Product details
Overview
MC74HC08ADTR2 from onsemi is a quad 2-input AND gate in TSSOP-14 package, operating across 2.0–6.0 V supply, with propagation delay as low as 13 ns at 6.0 V and output drive capability of 10 LSTTL loads. It performs basic Boolean conjunction logic for digital control, signal gating, and enable functions in industrial timing and interface circuits.
For engineers reviewing the MC74HC08ADTR2 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, automotive-grade AEC-Q100 qualification status, TSSOP-14 mechanical dimensions, and direct alternatives for logic-level compatibility and supply voltage range matching.
Technical Context
The MC74HC08ADTR2 implements four independent 2-input AND gates using high-performance silicon-gate CMOS technology. Its inputs are compatible with standard CMOS outputs and-when pulled up-LSTTL outputs, enabling mixed-logic interfacing without level shifters.
It operates over –55 °C to +125 °C, supports rail-to-rail input voltage (0 to VCC), and features low input current (±0.1 µA typical) and high noise immunity. The device is Pb-free, halogen-free, RoHS compliant, and qualified to AEC-Q100 for automotive use.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC08PW | TSSOP-14, identical logic function and 2–6 V range, but not AEC-Q100 qualified | Lacks automotive qualification and extended temperature support (only rated to +85 °C) | Select when cost sensitivity outweighs automotive reliability requirements |
| MC74HCT08ADTR2G | Same pinout and package, but TTL-compatible inputs (4.5–5.5 V only); 19 ns max tPLH at 5 V | Requires strict 5 V supply; unsuitable for 3.3 V or wide-range systems | Choose only for legacy 5 V TTL bus interfacing where HC-level noise margins are unnecessary |
Compared with SN74HC08PW and MC74HCT08ADTR2G, the MC74HC08ADTR2 uniquely combines automotive qualification, full 2–6 V operation, and sub-15 ns propagation at 6 V - making it the sole option for ruggedized, multi-voltage digital gating in production automotive and industrial designs.

FAQ
What is the maximum operating temperature for MC74HC08ADTR2?
The MC74HC08ADTR2 is rated for continuous operation from –55 °C to +125 °C. This full industrial/automotive temperature range is validated per AEC-Q100 stress testing and applies across its entire 2.0–6.0 V supply range. The MC74HC08ADTR2 maintains specified propagation delay, output drive, and input threshold performance within these limits.
Does MC74HC08ADTR2 support 3.3 V logic systems?
Yes, the MC74HC08ADTR2 fully supports 3.3 V operation: its recommended supply range includes 3.3 V, and DC characteristics (VIH = 2.10 V min, VIL = 0.90 V max at VCC = 3.0 V) ensure clean interfacing with standard 3.3 V CMOS outputs. Input leakage remains ≤1.0 µA, and propagation delay is 30 ns max at 3.0 V - confirmed in the official onsemi datasheet Rev. 16.
Is MC74HC08ADTR2 pin-compatible with older 74LS08 devices?
Yes, the MC74HC08ADTR2 is explicitly designed to match the LS08 pinout across all 14 pins. This allows drop-in replacement in existing SOIC-14 or TSSOP-14 layouts originally designed for 74LS08, provided supply voltage and loading conditions align with HC-family specifications. The MC74HC08ADTR2 retains identical A1/B1/Y1 through A4/B4/Y4 assignments and VCC/GND locations.
What packaging format does MC74HC08ADTR2 ship in?
The MC74HC08ADTR2 ships in tape-and-reel format: 2500 units per reel, compatible with automated SMT placement equipment. The package is TSSOP-14 (Case 948G), with Pb-free terminations and RoHS compliance. Marking reads "HC 08A" per onsemi's generic marking diagram, and the −Q* suffix confirms AEC-Q100 qualification and PPAP capability.
Can MC74HC08ADTR2 drive LEDs directly?
No, the MC74HC08ADTR2 is not intended for direct LED driving. Its output current rating is ±5.2 mA max at VCC = 6.0 V - insufficient for most indicator LEDs requiring 10–20 mA. Additionally, the device lacks current-limiting circuitry and thermal protection. For LED control, use the MC74HC08ADTR2 to gate a dedicated LED driver or transistor switch, not as a direct source/sink.
