Product details
Overview
MC74HC00AF from onsemi is a quad 2-input NAND gate in high-performance silicon-gate CMOS technology, pinout-compatible with LS00 TTL logic. It operates across 2–6 V supply, delivers ±25 mA output drive per pin, exhibits 10 LSTTL load capability, and supports −55°C to +125°C industrial temperature range - used for digital logic level translation and combinational control in embedded power management sequencers.
For engineers reviewing the MC74HC00AF datasheet, pinout, applications, or equivalent options, this page provides verified pin assignments, real-world timing behavior (13 ns max propagation delay at 6 V), DC electrical limits (VIH = 4.20 V min at VCC = 6 V), and automotive-qualified alternatives meeting AEC-Q100 requirements.
Technical Context
The MC74HC00AF implements four independent NAND gates in a single monolithic CMOS die, each with identical truth table behavior (Y = A·B̅). Its inputs tolerate both CMOS and LSTTL logic levels when pullup resistors are applied, enabling mixed-logic interfacing without level shifters.
It features rail-to-rail output swing, low input leakage (±1.0 µA max at 6 V), and high noise immunity due to CMOS threshold design. The device meets JEDEC Std. No. 7A and is Pb-free, halogen-free, and RoHS compliant.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC00DR | TI part; identical logic function and pinout; 15 ns max tPLH at 6 V vs. 13 ns for MC74HC00AF | Not AEC-Q100 qualified; rated only to +85°C ambient | Select when cost sensitivity outweighs automotive qualification and extended temperature needs |
| 74HC00PW,118 | Nexperia TSSOP-14 version; same AC/DC specs; 100% tested for 125°C operation | Same footprint as MC74HC00ADTR2G but lacks −Q suffix and PPAP documentation | Choose for space-constrained PCBs where TSSOP-14 is preferred and full automotive traceability is not required |
Compared with SN74HC00DR and 74HC00PW,118, the MC74HC00AF offers superior high-temperature performance (125°C guaranteed), documented AEC-Q100 compliance with PPAP support, and tighter propagation delay specification - making it the preferred choice for safety-critical automotive and industrial control designs requiring long-term reliability validation.

FAQ
What is the maximum operating temperature for MC74HC00AF?
The MC74HC00AF is fully specified from −55°C to +125°C ambient temperature. This rating is validated per JEDEC JESD22-A108 and applies to all DC and AC parameters in the datasheet. The MC74HC00AF maintains guaranteed timing and voltage thresholds across this full range, making it suitable for under-hood automotive use and industrial control cabinets without derating.
Is MC74HC00AF pin-compatible with standard TTL NAND gates?
Yes, the MC74HC00AF has identical pinout to the 74LS00 TTL NAND gate. All four gate inputs and outputs map one-to-one: pins 1–2–3 for first gate, 4–5–6 for second, 8–9–10 for third, and 12–13–11 for fourth, with VCC on pin 14 and GND on pin 7. This allows direct substitution in existing LS00 layouts without PCB modification.
Does MC74HC00AF require external pull-up resistors for TTL input compatibility?
Yes - when interfacing with LSTTL outputs, MC74HC00AF inputs require external pull-up resistors (typically 1–10 kΩ to VCC) to ensure valid high-level recognition, since LSTTL VOH (2.4 V) falls below the MC74HC00AF VIH minimum (3.15 V at VCC = 4.5 V). CMOS outputs drive directly without pull-ups.
What packaging options are available for MC74HC00AF?
The MC74HC00AF is offered in SOIC-14 (Case 751A) packaging, marked "HC00A", with Pb-free and RoHS-compliant construction. Tape-and-reel (2500 units) and rail (55 units) formats are available. The −Q automotive variant (e.g., MC74HC00ADR2G−Q) uses the same SOIC-14 package but includes AEC-Q100 test documentation and PPAP support.
How does MC74HC00AF handle unused inputs and outputs?
Unused inputs on the MC74HC00AF must be tied to either VCC or GND to prevent floating states that cause excessive current draw and logic instability. Unused outputs may be left open - no termination is required. This requirement is explicitly stated in the datasheet's Recommended Operating Conditions section (Note 3).
