CD74HCT03MT

Inverter Gates Overview

The CD74HCT03MT is a high-speed CMOS logic device manufactured by Texas Instruments, featuring four independent 2-input NAND gates with open-drain outputs. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -55°C to +125°C. The component utilizes a 14-pin Small Outline Integrated Circuit (SOIC) package with a width of 0.154 inches (3.90 mm). Designed for surface-mount technology, it belongs to the HCT logic series, ensuring compatibility with TTL-driven interfaces while maintaining low power consumption typical of CMOS technology.

Inverter Gates Feature Summary

• Integrates four independent 2-input NAND logic functions within a single compact package

• Interface circuits between different voltage domains
• General-purpose switching and signal gating in embedded systems

Inverter Gates Procurement Notes

Verify the specific suffix 'M96' or 'MT' against the manufacturer's current datasheet to confirm package dimensions and tape-and-reel specifications. Ensure that the open-drain nature of the outputs is accounted for in the circuit design, as pull-up resistors are required for proper high-state logic levels. Confirm RoHS compliance status and lead-free material declarations if required by your manufacturing standards.

Inverter Gates Selection Notes

Select this component when open-drain NAND logic is required for bus sharing or voltage translation tasks. The HCT series ensures compatibility with TTL input thresholds, making it suitable for interfacing with legacy digital components. Consider the SOIC package size for PCB layout constraints and verify that the maximum output current capabilities meet the load requirements of the connected circuitry.

Inverter Gates Part Context

This device is part of Texas Instruments' extensive 74HCT logic family, which bridges the gap between HC CMOS speed and HCT TTL compatibility. The CD74HCT03 variant specifically provides quad 2-input NAND gates with open-drain outputs, distinguishing it from standard push-pull output variants like the CD74HC03. This family is widely used in general-purpose digital electronics for its balance of speed, power efficiency, and noise immunity.

Inverter Gates Replacement Considerations

Direct pin-compatible alternatives include the CD74HC03MT for push-pull outputs or other manufacturers' equivalents such as SN74HCT03N. Verify electrical characteristics, particularly propagation delay and output drive strength, before substitution. Ensure that any replacement maintains the open-drain output requirement if the original application relies on this feature.
