Product details
Overview
74AHC1G08W5-7 from Diodes Incorporated is a single 2-input positive AND gate in SOT25 package, operating from 2.0V to 5.5V supply, delivering ±8 mA output drive at 5.0V, with CMOS low power consumption and Schmitt-trigger inputs for noise-immune signal conditioning. It performs the Boolean function Y = A • B and is used in logic-level translation and signal gating within portable consumer electronics.
For engineers reviewing the 74AHC1G08W5-7 datasheet, 74AHC1G08W5-7 pinout, 74AHC1G08W5-7 application, or 74AHC1G08W5-7 equivalent, key selection criteria include input hysteresis margin (≥0.4 V at VCC = 3V), propagation delay ≤8.0 ns (CL = 15 pF, VCC = 5V), output drive capability, rail-to-rail input tolerance, and SOT25 thermal resistance (θJA = 195 °C/W).
Technical Context
The 74AHC1G08W5-7 implements a non-inverting combinational logic function with dual Schmitt-trigger inputs, enabling robust operation under slow-rising or noisy digital signals. Its push-pull output stage supports bidirectional current flow (±8 mA) and full rail swing (0 V to VCC) across the 2.0–5.5 V supply range.
Designed for compatibility with AHC logic family voltage thresholds, it meets JESD22 ESD ratings (2 kV HBM, 1 kV CDM, 200 V MM) and JESD78 latch-up immunity (>100 mA). Input transition rate tolerance is specified at 100 ns/V (VCC = 3.3 V) and 20 ns/V (VCC = 5 V), ensuring reliable timing across temperature (–40 °C to +125 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 5.5 V - enables direct interface with 3.3 V and 5 V systems without level shifters |
| Output Drive | ±8 mA at 5.0 V - sufficient to drive multiple 74AHC inputs or small capacitive loads (≤50 pF) |
| Propagation Delay | ≤8.0 ns (CL = 15 pF, VCC = 5 V) - supports >100 MHz toggle rates in short-path logic |
| Input Hysteresis | ≥0.4 V at VCC = 3 V - rejects noise up to 400 mV peak-to-peak on slow edges |
| Quiescent Current | ≤40 μA at VCC = 5.5 V - suitable for battery-powered always-on logic monitoring |
| ESD Rating | 2 kV HBM - exceeds IEC 61000-4-2 Level 2 for board-level handling robustness |
Pinout & Package
SOT25 (5-pin SC-74A) package with exposed pad not electrically connected; JEDEC-compliant footprint, 195 °C/W junction-to-ambient thermal resistance on standard FR-4 PCB with 2 oz copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data Input | Primary logic input with Schmitt-trigger threshold; accepts 0–VCC voltage range |
| B | Data Input | Secondary logic input with identical Schmitt characteristics; tolerant of slow edges |
| GND | Ground Reference | Return path for all internal currents; must be low-impedance for stable noise margin |
| Y | Logic Output | Push-pull CMOS output; drives high/low actively; no external pull-up required |
| Vcc | Power Supply | Single-supply rail; bypass capacitor (100 nF) recommended near pin for transient suppression |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable operation with slow or noisy signals (e.g., mechanical switch debouncing, sensor outputs) |
| Wide supply range (2.0–5.5 V) | Eliminates need for separate voltage regulators in mixed-rail systems (e.g., 3.3 V MCU + 5 V peripheral) |
| ±8 mA output drive | Drives ≥10 74AHC inputs or 30 pF trace capacitance without timing degradation |
| Low ICC (≤40 μA) | Reduces standby power in always-on status-monitoring circuits (e.g., lid-open detection, battery fuel gauging) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G08DBVR | Lower VCC min (1.65 V); higher max output drive (±32 mA); no Schmitt inputs | Preferred for 1.8 V systems; unsuitable for slow/noisy inputs without external filtering | Select when interfacing with 1.8 V logic and clean signal sources |
| 74AUP1G08GW,125 | Ultra-low ICC (≤0.9 μA); slower tPD (≤11 ns); Schmitt inputs retained | Better for battery life-critical applications; marginal for >50 MHz data paths | Select when sub-μA quiescent current outweighs speed requirements |
Compared with SN74LVC1G08DBVR and 74AUP1G08GW,125, the 74AHC1G08W5-7 uniquely balances Schmitt noise immunity, 5 V tolerance, and moderate speed-making it optimal for cost-sensitive 3.3/5 V mixed-signal interfaces where signal integrity cannot be assumed.

FAQ
What is the maximum operating temperature for continuous use?
The 74AHC1G08W5-7 has a rated operating free-air temperature range of –40 °C to +125 °C. At maximum ambient temperature, derating applies per θJA = 195 °C/W; junction temperature must remain ≤150 °C. For sustained 125 °C ambient, total power dissipation must stay below 128 mW (calculated as (150 – 125) / 195).
Can unused inputs be left floating?
No. Unused inputs must be tied to VCC or GND per datasheet Note 3. Floating inputs may cause increased ICC, oscillation, or unpredictable output states due to CMOS input structure sensitivity. For this device, tying to VCC ensures defined HIGH logic state and minimizes dynamic power consumption.
Is the SOT25 package lead-free and RoHS compliant?
Yes. The 74AHC1G08W5-7 uses lead-free finish and complies with EU Directive 2002/95/EC (RoHS), including all applicable exemptions. The molding compound is "green" (Br/Sb-free), and the device is marked per JEDEC standards with YU identification code and week/year date code.
Does this part support 1.8 V logic levels?
No. The minimum recommended supply voltage is 2.0 V. At 1.8 V, VIH and VIL thresholds fall outside specification, and output drive degrades significantly. For 1.8 V systems, consider SN74LVC1G08DBVR (1.65–5.5 V range) or 74AUP1G08GW,125 (0.8–3.6 V range), both with verified 1.8 V operation.
