MM74HCT05MTCX

Inverter Gates Overview

The MM74HCT05MTCX is an octal buffer and line driver manufactured by onsemi, belonging to the 74HCT logic series. It features eight non-inverting outputs with open-drain configuration, designed for high-drive capability in bus-oriented systems. The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a TSSOP-20 surface-mount package. Key electrical characteristics include a propagation delay of 33 ns at 5 V, static current of 8 µA, and output drive capabilities of -7.2 mA (high) and 7.2 mA (low). It supports an operating temperature range from -40 °C to +85 °C.

Inverter Gates Feature Summary

• Octal buffer architecture providing eight independent non-inverting channels for parallel data transmission.
• Open-drain output structure enabling direct interfacing with higher voltage buses and wired-OR logic configurations.
• High-current drive capability suitable for driving capacitive loads and long transmission lines.
• CMOS technology ensuring low static power consumption while maintaining compatibility with TTL input levels.

Inverter Gates Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffering for timing signals
• Transceiver circuits requiring level shifting or isolation
• Control signal distribution in industrial automation systems

Inverter Gates Procurement Notes

Verify the specific suffix 'MTCX' corresponds to the TSSOP-20 package and reel packaging format as documented. Confirm RoHS compliance status through official manufacturer declarations prior to integration. Ensure ESD handling procedures are followed during assembly due to CMOS sensitivity. Cross-reference the datasheet revision date to validate parameter accuracy against current production standards.

Inverter Gates Selection Notes

Select this component when an octal buffer with open-drain outputs is required for bus applications. The HCT series ensures compatibility with standard 5 V TTL logic families. Consider the TSSOP-20 package for space-constrained PCB layouts. Verify that the open-drain nature aligns with system pull-up requirements and voltage levels.

Inverter Gates Part Context

This part belongs to the MM74HCTxx family of high-speed CMOS logic devices produced by onsemi. The 74HCT series bridges the performance gap between older TTL logic and modern CMOS technologies, offering faster switching speeds than standard 74HC devices while maintaining TTL-compatible input thresholds. The MM74HCT05 specifically provides open-drain outputs distinct from the push-pull outputs found in variants like the MM74HCT541.
