Nexperia USA Inc. 74AHCT1G08GW,165

Overview

74AHCT1G08GW,165 from Nexperia is a single 2-input AND gate logic IC with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), 5-pin TSSOP5 (SOT353-1) package, −40 °C to +125 °C operating range, and propagation delay of 3.6–8.0 ns (CL = 15–50 pF, VCC = 4.5–5.5 V). It serves as a level-translating combinational logic element in mixed-voltage digital control paths.

For engineers reviewing the 74AHCT1G08GW,165 datasheet, 74AHCT1G08GW,165 pinout, 74AHCT1G08GW,165 application, or 74AHCT1G08GW,165 equivalent, key selection criteria include TTL-level input compatibility, overvoltage-tolerant inputs up to 5.5 V, symmetrical output drive (±8 mA), industrial temperature support, and low dynamic power dissipation (CPD = 19 pF).

Technical Context

This device implements a single 2-input AND function with true CMOS output structure and TTL-compatible input switching thresholds-enabling direct interface with legacy 5 V TTL logic while operating from a 4.5–5.5 V supply. Its overvoltage-tolerant inputs (rated to 5.5 V independent of VCC) allow safe operation in mixed-supply systems where input signals may exceed VCC.

The logic core delivers balanced tPLH/tPHL propagation delays, symmetrical output impedance, and latch-up immunity exceeding 100 mA per JESD78 Class II Level A. Static and dynamic characteristics are fully specified across −40 °C to +125 °C, supporting automotive under-hood and industrial control applications requiring robust timing behavior.

FAQ

Is 74AHCT1G08GW,165 pin-compatible with 74AHC1G08GW,165?

Yes - both share identical TSSOP5 (SOT353-1) pinout: Pin 1 = B, Pin 2 = A, Pin 3 = GND, Pin 4 = Y, Pin 5 = VCC. However, they differ electrically: 74AHCT1G08GW,165 uses TTL input thresholds (VIH = 2.0 V), while 74AHC1G08GW,165 uses CMOS thresholds (VIH = 3.85 V @ VCC = 5.5 V). Swapping requires verification of source logic family.

Can 74AHCT1G08GW,165 operate with VCC = 3.3 V?

No - the 74AHCT variant is specified only for VCC = 4.5 V to 5.5 V per Table 6. At 3.3 V, input thresholds fall outside TTL specification (VIH minimum becomes undefined), and output drive degrades significantly. For 3.3 V operation, use 74AHC1G08GW,165 or 74LVC1G08DBVR instead.

What does "overvoltage tolerant input" mean for this device?

It means each input (A and B) can safely accept DC voltages from −0.5 V to +5.5 V regardless of the applied VCC value (4.5–5.5 V), without damage or unintended conduction. This allows connection to higher-voltage signals (e.g., 5 V buses) even when the local VCC is at nominal 5 V - critical for mixed-supply board-level integration.

Does 74AHCT1G08GW,165 support hot-swap or live-insertion?

It supports limited hot-swap behavior due to overvoltage-tolerant inputs and robust ESD protection (HBM > 2000 V, CDM > 1000 V), but lacks explicit hot-swap features like slew-rate controlled outputs or undervoltage lockout. For reliable hot-swap, add series current-limiting resistors and ensure VCC ramps before input signals - per Nexperia Application Note AN10727.
