Product details
Overview
74AC08MTC from onsemi is a quad 2-input AND gate logic IC in a 14-lead TSSOP package, operating at 2.0–6.0V supply, with 7.5ns typical propagation delay (VCC = 3.3V), ±24mA output drive, and guaranteed VIH/VIL thresholds of 2.1V/0.9V at 3.0V VCC. It serves as a high-speed combinational logic element in digital control, address decoding, and bus gating circuits.
For engineers reviewing the 74AC08MTC datasheet, pinout, applications, or equivalent options, key selection criteria include its AC-family voltage flexibility (2.0–6.0V), rail-to-rail input compatibility, 24mA sink/source capability, and TSSOP-14 JEDEC MO-153 footprint for space-constrained PCBs.
Technical Context
The 74AC08MTC implements four independent 2-input AND gates using advanced CMOS technology, supporting TTL-compatible input thresholds only when VCC ≥ 4.5V. Its logic behavior follows standard Boolean AND truth tables with no internal latching or timing dependencies between gates.
It operates across –40°C to +85°C with guaranteed DC performance including VOH ≥ 2.9V and VOL ≤ 0.44V at IO = ±24mA (VCC = 3.0V/4.5V/5.5V), and features low ICC quiescent current (≤20µA at VCC = 5.5V) and input leakage ≤±1.0µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0V to 6.0V - supports mixed-voltage system interfacing (3.3V and 5V logic domains) |
| Propagation Delay (tPLH/tPHL) | 7.5ns / 7.0ns typ. @ VCC = 3.3V, CL = 50pF - enables reliable operation up to ~100MHz toggle rate in simple combinatorial paths |
| Output Drive Strength | ±24mA - sufficient to directly drive LEDs, small MOSFET gates, or multiple 74-series inputs without buffering |
| Input Thresholds (VIH/VIL) | 2.1V / 0.9V @ VCC = 3.0V - ensures robust noise margin (>0.6V) in 3.3V systems |
| Quiescent Supply Current | ≤20µA @ VCC = 5.5V - minimizes static power in battery-backed or always-on logic sections |
| Operating Temperature | –40°C to +85°C - qualified for industrial-grade embedded control and instrumentation environments |
Pinout & Package
74AC08MTC is housed in a 14-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153 compliant, 4.4mm wide, with 0.65mm lead pitch and exposed pad not present. Pin 1 is marked by a dot or beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 11, 12 | Input (A1/B1/A2/B2/A3/B3/A4/B4) | Eight dedicated logic inputs - each pair feeds one AND gate; all inputs tolerate VCC + 0.5V and support 125mV/ns minimum edge rate |
| 3, 6, 10, 13 | Output (Y1/Y2/Y3/Y4) | Four buffered AND outputs - each capable of sourcing/sinking 24mA while maintaining VOL ≤ 0.44V and VOH ≥ 2.9V |
| 7 | GND | Ground reference for all logic and power terminals - must be low-impedance connection to minimize switching noise |
| 14 | VCC | Positive supply rail - bypassing with 0.1µF ceramic capacitor near pin is required for stable high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| Low ICC Quiescent Current | Reduces standby power consumption to ≤20µA at 5.5V - critical for energy-sensitive control logic |
| TTL-Compatible Inputs | Accepts standard TTL voltage levels across full 2.0–6.0V VCC range - simplifies interface with legacy microcontrollers and peripherals |
| High Output Drive | ±24mA per output eliminates need for external drivers in moderate-load applications like LED indicators or enable lines |
| Wide Operating Voltage | 2.0–6.0V operation allows direct use in both 3.3V and 5V systems without level-shifting circuitry |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |
|---|---|
Use Scenario: Enabling/disabling sensor readout channels based on master enable signals in modular I/O racks. IC Role / Device Role / Timing Role: Combinatorial gating of analog-to-digital converter (ADC) channel selects and interrupt request lines. Use Value: Eliminates discrete transistor gating; leverages 24mA drive to directly assert open-drain bus lines without pull-up sizing concerns. | Use Scenario: Controlling power delivery to interior lighting zones via microcontroller GPIO with current-limited loads. IC Role / Device Role / Timing Role: Logic-level AND gate enabling PWM-driven LED strings only when both safety lock and dimming command are active. Use Value: Ensures fail-safe off-state via dual-input requirement; 3.3V-compatible thresholds match automotive MCU I/O without translation. |
| Medical Diagnostic Equipment Front Panel | Communications Baseband Signal Routing |
Use Scenario: Gating display backlight enable and touch controller interrupt signals in response to system wake-up events. IC Role / Device Role / Timing Role: Synchronizing user-interface activation with main processor readiness using two independent control bits. Use Value: 7.5ns propagation delay ensures sub-microsecond response; TSSOP-14 footprint saves board area in compact front-end assemblies. | Use Scenario: Selecting between primary and backup data paths in FPGA-based baseband processors during link retraining. IC Role / Device Role / Timing Role: Glue logic implementing path-select arbitration where both clock domain crossing and data validity flags must be true. Use Value: Rail-to-rail input tolerance accommodates varying signal swing from different PHY layers; low ICC avoids thermal impact in dense FPGA carrier designs. |
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 |
|---|---|---|---|
| SN74AC08PW | Same AC logic family, identical electrical specs, but in 14-lead TSSOP (PW suffix) per TI - pinout and package dimensions match 74AC08MTC exactly | No functional difference; suitable for second-source procurement in TI-aligned BOMs | Select when TI-sourced components are preferred or when cross-manufacturer qualification is already established |
| 74LVC08PW,118 | Lower VCC range (1.65–5.5V), higher speed (4.2ns typ.), but only ±24mA drive at VCC ≥ 4.5V; 3.3V-optimized | Better suited for 3.3V-only systems with tighter timing budgets; not recommended for 5V legacy interfaces | Choose for new 3.3V designs requiring faster propagation or lower dynamic power; verify VIH/VIL compatibility at target VCC |
Compared with SN74AC08PW and 74LVC08PW,118, the 74AC08MTC offers broader supply voltage support (2.0–6.0V) and proven interoperability with 5V TTL peripherals, making it optimal for mixed-voltage industrial control where backward compatibility and margin are prioritized over peak speed.

FAQ
What is the maximum supply voltage rating for the 74AC08MTC?
The 74AC08MTC has an absolute maximum supply voltage (VCC) rating of +7.0V, but its recommended operating range is 2.0V to 6.0V. Operation above 6.0V is not guaranteed and may compromise parametric performance or long-term reliability. For sustained use, keep VCC within the recommended range - the 74AC08MTC is fully characterized and specified at 3.0V, 4.5V, and 5.5V.
Does the 74AC08MTC support 3.3V logic systems?
Yes, the 74AC08MTC is fully compatible with 3.3V logic systems. At VCC = 3.0V, it guarantees VIH ≥ 2.1V and VIL ≤ 0.9V, providing >0.6V noise margin. Its propagation delay is 7.5ns (tPLH) and 7.0ns (tPHL) typical at 3.3V, and output drive remains ±24mA. The 74AC08MTC requires no level shifters when interfacing with 3.3V microcontrollers or FPGAs.
What is the pinout configuration of the 74AC08MTC?
The 74AC08MTC uses a standard 14-pin TSSOP layout: Pin 1 = A1, Pin 2 = B1, Pin 3 = Y1, Pin 4 = A2, Pin 5 = B2, Pin 6 = Y2, Pin 7 = GND, Pin 8 = A3, Pin 9 = B3, Pin 10 = Y3, Pin 11 = A4, Pin 12 = B4, Pin 13 = Y4, Pin 14 = VCC. This matches JEDEC MO-153 and is identical to industry-standard 74-series quad AND gate pinouts.
Can the 74AC08MTC drive LEDs directly?
Yes, the 74AC08MTC can drive LEDs directly due to its ±24mA output capability. When sinking current (LED anode to VCC, cathode to output), configure the output LOW to illuminate; when sourcing (LED cathode to GND, anode to output), drive HIGH. Always include a series current-limiting resistor - for example, a 150Ω resistor limits current to ~20mA at 5V. Confirm voltage drop and thermal dissipation per output in your design.
Is the 74AC08MTC RoHS-compliant and lead-free?
Yes, the 74AC08MTC is lead-free and complies with RoHS Directive 2011/65/EU. All packages, including the MTC14 TSSOP variant, meet JEDEC J-STD-020B reflow standards. The device carries no exemption codes and is suitable for environmentally regulated industrial and medical applications requiring full substance compliance.
