N74F194D,602

Shift Registers Overview

The N74F194D,602 is a 4-bit bidirectional universal shift register in the 74F logic family. It operates on a single supply voltage of 4.5V to 5.5V and supports an operating temperature range of 0°C to +70°C. The device features synchronous parallel and serial data transfer capabilities with asynchronous master reset functionality. It utilizes edge-triggered mode select inputs (S0, S1) to control shift left, shift right, parallel load, or hold operations. The component is housed in a 16-pin plastic small outline package.

Shift Registers Feature Summary

• Supports bidirectional shifting for both left and right data transfer modes
• Enables synchronous parallel loading of four bits simultaneously
• Includes an asynchronous master reset input to force outputs low
• Provides a hold mode to retain existing data without clock transitions

Shift Registers Applications

• High-speed CPU implementation
• Memory buffer registers
• Serial-to-parallel conversion circuits
• Parallel-to-serial conversion circuits

Shift Registers Procurement Notes

Verify the specific suffix '602' against manufacturer documentation to confirm package type and commercial grade specifications. Confirm that the 16-pin SOIC form factor matches the design requirements. Check current product status as legacy components may have limited availability or obsolescence notices from Nexperia or NXP USA Inc.

Shift Registers Selection Notes

Select this component when bidirectional shifting and parallel loading are required within the 74F logic family constraints. Ensure the system clock frequency does not exceed the maximum specified limits under the intended operating temperature conditions. Verify that the power supply voltage remains within the recommended 4.5V to 5.5V range for proper logic level operation.

Shift Registers Part Context

This part belongs to the 74F series of high-speed TTL-compatible logic devices originally developed by Philips Semiconductors. The 74F194 specifically addresses applications requiring versatile data movement and storage. The 'D' designation indicates the surface-mount SOIC package variant, while the '602' suffix typically denotes specific ordering or environmental compliance details defined by the manufacturer.
