CD4094BF3A

Shift Registers Overview

The CD4094BF3A is a CMOS 8-stage shift-and-store bus register manufactured by Texas Instruments. It features serial-to-parallel conversion with output latching and three-state control capabilities. The device operates within a supply voltage range of 3 V to 18 V and supports clock frequencies up to 2.5 MHz at 10 V, 3 MHz at 15 V, and 1.25 MHz at 5 V. It utilizes a 16-pin ceramic dual in-line package (CDIP) designed for through-hole mounting. The component functions on rising edge triggers and includes synchronous preset and reset mechanisms. It is rated for operation between -55 °C and +125 °C.

Shift Registers Feature Summary

• Provides serial data input converted into parallel outputs with storage capability
• Includes three-state parallel outputs controlled by an enable pin for bus interfacing
• Features synchronous preset and reset inputs for direct control of internal states
• Supports cascading via dedicated serial output pins for multi-stage expansion

Shift Registers Applications

• Serial-to-parallel data conversion in digital systems
• Display driver interfaces requiring latch and tri-state control
• Multiplexed output control circuits
• Data storage registers in microprocessor-based systems

Shift Registers Procurement Notes

Verify the F3A suffix indicates a military-grade ceramic DIP package when sourcing. Confirm RoHS compliance status as historical records may vary. Ensure the supplier provides traceability documentation for the specific lot code. Check for availability constraints as this variant may be subject to limited production runs or special order requirements.

Shift Registers Selection Notes

Select this component when a robust ceramic package is required for high-temperature environments exceeding standard plastic limits. The three-state output feature simplifies bus sharing compared to non-tri-state alternatives. Verify that the 4000 series logic voltage compatibility matches the system power rails. Consider the physical dimensions of the 16-pin CDIP housing during PCB layout planning.

Shift Registers Part Context

This part belongs to the CD4094B family of CMOS logic devices produced by Texas Instruments. It serves as a specialized shift register within the broader 4000 series architecture. The BF3A designation specifically denotes the ceramic dual in-line package variant intended for demanding operational conditions. It shares functional equivalence with other manufacturers' versions of the CD4094 but maintains TI-specific manufacturing standards.

Shift Registers Replacement Considerations

Compatible substitutes include the HEF4094B from NXP Semiconductors and the MC14094B from ON Semiconductor. These parts share identical logical functionality and pin configurations. Verify package compatibility if replacing the ceramic CDIP version with plastic equivalents.
