CD4042BDRG4

Latches Overview

The CD4042BDRG4 is a quad D-type transparent latch from the Texas Instruments 4000B series, housed in a 16-pin SOIC surface-mount package. It operates on a supply voltage range of 3V to 18V with a maximum static current of 4µA. The device features differential outputs and supports an operating temperature range from -55°C to +125°C. Propagation delay varies by voltage: 40ns at typical conditions, 300ns at 5V, 150ns at 10V, and 100ns at 15V. Output drive capabilities include 6.8mA for both high and low states.

Latches Feature Summary

• Contains four independent D-type transparent latches within a single integrated circuit.
• Provides differential output signals for each latch channel.
• Supports wide supply voltage operation suitable for various logic families.
• Designed for industrial-grade performance across extended temperature ranges.

Latches Applications

• Data storage and buffering in digital logic circuits
• Parallel-to-serial data conversion interfaces
• Timing control and synchronization systems
• Memory address latching in microprocessor systems

Latches Procurement Notes

Verify the presence of the 'G4' suffix to confirm lead-free composition and compliance with RoHS directives. Ensure the SOIC-16 package footprint matches the target PCB design. Confirm that the specified propagation delays align with system timing requirements under the intended supply voltage conditions.

Latches Selection Notes

Select this component when a compact surface-mount solution for multiple latches is required. The 4000B series offers robust noise immunity and wide voltage tolerance. Consider the 40ns propagation delay for moderate-speed applications. Verify thermal management needs given the extended temperature rating and power dissipation characteristics.

Latches Part Context

This part belongs to the CD4042B family of quad D-type latches. It serves as the surface-mount variant of the through-hole CD4042BE. The device is part of the broader 4000B CMOS logic series, known for low power consumption and compatibility with standard TTL levels at higher voltages.

Latches Replacement Considerations

CD4042BDR is the non-RoHS equivalent. CD4042BE is the through-hole alternative. MC14042B is a compatible option from other manufacturers.
