MC14094BFELG

Shift Registers Overview

The MC14094BFELG 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 buffers controlled by an Output Enable signal. Data shifts on the positive clock transition, while latching occurs on the negative strobe transition. The device operates within a DC supply voltage range of -0.5 V to +18.0 V and supports an ambient temperature range of -55 °C to +125 °C. It is housed in a 16-SOEIAJ package and supplied in tape and reel quantities of 2000 units.

Shift Registers Feature Summary

• Combines an 8-stage shift register with individual data latches and three-state output buffers
• Provides dual serial outputs (QS and Q'S) for high-speed and low-speed cascaded systems
• Features asynchronous data latching triggered by the negative transition of the strobe input
• Includes input diode protection and pin-for-pin compatibility with CD4094B

Shift Registers Applications

• Serial-to-parallel data conversion
• High-speed cascaded digital systems using QS output
• Low-speed cascaded digital systems using Q'S output
• Driving low-power TTL or Schottky TTL loads

Shift Registers Procurement Notes

Verify the specific ordering suffix 'F' corresponds to the SOEIAJ-16 package configuration as defined in the manufacturer's documentation. Confirm that the procurement channel provides the standard 2000-unit tape and reel packaging format associated with this suffix. Ensure compliance with RoHS standards and lead-free requirements specified for this component variant.

Shift Registers Selection Notes

Select this component when an 8-bit shift register with parallel storage and tri-state control is required. It is suitable for applications needing dual serial outputs for different cascade speeds. Verify that the operating voltage and temperature ranges align with system constraints. Consider the SOEIAJ-16 package dimensions for PCB layout compatibility.

Shift Registers Part Context

This part belongs to the MC14094B family of CMOS logic devices. It serves as a functional equivalent to the industry-standard CD4094B.

Shift Registers FAQ

How does the data latching mechanism function?

Data from the shift register stages is latched onto the parallel outputs upon the negative transition of the strobe input. The data propagates through the latch while the strobe signal remains high.

What is the difference between the QS and Q'S outputs?

The QS output transfers data from the seventh stage during the positive clock transition, intended for high-speed cascading. The Q'S output shifts data during the following negative clock transition, designed for low-speed cascading.
