CD4015BM

Shift Registers Overview

The CD4015BM is a dual 4-bit serial-in parallel-out shift register manufactured by Texas Instruments. It belongs to the 4000B CMOS logic series and operates within a supply voltage range of 3 V to 18 V. The device features two independent shift registers, each with four stages, housed in a 16-pin SOIC surface-mount package. It utilizes rising-edge clock triggering for data shifting and includes dedicated clear inputs for each register. The component supports operation across an extended temperature range from -55 °C to 125 °C.

Shift Registers Procurement Notes

Verify the specific suffix (e.g., BM96) against the required packaging format such as tape and reel or cut tape. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact pinout and electrical specifications defined in the official datasheet.

Shift Registers Selection Notes

Select this component when dual independent 4-bit shift functionality is required in a compact surface-mount package. Consider the wide operating voltage range suitable for various logic families. Verify that the push-pull output drive strength meets the load requirements of the connected circuitry without additional buffering.
