XC74WL34AASR is Triple Buffer manufactured using silicon gate CMOS
processes. The small quiescent 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.
