DESCRIPTION:
The IDT39C02A is a high-speed carry lookahead generator built using advanced CEMOS'" II, a dual metal 1.5p.m CMOS technology. The IDT39C02A is generally used with an arithmetic logic unit to provide high-speed lookahead over larger word lengths.
The IDT39C02A is a pin-compatible, performance enhanced, functional replacement for al...
