74HC00D

Overview

The Toshiba 74HC00D is a high-speed CMOS quad 2-input NAND gate fabricated with silicon gate C2MOS technology. It operates within a supply voltage range of 2.0 to 6.0 V and supports an operating temperature from -40°C to +125°C. Typical propagation delay is 6 ns at 5 V, with balanced tPLH and tPHL. Quiescent current is typically 1.0 µA at 25°C. The device provides 5.2 mA output drive capability and includes input protection against static discharge.

Feature Summary

• High-speed operation comparable to LSTTL while maintaining low power consumption
• Internal three-stage circuit design ensures stable output and high noise immunity
• Input pins feature built-in protection circuits for static discharge and transient voltage

Applications

• General digital logic processing
• Signal gating and switching applications
• Data routing in electronic systems

Procurement Notes

Verify the specific ordering suffix and package variant (SOIC-14) against the manufacturer's latest documentation before procurement. Confirm RoHS compliance status directly with the supplier or via official datasheets, as environmental declarations may vary by production batch. Ensure the component meets the required operating temperature range for the intended application environment.

Selection Notes

Select this component when a standard quad NAND function is required with CMOS compatibility. It serves as a suitable replacement for older logic families where lower power dissipation is needed without sacrificing significant speed. Verify that the 2V to 6V supply range aligns with the system's power architecture and that the SOIC-14 footprint fits the PCB layout constraints.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices produced by Toshiba Semiconductor and Storage. The 74HC00D specifically implements the standard quad 2-input NAND logic function. It is designed for general-purpose digital applications requiring reliable switching performance across a wide voltage and temperature range.

Replacement Considerations

Check for equivalent parts from other manufacturers offering the same 74HC00 logic function in an SOIC-14 package. Ensure pinout compatibility and verify that electrical characteristics such as propagation delay and output drive current meet or exceed the requirements of the original design.
