Frequently asked questions

What is the function of CD74HCT74MT and its clock frequency?

Maximum clock frequency is 50 MHz.

What is the maximum clock frequency of CD74HCT74MT?

50 MHz.

Is CD74HCT74MT equivalent to SN74HCT74?

The CD74HCT74MT and SN74HCT74 are both 74HCT dual D-type flip-flops with set/reset in a 14-pin SOIC package, functionally equivalent. The CD prefix is Texas Instruments; the SN prefix was used by the same fab. Pin-for-pin compatible.

What is the difference between 74HC74 and 74HCT74?

The 74HCT74 has TTL-compatible input thresholds (0.8 V / 2.0 V) and is a direct drop-in for 5 V TTL systems. The 74HC74 uses CMOS-level thresholds (typically 0.3×VCC / 0.7×VCC). Both run at 50 MHz. If you are replacing a 74LS or 74S part, use the HCT variant so the inputs see the correct logic levels.
