Quad 2-input EXCLUSIVE-NOR gate 74HC7266
FEATURES
•Output capability: standard
•ICC category: SSI
GENERAL DESCRIPTION
The 74HC7266 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL).
They are specified in compliance with JEDEC standard no. 7A.
The 74HC7266 provide the EXCLUSIVE-NOR function with active push-pull output.
QUICK REFERENCE DATA
GND = 0 V; Tamb =25°C; tr=t
f= 6 ns
Notes
1. CPD is used to determine the dynamic power dissipation (PD in µW):
PD=C
PD × VCC2× fi+∑ (CL×VCC2×fo) where:
fi= input frequency in MHz
fo= output frequency in MHz
CL= output load capacitance in pF
VCC = supply voltage in V
∑ (CL×VCC2×fo) = sum of outputs
2. For HC the condition is VI= GND to VCC
For HCT the condition is VI= GND to VCC − 1.5 V
