µF ceramic) required within 5 mm for stable high-speed operation

Key Features

Feature	Design Value
Wide Supply Range	3.0–18 VDC operation eliminates need for multiple voltage regulators in mixed-supply systems
High Noise Immunity	2.5 V DC noise margin at 15 V ensures reliable operation in EMI-prone motor control or power supply feedback loops
Triple Input Protection	Enhanced ESD robustness (vs. double-diode variants) reduces field failure risk in handling-sensitive industrial assembly
Pin-for-Pin CD4000 Compatibility	Direct drop-in replacement for CD4011B in existing layouts, preserving PCB design integrity and qualification effort
Extended Temp Range	−55 °C to +125 °C operation supports deployment in automotive under-hood, aerospace, and outdoor infrastructure

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad 2-input NAND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
CD4011BM96	Same pinout, identical logic function, but rated only to +85 °C; lower drive strength (±3.6 mA @ 15 V)	Limited to commercial/industrial indoor use; unsuitable for extended temperature or high-current load scenarios	Select when cost sensitivity outweighs extended temp or drive requirements; verify layout thermal relief for SOIC package
74HC00DR	Higher speed (15 ns typ @ 5 V), but narrower 2–6 V supply range; no triple diode protection; TTL-compatible inputs	Better for 5 V high-speed digital systems; incompatible with 12/15 V rails or high-noise analog-adjacent zones	Choose for new 5 V designs requiring faster propagation; avoid in mixed-voltage or ESD-prone environments

Compared with CD4011BM96 and 74HC00DR, MC14011BDT uniquely balances wide-voltage operation, extended temperature capability, and enhanced input protection-making it the only option among the three qualified for 15 V industrial control and −55 °C cold-start applications.

FAQ

What is the maximum operating temperature for MC14011BDT?

The MC14011BDT is rated for continuous operation from −55 °C to +125 °C ambient temperature. This extended range is validated per the Absolute Maximum Ratings table and supported by electrical characteristics tested at −55 °C, 25 °C, and +125 °C. The TSSOP-14 package (Case 948G) maintains thermal integrity across this span when mounted per JEDEC standards.

Does MC14011BDT require external pull-up resistors on inputs?

No, MC14011BDT does not require external pull-up resistors on inputs. Unused inputs must be tied directly to VDD (not through a resistor) to prevent floating states that cause increased supply current and potential oscillation. This requirement is explicitly stated in the device documentation and applies to all NAND and AND gates in the B-series family.

Is MC14011BDT pin-compatible with CD4011BE?

Yes, MC14011BDT is pin-for-pin compatible with CD4011BE in the same TSSOP-14 footprint. Both share identical pin assignments (VDD = Pin 14, VSS = Pin 7, inputs/outputs mapped identically), and the MC14011BDT datasheet explicitly states "Pin-for-Pin Replacements for Corresponding CD4000 Series B Suffix Devices." Electrical behavior is functionally equivalent, though MC14011BDT offers superior noise margin and triple diode protection.

What is the typical supply current of MC14011BDT at 10 V?

At VDD = 10 V and 25 °C, the typical quiescent supply current (IDD) for MC14011BDT is 0.5 µA per package. Under dynamic conditions with CL = 50 pF and f = 1 MHz, total supply current IT ≈ (0.6 µA/kHz × 1000) + (0.5 µA ÷ 4) ≈ 600.125 µA - confirming ultra-low power consumption even during active switching.

Can MC14011BDT drive a standard 74LS00 input directly?

Yes, MC14011BDT can directly drive a 74LS00 input across its full operating range. At VDD = 5 V, its VOH ≥ 4.95 V and VOL ≤ 0.05 V exceed LS-TTL input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), and its output drive (±0.64 mA) meets LS-TTL loading requirements. The datasheet confirms capability to drive "two Low-power TTL loads or one Low-power Schottky TTL Load" over −55 °C to +125 °C.
