Product details

5V TTL bus buffer — why the 74HCT family still matters

The CD74HCT541M: The 3-state output control lets you tie multiple buffers onto a shared data bus without contention. Single-element architecture means all eight bits are controlled by one output-enable pin.

This is a mature 74HCT part — the series has been around for decades — but active means you can still book factory orders through standard distribution without a last-time-buy deadline. For BOM planning, there is no urgency to qualify a second source today, but given the age of the HCT family, it is worth watching for PCN notifications on wafer fab changes or package material shifts that could affect long-term supply. ROHS3 compliant, so no exemption expiry to track for EU markets.

Frequently asked questions

What is the difference between CD74HCT541M and CD74HC541M?

Both are 8-bit non-inverting buffers in the same package and pinout, but the HCT version (this part) is specified for TTL-compatible input thresholds — it guarantees a logic-low input at 0.8V and logic-high at 2.0V, matching 5V TTL logic families. The HC version uses CMOS thresholds (0.3 x VCC and 0.7 x VCC). If your driving device is a 5V TTL output (like a 74LS or 74ALS gate), the HCT variant gives cleaner noise margin. If the driver is another CMOS device running at 5V, either works, but HC typically draws lower quiescent current.
