SN74LS674N

Shift Registers Overview

The SN74LS674N is a serial-out shift register from the Texas Instruments 74LS series. It features a 16-bit architecture with tri-state outputs and parallel-to-serial conversion capability. The device operates on a single power supply ranging from 4.75V to 5.25V. It utilizes bipolar LS-TTL technology and is housed in a 24-pin PDIP package designed for through-hole mounting. The component supports an operating temperature range of 0°C to 70°C.

Shift Registers Feature Summary

• Provides 16-bit data shifting functionality with parallel input and serial output options.
• Features tri-state outputs to facilitate bus-driven systems and signal isolation.
• Utilizes low-power Schottky (LS) TTL technology for efficient operation.

Shift Registers Applications

• Parallel-to-serial data conversion in digital communication interfaces
• Serial-to-parallel data expansion for peripheral control
• General-purpose shift register applications in logic circuits

Shift Registers Procurement Notes

Verify component authenticity due to discontinued status. Confirm package integrity as the SN74LS674N is no longer manufactured. Check for compatible replacements like the SN74LS674DW if surface-mount solutions are required. Ensure specifications match legacy system requirements before integration.

Shift Registers Selection Notes

Select this component for designs requiring 16-bit serial shifting with tri-state output control. Verify compatibility with existing 5V logic levels and through-hole assembly processes. Consider the SN74LS674DW alternative for surface-mount implementations while maintaining functional equivalence within the 74LS family.
