Nexperia USA Inc. 74HC30D-Q100J

Overview

74HC30D-Q100J from Nexperia is an automotive-grade 8-input NAND gate in SO14 package, operating from 2.0 V to 6.0 V supply, qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C), with CMOS-level inputs, 26 ns typical propagation delay at 4.5 V, and input clamping diodes enabling overvoltage-tolerant interfacing in body control modules.

For engineers reviewing the 74HC30D-Q100J datasheet, 74HC30D-Q100J pinout, 74HC30D-Q100J application, or 74HC30D-Q100J equivalent, key selection criteria include input voltage compatibility (CMOS vs. TTL), propagation delay across temperature and supply voltage, output drive strength (±4 mA at 4.5 V), latch-up immunity (>100 mA), and automotive qualification status.

Technical Context

This device implements a single 8-input NAND logic function with true output polarity and no internal inversion beyond the gate function. All eight inputs feature integrated clamp diodes to GND and VCC, allowing safe interface with signals exceeding supply rails when used with current-limiting resistors.

It operates in standard CMOS logic family behavior: VIH ≥ 70% VCC and VIL ≤ 30% VCC across 2.0–6.0 V, supports rail-to-rail output swing, and exhibits low static ICC (≤40 μA at 6.0 V, −40 °C to +125 °C) and dynamic CPD of 15 pF for accurate power estimation.

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. However, sustained operation above VCC requires external current-limiting resistors to restrict IIK to ±20 mA per pin, as specified in Table 4. Exceeding this current risks permanent damage.

Can 74HC30D-Q100J drive a 50 pF load at 10 MHz without signal degradation?

Yes - with tpd = 26 ns and tt = 15 ns at VCC = 4.5 V, CL = 50 pF, the gate comfortably supports 10 MHz toggle rates. Dynamic power is calculable via PD = CPD × VCC² × fi × N = 15 pF × (4.5 V)² × 10 MHz × 8 = ~24 mW, well below the 500 mW Ptot limit at 25 °C.

How does the latch-up immunity specification impact PCB layout?

Latch-up immunity >100 mA per JESD78 Class II Level B means the device withstands transient currents up to that level without entering destructive thyristor conduction. Layout must still minimize ground bounce and supply rail collapse - use dedicated GND plane, local 100 nF ceramic decoupling at Pin 7, and avoid shared return paths with high-current solenoids or motors.

Is there a recommended minimum trace length between VCC and GND pins for optimal noise rejection?

Yes - keep the VCC (Pin 14) to GND (Pin 7) loop area under 25 mm². Place a 100 nF X7R ceramic capacitor with shortest possible traces (≤2 mm total length) directly between these pins. This minimizes high-frequency impedance and suppresses supply-induced crosstalk into the 8-input logic array.
