74V1G04CTR

74V1G04CTR Description

The 74V1G04CTR is a single-channel CMOS inverter from STMicroelectronics, part of the 74V series, designed for high-speed digital logic applications. Operating within a 2V to 5.5V supply range, it delivers a maximum propagation delay of 7.5ns at 5V with a 50pF load, ensuring efficient signal inversion in low-power systems. Packaged in a compact SOT323-5 surface-mount form factor, this device is ideal for space-constrained designs. Although marked as obsolete, it remains a reliable choice for legacy systems due to its low quiescent current (1µA max) and RoHS3 compliance, meeting modern environmental standards.
