Product details
Overview
SN74LS00ML1 from ON Semiconductor is a quad 2-input NAND gate logic IC in SOEIAJ-14 package, operating at 4.75–5.25 V supply, with guaranteed output low current of 8.0 mA and propagation delays of 9–15 ns (tPLH/tPHL), used in TTL-compatible digital control and interface circuitry.
For engineers reviewing the SN74LS00ML1 datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed VIL ≤ 0.8 V, VOH ≥ 2.7 V at IOH = –0.4 mA, VOL ≤ 0.4 V at IOL = 4.0 mA, and ESD tolerance > 3500 V - all critical for legacy industrial control and board-level signal conditioning designs.
Technical Context
This device implements four independent TTL-compatible NAND gates using low-power Schottky (LS) bipolar technology. Each gate has standardized input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) and rail-to-rail compatible output drive capability under 5 V operation.
It operates across 0°C to +70°C ambient temperature with guaranteed DC performance including IIH ≤ 20 µA at VIN = 2.7 V and IIL = –0.4 mA at VIN = 0.4 V, ensuring reliable noise margin and fan-out compatibility in mixed-logic systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4.75 V to 5.25 V - ensures stable operation within standard TTL supply tolerance. |
| VOH (min) | 2.7 V at IOH = –0.4 mA - guarantees HIGH-level compatibility with downstream LS/TTL inputs. |
| VOL (max) | 0.4 V at IOL = 4.0 mA - maintains LOW-level noise margin for cascaded logic stages. |
| tPLH / tPHL | 9–15 ns - defines maximum propagation delay for timing-critical combinational logic paths. |
| Input Clamp Voltage | –1.5 V - protects inputs against negative transients up to –0.65 V typical. |
| ESD Rating | >3500 V - meets human-body model (HBM) requirements for handling robustness. |
Pinout & Package
SN74LS00ML1 is housed in a 14-pin SOEIAJ (Small Outline EIAJ) plastic package (Case 965), surface-mount compatible with gull-wing leads and 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 11, 12 | Input A/B per NAND gate | Eight total inputs across four independent 2-input NAND gates. |
| 3, 6, 10, 13 | Output Y per NAND gate | Four open-collector compatible outputs with active-low logic function. |
| 7 | GND | Ground reference for all internal circuitry and output sinking paths. |
| 14 | VCC | +5 V supply connection for biasing all four gates and output drivers. |
Key Features
| Feature | Design Value |
|---|---|
| Quad 2-input NAND function | Four fully independent gates on one die - reduces board space vs discrete gate solutions. |
| Low-power Schottky (LS) process | Reduces power consumption vs standard TTL while retaining speed and drive strength. |
| Guaranteed VIH/VIL thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V - ensures interoperability with legacy 74-series TTL families. |
| Output short-circuit protection | IOS = –20 to –100 mA - limits damage during transient overloads without external components. |

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 |
|---|---|---|---|
| SN74LS00N | Dual-in-line package (14-pin PDIP), same electrical specs but through-hole mounting. | Used where manual assembly or socket-based prototyping is required. | Select when board assembly uses through-hole processes or requires socket testing. |
| SN74LS00D | SOIC-14 package (Case 751A), identical logic function and DC/AC specs, different leadform and body dimensions. | Preferred for high-density surface-mount production with standard SOIC reflow profiles. | Choose for automated SMT lines where SOIC-14 is the established footprint. |
Compared with SN74LS00N and SN74LS00D, SN74LS00ML1 offers identical logic behavior and electrical performance but differs in mechanical form factor - SOEIAJ-14 provides tighter width and distinct lead geometry, making it suitable for Japanese-standard PCB layouts and legacy equipment service replacements where EIAJ compliance is specified.

FAQ
What is the supply voltage range for SN74LS00ML1?
The SN74LS00ML1 operates over a guaranteed supply voltage range of 4.75 V to 5.25 V. This tight tolerance ensures compatibility with regulated 5 V TTL power rails and prevents malfunction due to ripple or droop. The device's ICC values (1.6 mA HIGH, 4.4 mA LOW) are specified at VCC = MAX, confirming stable current draw across this range. SN74LS00ML1 must not be operated outside these limits to maintain guaranteed timing and logic thresholds.
Does SN74LS00ML1 support direct replacement for other 74LS00 variants?
Yes - SN74LS00ML1 shares identical logic function, DC electrical characteristics, and AC timing specs with all SN74LS00 variants. Its SOEIAJ-14 package matches the pinout of the standard 14-pin dual-in-line and SOIC versions, though mechanical dimensions differ. SN74LS00ML1 is intended for drop-in replacement in EIAJ-compliant footprints, but PCB land patterns must match Case 965 specifications, not DIP or SOIC.
What is the maximum output sink current for SN74LS00ML1?
The SN74LS00ML1 guarantees an output low current (IOL) of 8.0 mA per gate, with VOL ≤ 0.5 V measured at that load. This allows driving multiple LS-TTL inputs (fan-out ≥ 20) or small LEDs with series resistors. Exceeding 8.0 mA risks violating VOL spec or thermal limits. For higher current needs, external buffers or MOSFET drivers should be used alongside SN74LS00ML1.
How does SN74LS00ML1 handle input noise or negative transients?
SN74LS00ML1 includes integrated input clamp diodes with a guaranteed clamp voltage (VIK) of –1.5 V, protecting against negative spikes down to –0.65 V typical. This feature suppresses ESD events and ground bounce without external components. Combined with VIL ≤ 0.8 V and VIH ≥ 2.0 V, SN74LS00ML1 achieves a noise margin of ≥0.4 V for both logic states - essential in electrically noisy industrial environments.
Is SN74LS00ML1 RoHS compliant?
SN74LS00ML1 was manufactured prior to mandatory RoHS implementation and is not RoHS compliant - it contains lead in solder and packaging materials per its 2001 datasheet revision. ON Semiconductor discontinued RoHS conversion for legacy 74LS parts. For new designs requiring RoHS, consider modern alternatives like SN74LVC00A, but note SN74LS00ML1 remains available for repair and legacy compliance use cases.
