XC74WL125ASR is Dual Bus 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.
