Quad 2-input EXCLUSIVE-NOR gate
Product specification
74HC7266
FEATURES
• Output capability: standard
• I_CC 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.

note 1
1. C_PD is used to determine the dynamic power dissipation (P_D in µW):
P_D = C_PD × V_CC2 × f_i +∑ (C_L × V_CC2 × f_o) where:
f_i = input frequency in MHz
f_o = output frequency in MHz
C_L = output load capacitance in pF
V_CC = supply voltage in V
∑ (C_L × V_CC2 × f_o) = sum of outputs
2. For HC the condition is V_I = GND to V_CC
For HCT the condition is V_I = GND to V_CC − 1.5 V
