Product details

What this 4-function D latch is and where it fits

The 4042BDC is a D latch with four independent latch functions, used for temporary data storage in digital logic circuits.

Lifecycle and compliance — active but RoHS non-compliant

The part is RoHS non-compliant, which restricts its use in assemblies that must meet EU RoHS exemption-free requirements.

Sourcing and availability

As an active, RoHS non-compliant part, the 4042BDC is sourced through independent distribution channels and quoted to order against an RFQ.

Frequently asked questions

What are the equivalents to 4042BDC?

A functional alternative is the 74FCT573APC, an 8-bit D-type transparent latch with tri-state outputs from the 74FCT family. It is not pin-compatible with the 4042BDC — the 4042BDC is a 4-function D latch in the 4000-series CMOS family — but it serves a similar storage/latching role in digital designs. For a direct 4000-series replacement, look at other 4042 variants (e.g., CD4042) with the same logic function and package style.

What is the function of the 4042BDC?

The 4042BDC is a D latch with four independent latch functions. Each latch captures the logic level on its D input when the clock is active and holds that state until the clock toggles again. It is used for temporary data storage, register implementation, and control-bit latching in CMOS logic systems.

How do I get current pricing and availability for 4042BDC?

Current pricing and availability are confirmed at the time of quote. Submit an RFQ through the distributor — the response will include the per-unit price, minimum order quantity, and estimated lead time based on real-time stock positions.
