Product details

Package and mounting

The 20-lead CDIP (0.300-inch body width, 7.62 mm) is a through-hole ceramic package. It requires a socket or soldered through-hole on the PCB — no surface-mount option exists for this order code. The hermetic ceramic construction is the reason this part is chosen over a plastic SOIC or TSSOP: it survives moisture, outgassing, and thermal cycling that would crack a plastic package. If your board is all SMT, this part forces a mixed-technology assembly step.

Lifecycle and compliance

It is RoHS non-compliant, meaning it contains lead (Pb) in the solder finish or die-attach. For designs that must meet EU RoHS or similar regulations, this part is not an option unless an exemption applies (e.g., military/aerospace). For non-RoHS projects, the active status is a green light for new designs and volume procurement.

Frequently asked questions

Is 54FCT244TDB RoHS compliant?

No, 54FCT244TDB is RoHS non-compliant. It contains lead and is not suitable for RoHS-required assemblies unless an exemption applies.

What is the difference between 54FCT244TDB and 74FCT244TDB?

The 54 prefix denotes a military-temperature-range device (-55°C to 125°C), while the 74 prefix typically covers the commercial/industrial range (0°C to 70°C or -40°C to 85°C). The 54FCT244TDB also uses a hermetic ceramic package (CDIP) versus the plastic DIP or SOIC of the 74 series. Function and pinout are generally the same, but the 54-grade part is specified for high-reliability environments.
