Texas Instruments 20-SOIC SN74AHCT244QDWRG4

The SN74AHCT244QDWRG4 is a quadruple 3-state bus buffer and driver from Texas Instruments' 74AHCT series. It consists of two 4-bit buffers with individual output enables (OE). When OE\ is low, it transparently transfers data from the A inputs to the Y outputs; when OE\ is high, the outputs enter a high-impedance state. This device is designed for improved performance and density in applications such as memory address drivers and bus-oriented receivers. Packaged in a small QFN Green package (GDWRG4), it operates over a wide voltage range, typically 4.5V to 5.5V, and offers enhanced power savings compared to standard TTL parts.
