CD4508BM

Latches Overview

The CD4508BM is a dual D-type transparent latch integrated circuit manufactured by Texas Instruments. It belongs to the 4000B series of CMOS logic devices and features two independent circuits configured as 8-bit latches. The component operates within a supply voltage range of 3V to 18V and supports a propagation delay of 50ns. It provides standard outputs with high and low currents of 6.8mA each. Designed for through-hole mounting, it utilizes a 24-PDIP package and functions reliably across an extended temperature range from -55°C to 125°C.

• General-purpose digital logic buffering

Latches Procurement Notes

Verify the specific suffix against official documentation, as variations may indicate different packaging or environmental compliance standards. Confirm that the requested part matches the exact pinout and electrical specifications required for your design. Check for any recent product change notices regarding manufacturing site updates or material composition changes. Ensure compatibility with your assembly processes if sourcing from third-party distributors.

Latches Selection Notes

Select this component when a dual 8-bit latch solution is required for parallel data retention. Consider the 24-PDIP package for prototyping or applications requiring through-hole assembly. Evaluate the 50ns propagation delay to ensure it meets the timing constraints of your system clock. Verify that the 6.8mA output current is sufficient for driving the connected load without external buffering.

Latches Part Context

This device is part of the extensive 4000B series of CMOS logic ICs produced by Texas Instruments. The series is widely recognized for its robust performance and compatibility with various digital logic families. The CD4508 specifically addresses the need for dual independent latching functions, offering a compact alternative to using separate single-channel latch components in complex digital designs.

Latches Replacement Considerations

The CD4508BM96 is listed as a similar replacement option. Verify pin compatibility and electrical parameters before substitution. Ensure the alternative component meets the same voltage and temperature requirements.
