- 14-PDIP through-hole package with 2.54 mm pitch for breadboard prototyping, through-hole assembly, and direct socket-based replacement in legacy systems
- RoHS-compliant Pb-free construction (JESD-609 e4) with 15-year estimated end-of-life, providing long supply-chain horizon for industrial maintenance inventories
Applications
The CD74HC30E is used wherever a single multi-input NAND function needs to be implemented efficiently in 5 V or 3.3 V digital logic designs, such as chip-select decoding, interrupt enable/mask circuits, and combinational address comparators in microprocessor peripherals. Its 8-input structure lets designers implement complex AND-based conditions in one gate, replacing up to three cascaded 2-input gates and saving PCB real estate in industrial control boards, FPGA glue logic, and bus-arbitration circuits. The 14-DIP package also makes it a standard fit for educational electronics labs and retrofit repairs in production equipment where through-hole components remain mandatory.

Frequently Asked Questions
What supply voltage range and propagation delay does CD74HC30E provide for high-speed digital logic designs?
CD74HC30E operates from a 2 V to 6 V supply, covering both 3.3 V and 5 V logic systems. At a 5 V supply with a 50 pF load, the maximum propagation delay is 23 ns and the typical value is approximately 7 ns. At 3.3 V the worst-case delay increases to around 35 ns, which is still fast enough for most address-decode and combinational glue-logic applications running below 10 MHz.
How can a single CD74HC30E replace multiple smaller NAND gates in a chip-select decode circuit?
A CD74HC30E has 8 inputs feeding a single NAND output, which is functionally equivalent to ANDing all 8 address or control bits and then inverting the result. Implementing the same function with 2-input NAND gates would require at least three 74HC00 gates and two stages of propagation delay, totaling over 14 ns of extra delay. CD74HC30E achieves the same decode in one propagation delay stage of 7 ns typical, using only 1 IC and 14 pins rather than 3 ICs and 42 pins.
What output drive capability does CD74HC30E offer, and how many HC CMOS gate inputs can it drive?
CD74HC30E can sink up to 5.2 mA and source up to 5.2 mA, which is sufficient to drive approximately 50 standard HC CMOS inputs (each drawing around 1 µA) or up to 10 LS-TTL inputs. The output is specified into a 50 pF capacitive load; for larger bus capacitances above 200 pF, a buffer or series resistor of 33 Ω to 100 Ω is recommended to limit overshoot and ringing on the output waveform.
Is CD74HC30E suitable for 3.3 V mixed-voltage systems alongside 5 V TTL logic, or does it need level translation?
CD74HC30E in the HC family uses a CMOS-midpoint input threshold of approximately 50% of VCC — roughly 1.65 V at 3.3 V and 2.5 V at 5 V. This means it can accept 3.3 V CMOS outputs cleanly when powered at 3.3 V, but it is NOT directly TTL-compatible at its standard switching threshold. For 5 V TTL outputs driving a 3.3 V-powered CD74HC30E, a level-shifting stage or the HCT variant with fixed 1.5 V switching threshold should be used instead.
What is the long-term supply availability outlook for CD74HC30E, and in what package configurations is it stocked?
CD74HC30E carries an estimated product life (YTEOL) of 15 years, which is among the longest in Texas Instruments' catalog and signals a mature, stable product for long-lifecycle industrial and defense maintenance builds. The primary in-stock configuration is the 14-PDIP through-hole package with 0.3 inch row spacing (7.62 mm), and tube quantities of 25 or 50 are typically available alongside reel quantities of 2500 for higher-volume orders.
