Nexperia USA Inc. 74HCT2G08DP,125

Overview

74HCT2G08DP,125 from Nexperia is a dual 2-input AND gate logic IC operating at 4.5 V to 5.5 V supply, delivering TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), propagation delay of 14 ns (typ) at 5 V, and output drive capability of ±4.0 mA, used in digital signal routing and level translation within industrial control I/O modules.

For engineers reviewing the 74HCT2G08DP,125 datasheet, 74HCT2G08DP,125 pinout, 74HCT2G08DP,125 application, or 74HCT2G08DP,125 equivalent, this device supports robust interfacing between mixed-voltage logic domains, offers rail-to-rail output swing under load, and maintains stable operation across -40 °C to +125 °C ambient conditions.

Technical Context

This device implements two independent AND gates in a single TSSOP8 package, with inputs featuring integrated clamp diodes enabling safe interface to voltages exceeding VCC when used with current-limiting resistors. Each gate follows standard positive-logic AND truth table behavior with H/L-defined outputs.

It operates strictly as a combinatorial logic element-no internal latching, clocking, or state retention-and exhibits CMOS-level power efficiency (ICC ≤ 10 μA at VCC = 5.5 V, VI = VCC/GND) while maintaining TTL-compatible input voltage thresholds for seamless integration with legacy 5 V microcontroller peripherals.

FAQ

What is the maximum allowable input voltage when VCC = 5.0 V?

The absolute maximum input voltage is VCC + 0.5 V = 5.5 V, enabled by internal clamp diodes. Exceeding this requires external current limiting to keep IIK ≤ ±20 mA, as specified in Table 5. Operation above VCC without current limiting risks permanent damage.

Can 74HCT2G08DP,125 drive a 50 pF capacitive load at 10 MHz?

Yes-dynamic power calculation shows CPD = 10 pF, so PD ≈ 10 pF × (5 V)² × 10 MHz = 2.5 mW, well below the 250 mW Ptot limit for TSSOP8 at +25 °C. Propagation delay remains within spec (≤36 ns max at +125 °C), confirming functional integrity.

Is there any functional difference between 74HCT2G08DP and 74HCT2G08DC packages?

No functional difference-the DP (TSSOP8) and DC (VSSOP8) variants share identical electrical specifications, timing, and logic behavior. The distinction is purely mechanical: DP has 3 mm body width and 0.5 mm lead length; DC is narrower (2.3 mm) with shorter leads, suited for ultra-dense layouts.

Does this device support partial power-down or I/O isolation when VCC = 0 V?

No-74HCT2G08DP,125 lacks Ioff or power-down logic. With VCC = 0 V, inputs and outputs become high-impedance only if VI stays within -0.5 V to VCC + 0.5 V (i.e., -0.5 V to +0.5 V). Applying signals outside this range risks latch-up or damage due to unpowered clamp diode conduction.
