Nexperia USA Inc. 74HC30D,652

Overview

74HC30D,652 from Nexperia is an 8-input CMOS NAND gate in SO14 package, operating from 2.0 V to 6.0 V supply, delivering typical propagation delay of 15 ns at 4.5 V/50 pF, with ±25 mA output drive capability and input clamp diodes enabling overvoltage-tolerant interfacing in industrial control logic arrays.

For engineers reviewing the 74HC30D,652 datasheet, 74HC30D,652 pinout, 74HC30D,652 application, or 74HC30D,652 equivalent, this device supports high-noise-immunity combinational logic in space-constrained PCBs requiring TTL-compatible (74HCT30) or CMOS-level (74HC30) input thresholds, stable operation from –40 °C to +125 °C, and JEDEC-compliant ESD robustness.

Technical Context

This device implements a single 8-input NAND function using standard CMOS transistor topology, with inputs featuring integrated clamp diodes for current-limited overvoltage tolerance up to ±20 mA per pin. Its static VIH/VIL thresholds are supply-dependent: at VCC = 4.5 V, VIH ≥ 3.15 V (74HC30) and VIL ≤ 1.35 V.

Dynamic behavior is characterized by propagation delays (tpd) ranging from 12 ns (VCC = 6.0 V) to 130 ns (VCC = 2.0 V) under CL = 50 pF load, and transition times (tt) as low as 6 ns at 6.0 V. Power dissipation capacitance CPD is fixed at 15 pF, enabling accurate dynamic power estimation via PD = CPD × VCC² × fi × N.

FAQ

What is the maximum clock frequency supported by the 74HC30D,652?

The 74HC30D,652 is a combinational logic gate-not a clocked device-so it has no defined clock frequency. Its usable toggle rate depends on propagation delay and load: with tpd = 15 ns (typical at 4.5 V/50 pF), maximum reliable data rate is ~33 MHz for clean square-wave input patterns. Higher rates risk pulse distortion due to finite transition times (tt = 7 ns).

Can 74HC30D,652 inputs be left floating?

No. All eight inputs (Pins 1, 2, 3, 4, 5, 6, 11, 12) must be actively driven HIGH or LOW; floating inputs cause undefined output states, increased ICC current, and potential oscillation due to CMOS input stage metastability. Use pull-up or pull-down resistors (typically 10–100 kΩ) if signals are inactive.

Does 74HC30D,652 support mixed-voltage operation (e.g., 3.3 V inputs with 5 V VCC)?

Yes-within limits. With VCC = 5 V, VIH(min) = 3.15 V (74HC30), so 3.3 V CMOS outputs meet threshold. However, inputs must not exceed VCC + 0.5 V (5.5 V). The integrated clamp diodes allow safe 3.3 V inputs at 5 V VCC, but avoid sustained >5.5 V at any pin.

How does thermal derating affect power dissipation in SO14 package?

For SOT108-1 (SO14), Ptot = 500 mW at ≤100 °C, then derates linearly at 10.1 mW/K above 100 °C. At +125 °C ambient, max allowable power drops to 475 mW. This reflects junction-to-air thermal resistance (RθJA ≈ 100 K/W); ensure adequate copper area and airflow to maintain TJ < 150 °C.
