MC14094BF

Shift Registers Overview

The MC14094BF is an 8-stage shift/store register with three-state outputs manufactured by onsemi. It integrates an 8-stage shift register, a data latch for each stage, and three-state output buffers. The device operates within a supply voltage range of 3 V to 18 V. It features dual serial outputs (QS and Q) for cascading in high-speed or low-speed systems. Data shifts on the positive clock transition, while latching occurs on the negative strobe transition. The component supports push-pull outputs and is designed for serial-to-parallel data conversion applications.

Shift Registers Feature Summary

• Integrates an 8-stage shift register with individual data latches for storage capability
• Provides three-state outputs controlled by an Output Enable input for bus driving
• Features dual serial outputs (QS and Q) to support both high-speed and low-speed cascaded configurations
• Includes input diode protection to safeguard against transient voltage events

Shift Registers Applications

• Serial-to-parallel data conversion circuits
• High-speed cascaded digital systems utilizing QS output
• Low-speed cascaded digital systems utilizing Q output
• General-purpose shift register applications requiring stored data output

Shift Registers Procurement Notes

Verify the specific suffix 'BF' indicates the SOIC-16 surface mount package configuration as distinct from other variants. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the ordering part number matches the required pinout and electrical specifications for the target application design.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with storage and three-state output control is required. It is suitable for designs needing flexible cascading options via dual serial outputs. Consider the 3 V to 18 V operating range for compatibility with various logic families. Verify that the surface mount package fits the PCB layout constraints.

Shift Registers Part Context

The MC14094B belongs to the CMOS 4000 series logic family produced by onsemi. This series is characterized by wide power supply ranges and compatibility with standard TTL loads. The MC14094 variant specifically focuses on shift register functionality with added storage and output tri-stating capabilities, distinguishing it from basic shift registers like the CD4014B.

Shift Registers Replacement Considerations

The MC14094BF is pin-for-pin compatible with the CD4094B. Other equivalents may include the MC14094BDTR2G for tape-and-reel packaging or the MC14094BDR2G. Verify electrical parameters and package dimensions before substitution.
