74HCT00PW,112

Overview

The 74HCT00PW,112 is a quad 2-input NAND gate from the Nexperia 74HCT series. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range of -40 °C to +125 °C. The device features TTL-compatible input levels and includes clamp diodes on inputs for interfacing with voltages exceeding VCC. It utilizes a TSSOP14 (SOT402-1) package with a body width of 4.4 mm. Static characteristics specify a maximum low-level output voltage of 0.4 V at 4 mA load and a high-level output voltage of 3.7 V at -4 mA load under recommended conditions.

Feature Summary

• Quad configuration providing four independent 2-input NAND logic gates in a single integrated circuit.
• TTL-compatible input voltage levels ensure direct interface compatibility with standard digital logic families.
• Integrated input clamp diodes allow safe interfacing with current-limiting resistors for voltages higher than the supply rail.
• High noise immunity and robust latch-up performance compliant with JESD 78 Class II Level B standards.

Applications

• General-purpose digital logic signal processing
• Interface circuits requiring TTL-to-CMOS level translation
• Data routing and selection logic in embedded systems

Procurement Notes

Verify the specific ordering suffix ',112' corresponds to the TSSOP14 package variant when sourcing. Confirm that the component meets the required RoHS compliance status as indicated in the product data sheet. Ensure design specifications align with the absolute maximum ratings to prevent permanent damage during operation or storage.

Selection Notes

Select this component when a quad NAND gate with TTL-compatible inputs is required for 5 V logic applications. The TSSOP14 package offers a compact surface-mount solution suitable for space-constrained designs. Consider the specified operating temperature range and power dissipation limits relative to the intended thermal environment and load conditions.

Part Context

This part belongs to the 74HCT family of CMOS logic devices manufactured by Nexperia. The 'HCT' designation indicates High-speed CMOS technology with TTL-compatible inputs, bridging the gap between older TTL standards and modern CMOS efficiency. The PW suffix specifically denotes the Thin Shrink Small Outline Package (TSSOP), distinguishing it from other package options like SO or DHVQFN.

Replacement Considerations

Cross-reference with other 74HCT00 variants in different packages such as 74HCT00D (SO14) if pinout compatibility allows. Verify functional equivalence with other manufacturers' 74HCT00 parts, ensuring matching input/output electrical characteristics and package dimensions for direct replacement.

FAQ

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, protecting the internal circuitry from overvoltage conditions.

Does the 74HCT00PW support voltages above 5.5 V?

No, the recommended operating conditions specify a maximum supply voltage (VCC) of 5.5 V for the 74HCT00 variant. Exceeding this limit may violate absolute maximum ratings.
