CD40194BPW

Shift Registers Overview

The CD40194BPW is a CMOS 4-bit bidirectional universal shift register manufactured by Texas Instruments. It operates within a supply voltage range of 3V to 18V and supports clock frequencies up to 6 MHz. The device features parallel-in/parallel-out capabilities, serial-in inputs for both left and right shifting, and independent clear and mode control inputs. It is housed in a 16-pin TSSOP surface-mount package and functions reliably across an industrial temperature range from -55°C to +125°C.

Shift Registers Feature Summary

• Supports bidirectional shifting with independent serial data inputs for left and right operations
• Provides parallel data loading capability via dedicated input pins
• Includes asynchronous master reset functionality to clear all storage elements

Shift Registers Applications

• Data buffering and temporary storage in digital systems
• Serial-to-parallel and parallel-to-serial data conversion
• Implementation of arithmetic logic units requiring shift operations

Shift Registers Procurement Notes

Verify the specific suffix 'BPW' corresponds to the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status as indicated by manufacturer documentation. Ensure the operating environment remains within the specified -55°C to +125°C temperature limits to maintain performance integrity.

Shift Registers Selection Notes

Select this component for applications requiring versatile shift register functionality with wide voltage tolerance. Consider the TSSOP-16 package for space-constrained surface-mount designs. Evaluate the 6 MHz maximum frequency against system clock requirements to ensure adequate timing margins.

Shift Registers Part Context

This part belongs to the Texas Instruments 4000B series of CMOS logic devices. It serves as a fundamental building block for sequential logic circuits. The device complements other members of the family by offering bidirectional control, distinguishing it from unidirectional shift registers.

Shift Registers Replacement Considerations

Cross-reference with CD40194BE for through-hole DIP alternatives. Verify pin compatibility with generic 40194 equivalents if sourcing from different manufacturers.
