I74F164N,112

Shift Registers Overview

The I74F164N,112 is an 8-bit serial-in parallel-out shift register manufactured by NXP USA Inc. It operates on a 5V supply (4.5V to 5.5V) and features gated serial data inputs (Dsa, Dsb) that act as active High enables for data entry through the other input. The device shifts data one position to the right on each Low-to-High clock transition, with outputs Q0 through Q7 reflecting the shifted state. An asynchronous Master Reset (MR) input overrides all other functions to clear the register. The component supports a typical maximum clock frequency of 100MHz and includes buffered clock and data inputs for fully synchronous data transfer.

Shift Registers Feature Summary

• Gated serial data inputs allow flexible configuration where either input serves as an enable for the other
• Asynchronous Master Reset function clears all outputs regardless of clock or data states
• Buffered inputs ensure fully synchronous data transfer on rising clock edges
• Industrial temperature range availability extends operational reliability

Shift Registers Applications

• Cascading multiple units to form longer synchronous shift registers
• Serial-to-parallel data conversion in digital logic circuits
• Data storage and delay line applications requiring edge-triggered shifting

Shift Registers Procurement Notes

Verify the specific ordering suffix and package type against the manufacturer's current product specification before procurement. Confirm that the industrial temperature range variant matches the intended operating environment requirements. Ensure compatibility with standard 5V logic levels and check for any superseded documentation versions that may affect design integration.

Shift Registers Selection Notes

Select this component when an 8-bit serial-in parallel-out shift register with gated inputs is required. Consider the 100MHz typical shift frequency for high-speed applications. Verify that the 14-pin plastic DIP package fits the board layout constraints. Ensure the design accommodates the asynchronous reset functionality and the specific setup/hold time requirements relative to the clock signal.

Shift Registers Part Context

This part belongs to the 74F series of integrated circuits, which are known for fast switching speeds compared to standard TTL logic. The 74F164 specifically provides an 8-bit shift register solution with dual serial inputs. It is designed for general-purpose digital logic applications requiring reliable data shifting and parallel output distribution within standard commercial and industrial temperature ranges.

Shift Registers Replacement Considerations

Direct replacement options include the 74F164N from Philips Semiconductors and the 74F164D in SO package format. Verify pinout compatibility and electrical characteristics such as propagation delay and supply current when substituting.
