Nexperia USA Inc. 74HC30D,653

Overview

74HC30D,653 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 (CL = 50 pF), with TTL-compatible input thresholds on the 74HCT30 variant and full industrial temperature range (-40 °C to +125 °C). It serves as a high-density logic combiner in address decoding, enable gating, and bus arbitration circuits.

For engineers reviewing the 74HC30D,653 datasheet, 74HC30D,653 pinout, 74HC30D,653 application, or 74HC30D,653 equivalent, key selection criteria include input voltage compatibility (CMOS vs. TTL), propagation delay across VCC and temperature, output drive capability (±4 mA at 4.5 V), and SO14 thermal derating behavior above 100 °C.

Technical Context

The 74HC30D implements standard positive-logic NAND functionality: output Y is LOW only when all eight inputs (A–H) are HIGH; otherwise, Y is HIGH. Its internal structure includes buffered CMOS stages with input clamp diodes enabling safe interfacing to voltages exceeding VCC via current-limiting resistors.

It operates under JEDEC-compliant conditions (JESD7A for 2.0–6.0 V, JESD8C for 2.7–3.6 V), supports HBM ESD >2000 V and CDM >1000 V, and maintains specified VOH/VOL across -40 °C to +125 °C with VIH = 3.15 V (min) and VIL = 1.35 V (max) at VCC = 4.5 V for the HC version.

FAQ

What is the maximum clock frequency supported by the 74HC30D,653?

The 74HC30D,653 is a combinational logic device, not a clocked circuit, so it has no defined clock frequency. Its usable switching rate depends on propagation delay (15 ns typ at 4.5 V) and load capacitance. For reliable operation with 50 pF load, maximum toggle rate is approximately 20 MHz, assuming equal rise/fall times and adequate supply decoupling.

Can 74HC30D,653 drive a 10 kΩ pull-up resistor directly?

Yes - the 74HC30D,653 output can sink up to 4.0 mA at VCC = 4.5 V while maintaining VOL ≤ 0.26 V. With a 10 kΩ pull-up to 4.5 V, the steady-state current is 0.45 mA, well within spec. However, transition speed will be limited by RC time constant (~50 ns for 10 kΩ × 50 pF), potentially increasing effective propagation delay.

Are pins 9, 10, and 13 internally connected?

No - pins 9, 10, and 13 are explicitly designated as "not connected" (n.c.) in the official Nexperia datasheet. They have no internal bond wires or silicon connections and must remain unconnected in PCB layout. Tying them to GND or VCC is unnecessary and may risk mechanical stress on the die attach.

Does 74HC30D,653 support mixed-voltage operation (e.g., 3.3 V inputs with 5 V VCC)?

No - the 74HC30D,653 is not designed for mixed-voltage operation. Inputs must stay within 0 V to VCC. Applying 3.3 V inputs to a 5 V-powered device is acceptable (since 3.3 V > VIH = 3.15 V), but applying 5 V inputs to a 3.3 V-powered device violates absolute maximum ratings and risks damage. Clamp diodes only protect against brief excursions beyond VCC by ±0.5 V.
