Product details
Overview
MC74ACT00DT from ON Semiconductor is a quad 2-input NAND gate in high-performance silicon-gate CMOS technology, operating at 4.5–5.5 V supply, delivering ±24 mA output drive, with propagation delays as low as 1.5 ns (tPLH/tPHL at 5.0 V), and designed for logic-level translation and digital signal conditioning in industrial control and instrumentation systems.
For engineers reviewing the MC74ACT00DT datasheet, pinout, applications, or equivalent options, this device serves as a TTL-compatible CMOS logic gate with guaranteed AC/DC performance across −55°C to +125°C, validated input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at 5.5 V), and robust ESD protection (>2000 V HBM).
Technical Context
The MC74ACT00DT implements four independent NAND gates using silicon-gate CMOS process technology, ensuring TTL-compatible input thresholds and output voltage levels while maintaining CMOS power efficiency. It features rail-to-rail output swing and operates with guaranteed timing over full military temperature range.
Its logic function Y = A·B is implemented with matched propagation delays (tPLH/tPHL ≤ 9.5 ns max at −55°C to +125°C, 5.0 V), input capacitance of 4.5 pF, and power dissipation capacitance of 30 pF - enabling predictable timing in synchronous digital systems and noise-immune combinatorial logic stages.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ACT00DR | Same logic function, identical AC/DC specs, SOIC-14 package (vs. TSSOP-14) | Larger footprint; better thermal dissipation but higher board area usage | Select when board layout prioritizes ease of hand-soldering or thermal margin over space constraints |

FAQ
What is the recommended operating voltage range for the MC74ACT00DT?
The MC74ACT00DT is specified for 4.5 V to 5.5 V DC supply operation. Operation outside this range - including below 4.5 V - may result in undefined logic thresholds, increased propagation delay, or failure to meet VIH/VIL specifications. The device is not rated for 3.3 V or dual-supply use.
Does the MC74ACT00DT support operation at −55°C?
Yes, the MC74ACT00DT is fully characterized and guaranteed to operate from −55°C to +125°C ambient temperature. All AC and DC parameters - including propagation delay, output drive, and input thresholds - are tested and specified across this full military-grade temperature range.
Is the MC74ACT00DT pin-compatible with the MC74AC00DT?
No, the MC74ACT00DT and MC74AC00DT are not functionally interchangeable despite identical pinouts. The MC74AC00DT operates from 2.0–6.0 V and has different input thresholds (VIH = 3.15 V min at 5.5 V), whereas the MC74ACT00DT is strictly 4.5–5.5 V with TTL-compatible thresholds (VIH = 2.0 V min). Swapping them risks logic misinterpretation.
What is the maximum capacitive load the MC74ACT00DT can drive reliably?
The MC74ACT00DT is characterized with CL = 50 pF in AC testing, and its 24 mA output drive supports loads up to ~70 pF while maintaining timing margins. For loads exceeding 50 pF, propagation delay increases linearly - e.g., 100 pF adds ~2.5 ns to tPLH/tPHL - and layout-dependent trace capacitance must be included in total CL calculation.
Does the MC74ACT00DT require external pull-up or pull-down resistors on unused inputs?
Yes. Unused inputs on the MC74ACT00DT must be terminated to VCC or GND via a resistor (typically 1–10 kΩ) to prevent floating states that cause increased ICC, noise susceptibility, or oscillation. Leaving inputs unconnected violates the Absolute Maximum Ratings and may degrade long-term reliability.
