GENERAL DESCRIPTION
74HC/HCT32
The 74HC/HCT32 are high-speed Si-gate CMOS devicesand are pin compatible with low power Schottky TTL(LSTTL). They are specified in compliance with JEDECstandard no. 7A.
The 74HC/HCT32 provide the 2-input OR function.
QUICK REFERENCE DATA

SYMBOLtPHL/ tPLHCICPDNotes
1.CPD is used to determine the dynamic power dissipation (PD inμW):
PD=CPD×VCC2×fi+∑(CL×VCC2×fo) where:fi=input frequency in MHzfo=output frequency in MHz
∑(CL×VCC2×fo)=sum of outputsCL=output load capacitance in pFVCC=supply voltage in V
2.For HCthe condition is VI=GND to VCC
For HCT the condition is VI=GND to VCC?1.5VORDERING INFORMATION
