Renesas Electronics Corporation 20-SOIC 74FCT621TSOG8

The 74FCT621TSOG8 is an 8-bit tri-state bus transceiver from Fairchild/ON Semiconductor, designed for high-speed operation in Fast CMOS technology. This device features individual output enable (OE) control and dual directional data flow, allowing it to function as a bidirectional buffer on an 8-bit bus. It is pin-compatible with the standard 74 series logic and provides low power consumption with high noise immunity. The 'TSOG8' package suggests it uses a small-outline TSSOP package, suitable for space-constrained designs requiring high-speed data transfer.
