CD54HC27, CD74HC27, CD54HCT27, CD74HCT27 Data sheet acquired from Harris Semiconductor SCHS132C August 1997 - Revised September 2003 High-Speed CMOS Logic Triple 3-Input NOR Gate Description The ’HC27 and ’HCT27 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.
