CD74HCT20EG4

Inverter Gates Overview

The CD74HCT20EG4 is a high-speed CMOS logic device manufactured by Texas Instruments, featuring two independent four-input NAND gates. It operates within a supply voltage range of 4.5 V to 5.5 V and supports propagation delays as low as 28 ns at 5 V. The component utilizes a 14-pin plastic dual in-line package (PDIP) with industrial temperature ratings spanning from -55 °C to +125 °C.

Inverter Gates Feature Summary

• Provides two independent four-input NAND logic functions within a single integrated circuit
• Compatible with standard TTL logic input levels due to HCT series architecture
• Supports wide operating temperature ranges suitable for industrial applications

Inverter Gates Applications

• Digital logic control circuits requiring multi-input NAND operations
• Industrial automation systems utilizing high-speed CMOS logic families
• General-purpose digital signal processing and data routing applications

Inverter Gates Procurement Notes

Verify the specific suffix 'EG4' against official manufacturer documentation to confirm compliance with RoHS directives and material composition requirements. Ensure that the procurement channel sources components directly from authorized distributors or the manufacturer to guarantee authenticity and traceability. Cross-reference the datasheet revision history to confirm current manufacturing status and any potential design changes affecting pinout or electrical characteristics.

Inverter Gates Selection Notes

Select this component when designing circuits that require multiple four-input NAND gates within a single package footprint. The HCT series ensures compatibility with standard 5 V TTL logic interfaces, simplifying integration with legacy digital systems. Consider the PDIP-14 package constraints for through-hole mounting requirements and verify that the 28 ns propagation delay meets the timing specifications of the target application's clock speeds.

Inverter Gates Part Context

This part belongs to the Texas Instruments 74HCT logic family, which bridges the performance gap between standard 74HC CMOS and 74LS TTL technologies. The 'E' designation indicates a plastic DIP package, while 'G4' typically signifies lead-free and RoHS-compliant manufacturing processes. This family is widely used in embedded systems where noise immunity and power efficiency are critical alongside standard logic level interfacing.

Inverter Gates Replacement Considerations

Consult official substitution guides for equivalent parts such as the CD74HCT20E or other industry-standard 74HCT20 variants. Verify pin-to-pin compatibility and electrical parameter alignment before implementing any alternative components in existing designs.
