WITH 54/74LS7266

The M54/74HC266/7266 are high speed CMOS

QUAD EXCLUSIVE NOR GATES, fabricated in sili-

con gate C

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.
