Nexperia USA Inc. 74AHC1G32GW,165

Overview

74AHC1G32GW,165 from Nexperia is a single 2-input OR gate in TSSOP5 (SOT353-1) package, operating from 2.0 V to 5.5 V supply, with overvoltage-tolerant inputs up to 5.5 V, CMOS-level input thresholds, and guaranteed operation from –40 °C to +125 °C. It serves as a level-translating logic buffer in mixed-voltage I/O interfaces of microcontroller peripheral expansion circuits.

For engineers reviewing the 74AHC1G32GW,165 datasheet, 74AHC1G32GW,165 pinout, 74AHC1G32GW,165 application, or 74AHC1G32GW,165 equivalent, key selection criteria include input voltage tolerance, propagation delay at 3.3 V/5 V, output drive strength (±8 mA), thermal performance in TSSOP5, and compatibility with 3.3 V/5 V system-level signal conditioning.

Technical Context

This device implements a single positive-logic OR function (Y = A + B) using advanced CMOS process technology. Its overvoltage-tolerant inputs enable direct interfacing between 3.3 V logic domains and 5 V legacy buses without external level shifters.

Propagation delays are tightly balanced (tPLH ≈ tPHL), with typical values of 4.4 ns at VCC = 3.3 V/CL = 15 pF and 3.2 ns at VCC = 5.0 V/CL = 15 pF. Static characteristics include VIH = 3.85 V (min) and VOL = 0.36 V (max) at IO = 8.0 mA, ensuring robust noise margins in industrial control signal paths.

FAQ

What is the maximum recommended operating voltage for 74AHC1G32GW,165?

The absolute maximum supply voltage is +7.0 V, but the recommended operating range is 2.0 V to 5.5 V per datasheet Table 6. Operation above 5.5 V risks permanent damage and violates JEDEC JESD8-A specifications. At 5.5 V, VOH remains ≥3.85 V and VOL ≤0.55 V under load, ensuring reliable interface with 5 V CMOS receivers.

Can 74AHC1G32GW,165 safely interface a 5 V input signal while powered from 3.3 V?

Yes - its inputs are explicitly overvoltage tolerant to 5.5 V independent of VCC, as confirmed in Section 1 and Table 5. This allows direct connection of 5 V signals to Pins 1 or 2 when VCC = 3.3 V, with no external protection required, provided input current remains within ±20 mA limits.

Does 74AHC1G32GW,165 support hot-swap or live-insertion?

No - the device lacks explicit hot-swap control features such as power-on reset, input/output isolation, or slew-rate limiting. While its overvoltage-tolerant inputs improve robustness, uncontrolled insertion into a live 5 V bus may exceed IOK clamp current limits (±20 mA) and cause temporary malfunction or accelerated wear.

What is the thermal resistance (RθJA) of the TSSOP5 package?

RθJA for SOT353-1 (TSSOP5) is not directly specified, but total power dissipation is rated at 250 mW with linear derating: –3.3 mW/K above 74 °C ambient. At 125 °C, usable power drops to ~83 mW. For precise junction temperature estimation, use Ptot = (TJ – TA)/RθJA with RθJA ≈ 240 K/W derived from derating slope and max Ptot.
