Nexperia USA Inc. 74VHC08D,118

Overview

74VHC08D,118 from Nexperia is a quad 2-input AND gate IC in SO14 (SOT108-1) package, operating at 2.0–5.5 V supply with CMOS logic-level compatibility, 3.0 ns typical propagation delay at 5 V/15 pF, and rated for -40 °C to +125 °C industrial temperature range. It serves as a high-speed combinational logic building block in digital control, interface buffering, and address decoding circuits.

For engineers reviewing the 74VHC08D,118 datasheet, 74VHC08D,118 pinout, 74VHC08D,118 application, or 74VHC08D,118 equivalent, key selection criteria include input voltage tolerance beyond V_CC, Schmitt-trigger inputs for noise immunity, balanced t_PLH/t_PHL, ESD robustness (HBM >2000 V), and SO14 package compatibility with legacy LSTTL footprints.

Technical Context

This device implements four independent 2-input AND gates using high-speed Si-gate CMOS technology, fully compliant with JEDEC JESD7-A and pin-compatible with Low-power Schottky TTL. All inputs feature Schmitt-trigger action, enabling clean signal restoration on slow or noisy inputs.

It supports dual logic families: the 74VHC08 variant accepts CMOS-level inputs (VIH ≥ 3.85 V at V_CC = 5.5 V), while its 74VHCT08 counterpart (not this part) accepts TTL-level inputs (VIH ≥ 2.0 V). Input clamping current is ±20 mA, and output drive capability is ±8 mA at V_CC = 4.5 V.

FAQ

Can 74VHC08D,118 operate reliably at 3.3 V supply?

Yes. The 74VHC08D,118 is fully specified from 2.0 V to 5.5 V, with guaranteed performance at 3.3 V ±0.3 V. At this voltage, propagation delay is 4.0 ns (typ) with 15 pF load, VIH is 2.1 V min, and VOL remains ≤0.36 V at 4 mA sink - meeting common 3.3 V LVTTL and LVCMOS interface requirements without level shifting.

Does this device support mixed-voltage interfacing, e.g., 5 V inputs with 3.3 V supply?

Yes. Inputs tolerate voltages up to 7.0 V regardless of V_CC, allowing direct connection of 5 V signals to a 3.3 V-powered 74VHC08D,118. This eliminates external clamping diodes or resistors in mixed-supply systems, provided input current stays within ±20 mA absolute maximum ratings.

What is the significance of Schmitt-trigger inputs in this AND gate?

Schmitt-trigger inputs provide hysteresis (typically 0.3–0.5 V), enabling clean, bounce-free switching on slow-rising signals such as mechanical switch closures or RC-filtered sensor outputs. This prevents multiple output transitions during input slew, which is critical in debounce-free digital control and noise-prone industrial environments.

Is thermal derating required for continuous operation at +125 °C ambient?

Yes. For the SO14 (SOT108-1) package, total power dissipation derates linearly at 10.1 mW/K above +100 °C. At +125 °C, P_tot must be limited to 500 mW − (25 K × 10.1 mW/K) = 247.5 mW. This corresponds to ≤15 switching inputs at 1 MHz with 50 pF loads - verified via CPD = 10 pF and PD = CPD × V_CC² × f_i × N.
