DESCRIPTION
The M54/74HC266/7266 are high speed CMOS
QUADEXCLUSIVE NORGATES, fabricatedin silicon gate C2MOS technology. They have the same
high speed performance of LSTTL combined with
true CMOS low power consumption.
The HC266 has a high performance N-channel
MOS transistor (OPENDRAIN output).
The HC7266 has an output buffer which is CMOS
structure.
Inputand outputbuffersensure highnoiseimmunity
and stableoutputs.
All inputs are equipped with protection circuits
against static discharge and transient excess voltage.
