IDT74FCT16V721
DESCRIPTION:
The FCT16V721 20-bit register is built using advanced dual metal CMOS technology. These high speed devices have been designed for use in high speed, synchronous, memory driving applications. A common clock enable allows memory bank select for memory interleaving applications. The signal skew between output pins is typically less than 250ps, giving a high level of predictability to system timing.
