TC74HC670AF - 4 WORD x 4-BIT REGISTER FILE
TC74HC670AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC670AP, TC74HC670AF 4 Word × 4 Bit Register File (3-state) The TC74HC670A is a high speed 4-WORDS × 4-BITS REGISTER FILE fabricated with silicon gate C2MOS technology.
It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.
The register file is organized as 4 words of 4 bits each.
Separate read and write address inputs (RA, RB, and WA, WB) and enable inputs (
