Features  
Description  
• Buffered Inputs  
The ’HC21 and CD74HCT21 logic gates utilize silicon gate  
CMOS technology to achieve operating speeds similar to  
LSTTL gates with the low power consumption of standard  
CMOS integrated circuits. All devices have the ability to drive  
10 LSTTL loads. The HCT logic family is functionally pin  
compatible with the standard LS logic family.  
• Typical Propagation Delay: 9ns at V
