74LCX08MTCX Quad 2-Input AND Gate IC – TSSOP-14

Description

The 74LCX08MTCX is a high-performance, low-voltage Quad 2-Input AND gate designed for modern digital systems. It belongs to the LCX (Low-Voltage CMOS) family, which is specifically engineered to operate in 3.3V systems while offering critical 5V tolerance on its inputs. This feature makes it an invaluable tool for level-shifting, allowing seamless communication between older 5V logic families and newer, low-voltage 3.3V microcontrollers or processors.

The device is built to handle high-speed requirements with a propagation delay (tPD) of only 5.5ns at 3.3V. Furthermore, it incorporates power-down high-impedance technology, ensuring that inputs and outputs remain in a high-impedance state when the power is removed, preventing signal contention or current leakage in multi-voltage system environments.

Note: Product images are for illustrative purposes only. Please refer to the official datasheet for detailed propagation delay characteristics, input/output voltage thresholds, and recommended decoupling capacitor values for your high-speed logic circuits.

Features

• 5V Tolerant Inputs: Enables direct interfacing between 5V-logic and 3.3V-logic systems without additional level shifters.
• High-Speed Logic: Low propagation delay of 5.5ns (max) at 3.3V VCC.
• Low Power Consumption: Extremely low quiescent current (ICC = 10µA max).
• Power-Down Protection: Inputs and outputs maintain high-impedance states during power-down conditions.
• Robust Construction: Latch-up performance exceeds JEDEC 78 standards, ensuring high operational reliability.
• Package: Compact 14-pin TSSOP surface-mount (SMD) package.

Benefits

• Level Translation: Simplifies designs by removing the need for external level-shifting circuitry in mixed-voltage projects.
• System Safety: Power-down high-impedance protection prevents accidental damage or interference when parts of a system are powered off.
