XC74WL74AASR

ETR1318_001

CMOS Logic

■GENERAL DESCRIPTION

XC74WL74AASR is d-type flip flop manufactured using silicon gate CMOS processes. The small supply current, which is one

of the features of the CMOS logic, gives way to high speed operations which enables LS-TTL.

With wave forming buffers connected internally, stabilized output can be achieved as the series offers high noise immunity.

As the series is integrated into a mini molded, MSOP-8B package, high density mounting is possible.
