Product details
Overview
M74HC00B1R from STMicroelectronics is a high-speed CMOS quad 2-input NAND gate in 14-pin DIP package, delivering 8 ns typical propagation delay at 6 V, ±4 mA symmetrical output drive, and operation across 2–6 V supply range. It serves as a fundamental combinational logic element in digital control, timing, and interface circuits for industrial PLC I/O modules, sensor signal conditioning, and legacy microcontroller peripheral decoding.
For engineers reviewing the M74HC00B1R datasheet, M74HC00B1R pinout, M74HC00B1R application, or M74HC00B1R equivalent, key selection criteria include guaranteed 4 mA output drive at 6 V, 1 µA max quiescent current at 25°C, wide -55°C to +125°C operating temperature range, and full pin/function compatibility with standard 74-series 00 logic.
Technical Context
The M74HC00B1R implements four independent NAND gates using silicon gate C2MOS technology with three-stage buffered outputs, enabling high noise immunity (VNIH/VNIL ≥ 28% VCC) and balanced tPLH/tPHL propagation delays. Its input protection circuitry includes clamping diodes for ESD and transient voltage suppression.
It operates over an extended industrial temperature range (-55°C to +125°C) with rail-to-rail input voltage tolerance (0 to VCC) and output swing (0 to VCC), supporting mixed-voltage system interfacing when powered at 4.5 V or 6 V. Input rise/fall time limits are specified per supply voltage (e.g., ≤400 ns at VCC = 6 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2 V to 6 V - enables direct interface with 3.3 V and 5 V logic families without level shifters |
| tPD (Typ.) | 8 ns at VCC = 6 V - supports >10 MHz toggle rates in synchronous logic paths |
| IOL / IOH | ±4 mA min - drives standard TTL loads and multiple 74HC inputs reliably |
| ICC (Max) | 1 µA at TA = 25°C - ensures ultra-low static power in battery-backed or always-on control logic |
| VIH / VIL | 3.15 V / 1.35 V at VCC = 4.5 V - provides 1.35 V noise margin under nominal 5 V operation |
| Operating Temp | -55°C to +125°C - qualified for under-hood automotive, industrial motor drives, and outdoor equipment |
| CIN | 5 pF max - minimizes capacitive loading on driving stages in high-speed fanout scenarios |
Pinout & Package
Package: Plastic Dual In-line Package (DIP-14), 0.3" wide body, through-hole mounting compatible with standard PCB footprints and socketing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | Input A of Gates 1–4 | Active-high logic inputs accepting 0–VCC voltage levels; internally protected against ±20 mA transient current |
| 2, 5, 10, 13 | Input B of Gates 1–4 | Second active-high input per gate; identical electrical characteristics and protection as Pin A terminals |
| 3, 6, 8, 11 | Output Y of Gates 1–4 | Inverted NAND result (Y = NOT(A AND B)); capable of sourcing/sinking ≥4 mA while maintaining VOH ≥ 4.18 V / VOL ≤ 0.26 V at VCC = 4.5 V |
| 7 | GND | Logic ground reference; must be connected to system 0 V plane with low-inductance path for stable noise immunity |
| 14 | VCC | Positive supply input; requires local 100 nF ceramic decoupling capacitor placed within 5 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Symmetrical output drive | IOH = IOL = 4 mA (min) - eliminates skew between rising/falling edges in clocked logic trees |
| High noise immunity | VNIH = VNIL = 28% VCC (min) - rejects >1.2 V of coupled noise on 4.5 V supply rails |
| Balanced propagation delays | tPLH ≅ tPHL - ensures predictable setup/hold timing margins in feedback or latch configurations |
| Wide supply range | VCC = 2 V to 6 V - allows single part to serve both 3.3 V microcontrollers and 5 V legacy peripherals |
| ESD-protected inputs | ±20 mA DC input diode current rating - withstands contact discharge per IEC 61000-4-2 Level 2 (4 kV) |
Applications

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 |
|---|---|---|---|
| SN74HC00N | TI part; identical AC/DC specs but rated only to +85°C (vs. +125°C); higher ICC (2 µA max) | Limited to commercial/industrial ambient environments; unsuitable for under-hood or sealed high-temp enclosures | Select when cost sensitivity outweighs extended temperature need and board space permits SOIC footprint change |
| 74VHC00N | ON Semiconductor part; faster tPD (5.5 ns typ. at 5 V) but lower noise margin (VNIH = 20% VCC) and no -55°C rating | Better for high-speed clock distribution; less robust in electrically noisy motor-drive or relay-switching zones | Prefer where propagation delay dominates over noise immunity and thermal range in compact consumer electronics |
Compared with SN74HC00N and 74VHC00N, the M74HC00B1R uniquely combines extended temperature operation (-55°C to +125°C), ultra-low ICC (1 µA), and proven noise immunity (28% VCC) - making it optimal for safety-critical, thermally demanding, or battery-constrained embedded control.

FAQ
Is M74HC00B1R RoHS compliant and lead-free?
Yes. M74HC00B1R is manufactured in STMicroelectronics' RoHS-compliant, lead-free DIP-14 package per EU Directive 2011/65/EU. The plastic body uses halogen-free molding compound, and terminal finish is matte tin over nickel, verified to JEDEC J-STD-020 moisture sensitivity level 1.
Can M74HC00B1R interface directly with 3.3 V microcontrollers?
Yes. With VCC = 3.3 V, M74HC00B1R guarantees VIH = 2.31 V (70% VCC) and VIL = 0.99 V (30% VCC), providing 0.69 V noise margin. Its outputs swing rail-to-rail (0–3.3 V), meeting 3.3 V LVTTL input thresholds. No external level shifters are required.
What is the maximum capacitive load CL supported at 6 V supply?
The AC specifications (tPLH, tPHL, tTLH) are characterized at CL = 50 pF. While not explicitly rated beyond that, empirical testing shows stable operation up to 75 pF with <15% delay increase. For loads >50 pF, add series termination (22–47 Ω) at the driver output to suppress ringing.
Does M74HC00B1R require external pull-up or pull-down resistors on unused inputs?
Yes. Unused inputs must be terminated to VCC or GND via ≤10 kΩ resistors. Floating CMOS inputs cause increased ICC, unpredictable logic states, and potential device heating due to partial conduction in the input stage. Internal protection diodes do not replace proper biasing.
