onsemi 20-SOIC 74ACTQ373SCX

The 74ACTQ373SCX is a high-speed CMOS-based octal D-type transparent latch with three-state outputs, manufactured by Fairchild (now part of ON Semiconductor). It's designed for low power consumption and improved noise immunity compared to its TTL counterparts like the 74LS373. The device features an enable input (G) and a latch enable input (LE) to control data transfer and output latching. Commonly used in memory addressing applications, it buffers and locks address signals or general-purpose data, presenting a high-impedance state when not enabled. This part number suggests an advanced package or specific manufacturer's variant optimized for performance in demanding digital circuits.
