CD4042BF3A

Latches Overview

The CD4042BF3A is a quad D-type latch from the Texas Instruments CD4042B series, housed in a 16-lead hermetic dual-in-line ceramic package (CDIP). It features four independent transparent latches with separate data inputs and outputs. The device operates within a supply voltage range of 3 V to 18 V and supports an operating temperature range of -55°C to +125°C. Propagation delay varies with voltage: 300 ns at 5 V, 150 ns at 10 V, and 100 ns at 15 V. Static current is typically 20 µA, with low-level output current of 32 mA and high-level output current of -4.2 mA.

Latches Feature Summary

• Provides four independent transparent D-type latches for data storage applications.
• Features separate data input and output lines for each latch channel.
• Supports both inverting and non-inverting output configurations.

Latches Applications

• Military and defense electronic systems requiring radiation-hardened or hermetic components.
• High-reliability industrial control logic circuits.
• Spacecraft avionics and satellite communication subsystems.

Latches Procurement Notes

Verify the specific ordering suffix F3A to confirm the 16-lead hermetic ceramic dual-in-line package (CDIP) configuration. Ensure procurement channels are authorized for military-grade or hermetic component sourcing, as this packaging variant differs significantly from standard plastic packages. Confirm RoHS status and lead finish specifications against project requirements prior to ordering.

Latches Selection Notes

Select the CD4042BF3A when hermetic sealing is required for harsh environments or military specifications. This part belongs to the CD4042B family; verify compatibility with existing circuit designs regarding pinout and electrical characteristics. Consider the higher cost and availability constraints associated with ceramic packaged devices compared to standard plastic equivalents like the CD4042BE.

Latches Part Context

The CD4042BF3A is part of the CD4042B series, which includes variants in plastic DIP, SOIC, and TSSOP packages. The 'F3A' suffix specifically denotes the 16-lead hermetic ceramic dual-in-line package. Other active versions include CD4042BE (plastic DIP) and CD4042BDW (wide SOIC), offering different form factors for general-purpose applications.

Latches Replacement Considerations

For equivalent performance in a plastic package, consider the CD4042BE. For surface-mount applications, the CD4042BDW or CD4042BNSR may be suitable alternatives if hermeticity is not required. Verify that the replacement package maintains the same pinout and electrical specifications.
