Product details
Overview
74AHCT1G32GW,165 from Nexperia is a single 2-input OR gate logic IC with TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V), 5-pin TSSOP5 (SOT353-1) package, and operation across –40 °C to +125 °C. It delivers 3.3 ns typical propagation delay (CL = 15 pF, VCC = 5.0 V) and supports mixed-voltage interfacing via overvoltage-tolerant inputs up to 5.5 V. Used in level-shifting logic paths within industrial control I/O modules.
For engineers reviewing the 74AHCT1G32GW,165 datasheet, 74AHCT1G32GW,165 pinout, 74AHCT1G32GW,165 application, or 74AHCT1G32GW,165 equivalent, key selection criteria include TTL-level input compatibility, guaranteed operation at 5.5 V supply, thermal performance in TSSOP5 at +125 °C ambient, and verified output drive strength (±8 mA at VCC = 4.5 V).
Technical Context
This device implements a single 2-input positive-OR Boolean function (Y = A + B) using advanced CMOS process technology. Its TTL-compatible input stage accepts standard 5 V logic thresholds while maintaining full rail-to-rail output swing and symmetrical output impedance for balanced rise/fall times.
Designed for mixed-voltage system interfacing, it features overvoltage-tolerant inputs rated to 5.5 V independent of VCC, enabling safe connection to higher-voltage buses without external clamping. Propagation delays are characterized from –40 °C to +125 °C with CL = 15 pF and CL = 50 pF loads under specified VCC conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input OR gate (Y = A OR B); enables compact discrete logic implementation in space-constrained PCBs. |
| Supply Voltage Range | 4.5 V to 5.5 V; ensures compatibility with standard 5 V digital systems and tolerance against supply ripple. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V (VCC = 4.5–5.5 V); guarantees reliable recognition of TTL-family signal levels. |

Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package: 5-lead, 1.25 mm body width, 0.65 mm pitch, 1.1 mm × 2.2 mm footprint, 1.0 mm height. Pin 1 index located lower-left below marking "CG".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Data input | Second OR operand; accepts TTL/CMOS logic levels up to 5.5 V regardless of VCC. |
| 2 (A) | Data input | Primary OR operand; electrically identical to Pin 1; supports wired-OR expansion when used with open-drain drivers. |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry; must be low-impedance to minimize ground bounce in fast-switching applications. |
| 4 (Y) | Data output | OR result; rail-to-rail CMOS output capable of sourcing/sinking ±8 mA into resistive or capacitive loads. |
| 5 (VCC) | Supply voltage | Positive power rail; decoupling capacitor (100 nF X7R) required within 3 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | Valid VIH/VIL thresholds match legacy 74LS/74F families, enabling drop-in replacement in retrofitted 5 V logic designs. |
| Overvoltage-tolerant inputs | Withstands 5.5 V input signals even when VCC = 3.3 V or 2.5 V - eliminates need for external level translators in mixed-supply domains. |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures <10% duty-cycle distortion on square-wave outputs driving balanced loads. |
| High noise immunity | Input hysteresis margin >0.4 V at VCC = 5 V reduces susceptibility to crosstalk and EMI in dense routing environments. |
| Extended temperature range | Full parametric performance guaranteed from –40 °C to +125 °C - suitable for engine-control units and industrial motor drives. |

FAQ
Can 74AHCT1G32GW,165 operate with a 3.3 V supply?
No - the 74AHCT variant requires VCC ≥ 4.5 V to guarantee TTL-compatible input thresholds (VIH ≥ 2.0 V). At 3.3 V, input recognition is not assured per datasheet specifications. For 3.3 V operation, use the 74AHC1G32GW,165 variant instead, which supports 2.0–5.5 V with CMOS input levels.
What is the maximum capacitive load this OR gate can drive reliably?
The device is characterized up to 50 pF (Table 8), with typical tpd = 4.8 ns and max tpd = 10 ns at VCC = 5.0 V. Driving >50 pF increases propagation delay nonlinearly and may cause output ringing; for >100 pF loads, add a series resistor (22–47 Ω) near the output to dampen reflections.
Does the TSSOP5 package support automated optical inspection (AOI)?
Yes - the SOT353-1 package has exposed side-wettable flanks and standardized pad layout compliant with IPC-7351B. Its 0.65 mm pitch and 1.25 mm body width are fully supported by mainstream AOI systems when solder paste volume and reflow profile meet J-STD-020 moisture sensitivity level 1 requirements.
How does overvoltage tolerance work without external protection diodes?
Internal input structures incorporate integrated clamp diodes to VCC and GND, rated for continuous 5.5 V input voltage regardless of VCC level. This is validated per JEDEC JESD78 latch-up testing (>100 mA) and allows direct connection to 5 V buses even when powered from 3.3 V - no external components needed.
