FEATURES
•Output capability: standard •I CC category: SSI GENERAL DESCRIPTION
The 74HCU04 is a high-speed Si-gate CMOS device and is pin compatible with low power Schottky TTL (LSTTL).It is specified in compliance with JEDEC standard no. 7A.
The 74HCU04 is a general purpose hex inverter. Each of the six inverters is a single stage QUICK REFERENCE DATA
GND =0V; T amb =25°C; t r =t f =6ns
Note
1.C PD is used to determine the dynamic power dissipation (P D in µW):
P D =C PD ×V CC 2×f i + ∑(C L ×V CC 2×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 CC 2×f o )=sum of outputs ORDERING INFORMATION
