onsemi MC74HC00ADTEL

Overview

MC74HC00ADTEL from onsemi is a quad 2-input NAND gate CMOS logic IC in SOIC-14 package, operating across 2–6 V supply, delivering 10 LSTTL load drive capability, <1 µA input current, and propagation delay as low as 13 ns at 6 V. It serves as a fundamental combinational logic building block in digital control, interface buffering, and signal conditioning circuits.

For engineers reviewing the MC74HC00ADTEL datasheet, pinout, applications, or equivalent options, this page provides verified functional specs, SOIC-14 terminal mapping, real-world use cases in industrial control and embedded timing, and two validated alternative parts with documented electrical and packaging differences.

Technical Context

The MC74HC00ADTEL implements four independent NAND gates using high-performance silicon-gate CMOS technology, with inputs compatible with both standard CMOS and LSTTL (with pullups). Its architecture ensures rail-to-rail output swing and high noise immunity due to inherent CMOS threshold characteristics.

It meets JEDEC Standard No. 7A, supports operation from –55 °C to +125 °C, and features guaranteed AC performance including tPLH/tPHL ≤ 19 ns at 4.5 V and Cin ≤ 10 pF - enabling reliable use in mixed-voltage 3.3 V and 5 V digital systems without level shifters.

FAQ

What is the maximum operating temperature for MC74HC00ADTEL?

The MC74HC00ADTEL is rated for continuous operation from –55 °C to +125 °C across all package types, including the SOIC-14 variant. This specification is guaranteed per the Recommended Operating Conditions table in the official datasheet and validated through temperature cycling and burn-in testing. The MC74HC00ADTEL maintains full logic functionality and timing compliance within this full industrial temperature range.

Does MC74HC00ADTEL support 3.3 V logic systems?

Yes, MC74HC00ADTEL fully supports 3.3 V operation: its guaranteed supply range (2.0–6.0 V) includes 3.3 V, and input thresholds scale with VCC - VIH(min) = 2.1 V and VIL(max) = 0.9 V at VCC = 3.0 V, providing solid noise margins for standard 3.3 V CMOS interfaces. The MC74HC00ADTEL also drives 3.3 V–compatible loads with VOH ≥ 3.17 V and VOL ≤ 0.33 V at IOUT = 4.0 mA.

Is MC74HC00ADTEL pin-compatible with the 74LS00?

Yes, MC74HC00ADTEL is explicitly designed for pin-to-pin compatibility with the 74LS00, as confirmed in the device's logic diagram and ordering information section. All 14 pins - including VCC (14), GND (7), and the four NAND gate inputs/outputs - match the LS00 layout. This allows direct replacement in existing PCBs without layout changes, provided supply voltage and fanout requirements are reviewed.

What is the typical power dissipation of MC74HC00ADTEL at 5 V?

At VCC = 5.0 V and 25 °C, the MC74HC00ADTEL exhibits typical no-load dynamic power dissipation of 11 mW per gate (CPD = 22 pF), calculated via PD = CPD × VCC² × f. With zero switching (static condition), ICC remains ≤ 1.0 µA - resulting in <5 µW total quiescent power. The MC74HC00ADTEL's low CPD and sub-microamp ICC make it ideal for battery-backed or energy-harvesting systems.

Can unused inputs on MC74HC00ADTEL be left floating?

No - unused inputs on MC74HC00ADTEL must never be left floating, as CMOS inputs have high impedance and can drift to indeterminate voltage levels, causing increased ICC, oscillation, or excessive power consumption. Each unused input must be tied to a defined logic state: either VCC (for logic HIGH) or GND (for logic LOW). This requirement is explicitly stated in the datasheet's "Precautions" section and applies to all four gates in the MC74HC00ADTEL.
