Nexperia USA Inc. 74AHC1G08GW,165

Overview

74AHC1G08GW,165 from Nexperia is a single 2-input CMOS AND 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 and specified for -40 °C to +125 °C. It delivers symmetrical output impedance, balanced propagation delays (typ. 3.2 ns at 5 V, 15 pF), and low ICC (max 40 μA at 5.5 V). Used in voltage-level translation and logic interfacing within mixed-voltage microcontroller I/O expansion circuits.

For engineers reviewing the 74AHC1G08GW,165 datasheet, 74AHC1G08GW,165 pinout, 74AHC1G08GW,165 application, or 74AHC1G08GW,165 equivalent, key selection criteria include input voltage tolerance (5.5 V), propagation delay vs. load capacitance, output drive capability (±8 mA), thermal derating behavior above 74 °C, and compatibility with 3.3 V/5 V mixed-signal domains.

Technical Context

This device implements standard positive-logic AND functionality with TTL-compatible input thresholds only in the AHCT variant; the AHC version uses full CMOS input thresholds (VIH = 3.85 V min at VCC = 5.5 V). Its overvoltage-tolerant inputs enable direct connection to 5 V signals while powered from 3.3 V, eliminating external level-shifting components.

Propagation delay is characterized across temperature and supply voltage (2.0–5.5 V), with typical tpd of 4.6 ns at 3.3 V/15 pF and 3.2 ns at 5.0 V/15 pF. Power dissipation is minimized via CMOS architecture, with CPD = 17 pF and ICC < 1 μA at 25 °C under static conditions.

FAQ

Is 74AHC1G08GW,165 suitable for level translation between 5 V and 3.3 V systems?

Yes. Its overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC, allowing direct connection of 5 V signals to a 3.3 V-powered device. Output swing remains rail-to-rail (0 V to 3.3 V), making it ideal for unidirectional translation without external components or timing penalties.

What is the maximum allowable junction temperature and how does thermal derating work?

The device is rated for operation up to +125 °C ambient. For the TSSOP5 (SOT353-1) package, total power dissipation derates linearly at 3.3 mW/K above +74 °C. At 125 °C ambient, Ptot drops to ~83 mW from the 250 mW nominal rating, limiting continuous output current under worst-case thermal conditions.

Does 74AHC1G08GW,165 support hot-swap or live-insertion scenarios?

No. While inputs tolerate overvoltage, the device lacks explicit hot-swap protection features such as power-on reset, undervoltage lockout, or slew-rate controlled outputs. Applying VCC after inputs are driven may cause temporary contention or increased ICC until power stabilizes; proper power sequencing is required.

How does propagation delay vary with supply voltage and load capacitance?

tpd decreases with higher VCC and lower CL: at 5.0 V/15 pF it is 3.2 ns typ, rising to 8.0 ns max at 125 °C; at 3.3 V/50 pF it is 6.5 ns typ, increasing to 16.0 ns max. This voltage- and load-dependent behavior must be verified in final layout with actual trace capacitance and decoupling.
