SN74LVC1G18DCKR – TEXAS INSTRUMENTS

The SN74LVC1G18DCKR is a single, low-voltage CMOS quad 2-input OR gate from Texas Instruments, packaged in a space-saving WCSP-6 (6-pin wafer chip scale package). Operating from a wide voltage range of 1.65V to 5.5V, it offers exceptional flexibility in mixed-voltage systems. Its low input current (I_I ≤ 1µA) and low propagation delay (t_pd ≤ 7.7ns @ 3V) make it ideal for low-power, high-speed applications. The device features 5V-tolerant inputs, simplifying interfacing with legacy TTL circuitry. Each gate exhibits a low output impedance, ensuring fast switching and reliable signal transmission, even under heavy loading conditions. The Schmitt-trigger input hysteresis (typically 0.4V) enhances noise immunity, crucial in noisy environments. Common applications include simple logic gating in battery-powered devices, embedded systems, and automotive electronics where space and power consumption are critical. Its low power consumption, compared to its 74LS and 74HC counterparts, and its wide voltage tolerance represent key advantages in modern circuit designs demanding both efficiency and robust operation.
