Product details

CD54HCT245F — high-speed CMOS octal bus transceiver

It operates with HCT input-level compatibility, making it a direct drop-in for systems originally designed for LSTTL logic while offering the power savings of CMOS. Typical applications include bus-oriented systems in industrial control, telecommunications, and instrumentation where bidirectional data transfer and bus isolation are required.

What the active lifecycle means for your BOM

An active lifecycle rating means no immediate pressure to qualify a substitute or secure last-time-buy inventory. The CD54HCT245F is not a candidate for the surplus or broker channel as a routine sourcing strategy — standard distributor stock is the appropriate path.

Frequently asked questions

What is the replacement for CD54HCT245F?

No official replacement or successor is listed for the CD54HCT245F. Because it remains active, a replacement is not needed; the part is available through standard sourcing.

Is CD54HCT245F the same as CD74HCT245?

The CD54HCT245F and CD74HCT245 are both high-speed CMOS octal bus transceivers from the same HCT logic family, but the CD54 prefix typically denotes a different temperature grade or qualification level (often military or high-reliability) compared to the commercial CD74 prefix. Verify the temperature range and specification against your design requirements before substituting.
