■GENERAL DESCRIPTION
XC74WL125ASR is dual bus buffer 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.
■PIN CONFIGURATION
■FEATURES
High Speed Operations : tpd = 3.8ns(TYP.) (VCC=5V)
Operating Voltage Range : 2V ~ 5.5V
Low Power Consumption : 2μA (MAX.)
CMOS Logic Dual Bus Buffer
Small Package : MSOP-8B
