M74HC266 datasheet

 

Description :

The M74HC266 is an high speed CMOS QUAD EXCLUSIVE NOR GATE fabricated with silicon gate C
2MOS technology. The M74HC266 has a high performance N-channel MOS transistor (OPEN DRAIN output). Input and Output ensure high noise immunity and stable outputs.

Features

1. HIGH SPEED : tPD = 10ns (TYP.) at VCC = 6V
2. LOW POWER DISSIPATION :  ICC = 1mA(MAX.) at TA=25°C
3. HIGH NOISE IMMUNITY : VNIH = VNIL = 28 % VCC (MIN.)
4. WIDE OPERATING VOLTAGE RANGE : VCC (OPR) = 2V to 6V
5. PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 266
