Product details
Overview
74AHCT08PW,112 from Nexperia is a quad 2-input AND gate IC with TTL-compatible inputs, operating from 4.5 V to 5.5 V supply, featuring overvoltage-tolerant inputs up to 5.5 V, balanced propagation delays (max 9.0 ns at VCC = 5 V, CL = 50 pF), and specified for -40 °C to +125 °C industrial temperature range. It serves as a level-translating logic gate in mixed-voltage digital control and interface circuits.
For engineers reviewing the 74AHCT08PW,112 datasheet, 74AHCT08PW,112 pinout, 74AHCT08PW,112 application, or 74AHCT08PW,112 equivalent, this device is selected for high-noise-immunity combinational logic in power management sequencers, microcontroller peripheral interfacing, and industrial I/O expansion where TTL-level compatibility and 125 °C operation are required.
Technical Context
The 74AHCT08PW,112 implements four independent AND gates in a single monolithic CMOS structure with Schmitt-trigger input action on all pins, enabling robust noise rejection. Its TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) ensure direct interoperability with legacy 5 V TTL outputs without external biasing.
Each gate delivers rail-to-rail CMOS output drive (VOH ≥ 3.7 V, VOL ≤ 0.55 V at IO = ±8 mA), supports 14-pin TSSOP packaging with 0.65 mm pitch, and maintains functional integrity across its full -40 °C to +125 °C operating range under stable 4.5–5.5 V supply conditions.
Key Specifications

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 |
|---|---|---|---|
| SN74AHCT08PWR | TI part in 14-pin TSSOP; VIH/VIL specs match but propagation delay slightly higher (max 10 ns vs 9 ns) | Identical pinout and function; validated for TI-specific qualification flow (AEC-Q100 Grade 3) | Select when TI supply chain alignment or automotive qualification is required |
| 74LVC08PW,118 | Nexperia LVC variant; 1.65–5.5 V supply; CMOS inputs (VIH = 0.7×VCC); lower drive (±24 mA) | Supports 3.3 V and dual-supply systems; unsuitable for pure 5 V TTL source interfacing | Choose for wider voltage flexibility and lower power in 3.3 V-centric designs |
Compared with SN74AHCT08PWR, the 74AHCT08PW,112 offers tighter propagation delay tolerance and native Nexperia 125 °C qualification; versus 74LVC08PW,118, it provides guaranteed TTL-level recognition but lacks sub-3 V operation - making it optimal for legacy 5 V logic integration where timing precision and noise immunity are critical.

FAQ
Is 74AHCT08PW,112 compatible with 3.3 V microcontroller GPIOs?
No - the 74AHCT08PW,112 requires a 4.5–5.5 V supply and has TTL-level inputs (VIH ≥ 2.0 V). While its inputs tolerate 3.3 V signals, driving it from a 3.3 V MCU output may fail to meet VIH minimum under worst-case VCC and temperature. Use 74LVC08PW,118 for true 3.3 V–5 V bidirectional interfacing.
Does the TSSOP14 package include thermal pad exposure?
No - the SOT402-1 (TSSOP14) package used for 74AHCT08PW,112 has no exposed thermal pad. Thermal dissipation relies on PCB copper area connected to pins 7 (GND) and 14 (VCC), with typical Ptot = 500 mW at ≤81 °C ambient before derating begins.
Can 74AHCT08PW,112 replace 74HC08 in existing 5 V designs?
Yes - with identical pinout and logic function, the 74AHCT08PW,112 substitutes for 74HC08 where TTL-level input compatibility is needed. Unlike HC, AHCT recognizes 2.0 V as HIGH, matching standard 5 V TTL outputs without external pull-ups or resistors.
What is the maximum capacitive load supported at 5 V supply?
The device is characterized up to 50 pF load capacitance (CL) with guaranteed tpd ≤ 9.0 ns. Driving >50 pF increases propagation delay nonlinearly and may cause marginal timing in high-speed paths; for >100 pF loads, add series termination or buffer staging per gate.
