Philips Semiconductors
Triple 3-input OR gate
Product specification
74HC/HCT4075
FEATURES
• Output capability: standard
• I_CC category: SSI
GENERAL DESCRIPTION
The 74HC/HCT4075 are high-speed Si-gate CMOS
devices and are pin compatible with the “4075” of the
“4000B” series. They are specified in compliance with
JEDEC standard no. 7A.
The 74HC/HCT4075 provide the 3-input OR function.

Notes
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 × V_CC2 × f_o) = sum of outputs
C_L = output load capacitance in pF
V_CC = supply voltage in V
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
