CMOS Logic ◆CMOS Logic Triple Schmit Inverter ■Applications ◆Operating Voltage Range : 2V ~ 5.5V ●Palmtops ◆High Speed Operations ●Digital Equipment : tpd =2.3ns TYP ◆Low Power Consumption : 1µA (max) ◆MSOP-8B Package ■Description ■Features XC74WL14AASR is Triple Schmit Inverter 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.
