What are the key features of CD74HCT00E-NG?
- Quad 2-input NAND gate with TTL-compatible input thresholds allows direct interfacing with 5 V TTL and LSTTL logic in the HCT family
- High-speed CMOS switching with typical propagation delay below 10 ns at 5 V enables use in clock gating and combinational logic circuits
- 14-pin DIP package ideal for through-hole breadboard prototyping, educational labs, and legacy board repair with standard 2.54 mm pin pitch
What is CD74HCT00E-NG used for?
The CD74HCT00E-NG is a fundamental building block for digital logic design, used in clock gating, signal inversion chains, SR latch construction, and logic level conversion from TTL to CMOS systems. Its HCT-family TTL-compatible inputs make it interchangeable with older LSTTL NAND gate designs while providing full CMOS rail-to-rail output voltage swing on a 5 V supply. Educational electronics labs, hobbyist prototyping boards, and legacy industrial control panel repairs frequently use this 14-pin DIP device due to its through-hole convenience.

Frequently Asked Questions
What supply voltage range does the CD74HCT00E-NG require and how many NAND gates does it contain?
The CD74HCT00E-NG operates from 4.5 V to 5.5 V and contains 4 independent 2-input NAND gates in a single 14-pin DIP package, each gate capable of driving standard CMOS and TTL loads with propagation delays under 15 ns at 5 V.
Can the CD74HCT00E-NG interface directly with older TTL or LSTTL logic families without level-shifting?
Yes; HCT-family devices use TTL-compatible input thresholds of approximately 0.8 V for logic low and 2 V for logic high, allowing direct connection to 74LS, 74S, and similar TTL families operating at 5 V without any additional level-shifting circuitry.
For a breadboard SR latch implementation, how would the CD74HCT00E-NG be used and what timing should be expected?
Two of the 4 NAND gates in the CD74HCT00E-NG can form a cross-coupled SR latch; with a 5 V supply, the set-reset propagation delay from input to stable output is typically under 10 ns, providing reliable 100 MHz-class latch switching suitable for debouncing buttons and capturing single-edge events in digital circuits.
