In general HC are the ones to go for if interfacing to other CMOS chips (they take 2 to 6V so are voltage-agnostic). HCT will in general work fine too if your power supply is 5V. If you want a simple 3.3V to 5V level converter you can use an HCT buffer powered at 5V - its input levels of 0.8/2.0V should be happy with 3V3 drive. system August 28, 2012, 9:53am 3 HCT are cheap, reliable, and simple. Even those considering transistor solutions would be advised to look instead at HCT family ICs just for simple interfacing. Even a single channel interface made using transistors is larger in circuit board space, more complex to build, and likely to cost more - especially so if you put a value on time. Fault finding with HCT is ridiculously simple, whereas a transistor format has multiple points for potential faults, and will take much longer to fault find, and to replace a faulty component. "Keep it simple" usually pays well in the long run!! MarkT August 28, 2012, 10:21am 4 ipadwarrior: HCT are cheap, reliable, and simple.
