Overview
The NXP USA Inc. 74HCT30N,652 is an 8-input NAND gate belonging to the HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features TTL-level input compatibility and includes input clamp diodes for interfacing with voltages exceeding VCC. Static characteristics specify a maximum propagation delay of 42 ns at 4.5 V with a 50 pF load.
Feature Summary
- Provides eight-input NAND logic functionality compatible with TTL levels
- Includes input clamp diodes to allow current limiting resistors for high-voltage interfacing
- Offers high noise immunity and low power CMOS dissipation
- Features robust ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)
Applications
- Digital logic circuits requiring multi-input NAND operations
- Systems interfacing TTL outputs with CMOS inputs
- General-purpose digital signal processing applications
Procurement Notes
Verify the specific package type against ordering information, as the datasheet lists SO14 and TSSOP14 variants but does not explicitly confirm PDIP availability for this suffix. Confirm the manufacturer origin, noting that Nexperia products are often distributed under the NXP brand name. Ensure the component meets the required temperature range specifications for the intended operating environment.
Selection Notes
Select this component when an 8-input NAND gate with TTL-compatible inputs is required in a CMOS system. The HCT series ensures direct interface with standard TTL logic without level shifting. Consider the propagation delay limits and power dissipation requirements relative to the system clock speed and thermal constraints.
Part Context
This component is part of the 74HCT30 series manufactured by Nexperia. The 'N' suffix typically denotes a through-hole package variant, although the provided datasheet primarily details surface-mount packages (SO14 and TSSOP14). The HCT logic family bridges the gap between older TTL standards and modern CMOS technology.
FAQ
Does the 74HCT30N,652 have Schmitt trigger inputs?
No, the functional description and pin configuration do not indicate Schmitt trigger inputs; it utilizes standard CMOS/TTL input structures.
What is the function of the input clamp diodes?
The input clamp diodes enable the use of current-limiting resistors to interface inputs to voltages in excess of VCC safely.
