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

GND=0V; Tamb=25°C; tr=tf=6ns

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
