DESCRIPTION
The M54/74HC266/7266 are high speed CMOS
QUAD EXCLUSIVE NOR GATES, fabricated in sili-
2
con gate C MOS 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 (OPEN DRAIN output).
The HC7266 has an output buffer which is CMOS
structure.
Input and output buffers ensure high noise immunity
and stable outputs.
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.
