74C, 74H, 74HC, 74HCT, 74F, 74S Logic IC's

74C, 74H, 74HC, 74HCT, 74F,  74S Logic IC's

The 74C, 74F, 74H, 74HC, and 74S logic IC families are similar in function to the original 7400 series TTL family. Each of these families has particular features and specifications, as follows:

74C: These are CMOS designs that are electrically similar to the 4000 series IC's, but with 74 series functionality. Their operating range is 4-15 VDC. They are static sensitive and are not particularly robust devices.

74H: These are high speed with 6 ns gate propogation time. Their power dissipation is 22 mw. They were superseded by the 74S series.

74HC: These are high speed CMOS designs with performance that is similar to the 74LS series. Gate propogation time is 12 ns. Their operating range is 2-6 VDC.

74HCT: These are also high speed CMOS designs, but their logic levels are compatible with bipolar components.

74F: These are fast IC's that were introduced by Fairchild in 1978. Gate propogation time is 3.4 ns, dissipation is 6 mw. Their operating range is 4.5–5.5 VDC.

74S: This is a high-speed Schottky series with diode clamps at the inputs to prevent charge storage. Operation is faster than the 74 and 74H series, but with increased power consumption and cost. Gate propogation time is 3 ns, dissipation is 20 mw.

Most of these devices are now discontinued. All the items in these listings are standard DIP IC's. Most packages are 14 and 16 pins, but some devices are larger.

• Most of these listings have no individual photos, but do indicate package type. In almost all cases our generic part number will be enough to match the part you need, but to confirm a correct match, click on the listing and check the package type in Overview section.

• About 90% of these items are from major manufacturers like Texas Instruments, Motorola, Dallas, Fairchild, Hitachi, National, NEC, etc., but some are unbranded or from minor manufacturers. All parts are unused and fully guaranteed. Some older parts show age from long-term storage, but this will not affect proper operation. None of our parts are counterfeit or B stock.

• You can always use the search box to find a specific part, but it's best to use the basic, generic part number, with no prefix or suffix.

• If you can’t find what you need, please ask. Contact us.
