Product details
Overview
MC74HC08ADTEL from onsemi is a quad 2-input AND gate CMOS logic IC in TSSOP-14 package, operating from 2.0 V to 6.0 V supply, delivering 5.2 mA output drive at 6.0 V, with propagation delay as low as 13 ns and input leakage ≤1.0 µA at 125°C - used in digital control signal conditioning for industrial PLC I/O modules.
For engineers reviewing the MC74HC08ADTEL datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range (2–6 V), guaranteed 10 LSTTL load drive, JEDEC Std. 7A compliance, and TSSOP-14 thermal performance (450 mW max at 25°C).
Technical Context
The MC74HC08ADTEL implements four independent AND gates using high-performance silicon-gate CMOS technology, with inputs compatible with both standard CMOS and LSTTL outputs (when pulled up). Its logic function Y = A·B is fully static, with no internal latching or clocking.
It operates across –55°C to +125°C, supports rail-to-rail input/output swing (0 to VCC), and features high noise immunity due to CMOS threshold design - confirmed by VIH ≥4.20 V and VIL ≤1.80 V at VCC = 6.0 V.

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 |
|---|---|---|---|
| SN74HC08DR | TI SOIC-14 package; 15 ns max tPD at 6 V; same VCC range and logic function | No TSSOP option; higher thermal resistance (500 mW vs 450 mW) limits high-density board use | Select when SOIC footprint is fixed and board space allows larger package |
| 74VHC08M | ON Semiconductor TSSOP-14; 10 ns max tPD at 5 V; lower ICC (0.1 µA typ) but narrower VCC range (2–5.5 V) | Not rated for 6 V operation; unsuitable for 6 V industrial sensor buses | Choose for speed-critical 3.3/5 V systems where 6 V tolerance is unnecessary |
Compared with SN74HC08DR and 74VHC08M, the MC74HC08ADTEL uniquely combines TSSOP-14 compactness, full 2–6 V operation, and JEDEC 7A compliance - making it optimal for space-constrained, wide-supply industrial control nodes requiring long-term availability.

FAQ
What is the maximum operating supply voltage for MC74HC08ADTEL?
The MC74HC08ADTEL supports a DC supply voltage range of 2.0 V to 6.0 V, with absolute maximum rating of –0.5 V to +7.0 V. Operation above 6.0 V risks permanent damage; sustained use at 6.0 V is fully characterized and supported across the full temperature range (–55°C to +125°C) per the datasheet's Recommended Operating Conditions table.
Is MC74HC08ADTEL pin-compatible with the 74LS08?
Yes, the MC74HC08ADTEL has identical pinout to the 74LS08, as explicitly stated in the datasheet: "The MC74HC08A is identical in pinout to the LS08." This allows direct PCB-level replacement when pull-up resistors are added to interface with LSTTL outputs, preserving layout and reducing redesign effort.
What is the output drive capability of MC74HC08ADTEL at 5 V supply?
At VCC = 5.0 V, the MC74HC08ADTEL delivers ±4.0 mA output current per pin (guaranteed), sufficient to drive 10 LSTTL loads. This is verified in the DC Characteristics table under VOH/VOL conditions with |Iout| ≤ 4.0 mA at VCC = 4.5 V, and confirmed by the "Output Drive Capability: 10 LSTTL Loads" feature statement.
Does MC74HC08ADTEL require external pull-up resistors for TTL input compatibility?
Yes - while MC74HC08ADTEL inputs are directly compatible with standard CMOS outputs, they require external pull-up resistors to interface with LSTTL outputs. The datasheet states: "with pullup resistors, they are compatible with LSTTL outputs," ensuring valid high-level recognition when driven by TTL logic.
What is the maximum propagation delay of MC74HC08ADTEL across temperature?
The maximum propagation delay (tPLH/tPHL) of MC74HC08ADTEL is 19 ns at VCC = 6.0 V over the full operating temperature range (–55°C to +125°C), as specified in the AC Characteristics table under the ≤125°C column. At 25°C, it is 13 ns, confirming consistent high-speed performance in extended-temperature deployments.
