Product details
Overview
MC74HC00AFR1 from onsemi is a quad 2-input NAND gate in high-performance silicon-gate CMOS technology, pin-compatible with LS00 TTL logic. It operates from 2 V to 6 V, delivers ±25 mA output drive per pin, exhibits 10 LSTTL load capability, and supports industrial temperature range (–55 °C to +125 °C) - used in digital control logic, power sequencing, and bus interface enable/disable circuits.
For engineers reviewing the MC74HC00AFR1 datasheet, pinout, applications, or equivalent options, this page provides verified functional specifications, validated TSSOP-14 package mapping, confirmed propagation delay (13 ns @ 6 V), input/output voltage thresholds, and real-world design context for logic-level translation and combinational gating.
Technical Context
The MC74HC00AFR1 implements four independent NAND gates using CMOS transistor pairs with rail-to-rail input compatibility - inputs accept voltages from GND to VCC and are compatible with both standard CMOS and LSTTL outputs when pullup resistors are applied. Its logic function Y = A·B is strictly defined per gate, with no internal feedback or latch behavior.
It features low static current (≤40 µA at 6 V), high noise immunity due to CMOS threshold margins, and guaranteed AC performance under CL = 50 pF loading: tPLH/tPHL ≤ 13 ns and tTLH/tTHL ≤ 13 ns at VCC = 6 V, enabling reliable use in 10 MHz+ synchronous logic systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 6.0 V - supports single-supply operation across 3.3 V and 5 V logic domains without level shifters. |
| Propagation Delay | 13 ns max @ VCC = 6 V, CL = 50 pF - enables timing-critical combinational logic in sub-25 MHz clock domains. |
| Output Drive | ±25 mA per pin - sufficient to directly drive LEDs, small relays, or fan-out to ≥10 LSTTL loads. |
| Input Leakage | ±1.0 µA max @ VCC = 6 V - ensures stable logic states with high-impedance inputs, critical for battery-powered systems. |
| Operating Temperature | –55 °C to +125 °C - qualified for automotive under-hood and industrial motor-control environments. |
| Input Capacitance | 10 pF max - minimizes capacitive loading on driving stages and preserves signal edge integrity. |
Pinout & Package
TSSOP-14 surface-mount package (Case 948G), 4.9 mm × 4.4 mm footprint, 0.65 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 9, 10, 12, 13 | Input A/B of NAND gates | Dedicated logic inputs - each pair (e.g., pins 1&2 → Y1) forms one NAND gate; unused inputs must be tied to VCC or GND. |
| 3, 6, 8, 11 | Output Y1–Y4 | Active-low open-drain–compatible outputs - capable of sourcing/sinking ±25 mA, require external pullups only for wired-AND. |
| 7 | GND | Ground reference for all I/O and supply - must be low-inductance connection to minimize switching noise. |
| 14 | VCC | Positive supply rail - bypassing with 0.1 µF ceramic capacitor near pin is mandatory for stable AC performance. |
Key Features
| Feature | Design Value |
|---|---|
| LS00 pinout compatibility | Enables drop-in replacement in legacy TTL designs without PCB modification or netlist changes. |
| CMOS/NMOS/TTL interfacing | Eliminates need for external level translators when interfacing mixed-logic-family systems. |
| AEC-Q100 qualification (NLV variant) | Validated for automotive applications including engine control modules and body electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC00DR | TI part; identical logic function and pinout, but SOIC-14 only (no TSSOP option); ICC max = 20 µA vs. 40 µA. | Preferred where board space permits SOIC and TI supply chain preference applies; not suitable for dense TSSOP layouts. | Select SN74HC00DR if SOIC-14 footprint is available and TI sourcing is required. |
| 74HC00PW,118 | Nexperia TSSOP-14 variant; same VCC range and speed, but specified only to +85 °C industrial grade (not –55 °C to +125 °C). | Limited to commercial/industrial ambient environments; unsuitable for automotive or extended-temperature industrial use. | Choose 74HC00PW,118 only for cost-sensitive non-automotive designs with <85 °C operating ceiling. |
Compared with SN74HC00DR and 74HC00PW,118, the MC74HC00AFR1 uniquely combines TSSOP-14 packaging, full –55 °C to +125 °C operation, and AEC-Q100 qualification - making it the sole option among the three for space-constrained automotive and harsh-environment industrial deployments.

FAQ
What is the maximum propagation delay of the MC74HC00AFR1 at 5 V supply?
The MC74HC00AFR1 has a maximum propagation delay of 15 ns at VCC = 4.5 V and CL = 50 pF, as specified in the AC Characteristics table. This value reflects worst-case tPLH/tPHL across temperature (–55 °C to +125 °C) and process variation, ensuring timing margin for synchronous logic design.
Is the MC74HC00AFR1 pin-compatible with TTL logic devices?
Yes, the MC74HC00AFR1 is pin-compatible with the 74LS00 TTL quad NAND gate. Its pinout matches LS00 exactly, and with appropriate pullup resistors on inputs, it interfaces directly with LSTTL outputs - enabling seamless migration from TTL to CMOS without layout changes.
Does the MC74HC00AFR1 support 3.3 V logic systems?
Yes, the MC74HC00AFR1 fully supports 3.3 V operation: its recommended VCC range is 2.0 V to 6.0 V, and all DC/AC specifications - including VIH = 2.1 V min and VOL = 0.26 V max at 3.0 V - are guaranteed across temperature, making it suitable for mixed-voltage 3.3 V/5 V system interfacing.
What is the input leakage current specification for the MC74HC00AFR1?
The MC74HC00AFR1 has a maximum input leakage current of ±1.0 µA at VCC = 6.0 V and TA = +125 °C, as stated in the DC Characteristics table. This low leakage ensures minimal power draw in high-impedance input configurations and supports battery-operated applications with strict quiescent current budgets.
Can unused inputs on the MC74HC00AFR1 be left floating?
No, unused inputs on the MC74HC00AFR1 must never be left floating. The datasheet explicitly requires tying all unused inputs to either VCC or GND to prevent undefined logic states, increased power consumption, and potential oscillation due to high-impedance CMOS inputs capturing noise.
