74F164ASJX

Overview

The onsemi 74F164ASJX is an 8-bit serial-in, parallel-out shift register belonging to the 74F logic family. It operates within a supply voltage range of +4.5V to +5.5V and supports a maximum clock frequency of 80 MHz at standard operating temperatures. The device features asynchronous Master Reset functionality and gated serial data inputs. It is housed in a 14-lead Small Outline Package (SOP) with package number M14D.

Feature Summary

• High-speed 8-bit serial-to-parallel conversion capability
• Asynchronous Master Reset for immediate output clearing
• Gated dual-input serial data entry mechanism

Applications

• Data storage applications requiring serial input and parallel output
• Digital signal processing systems utilizing high-speed shifting
• Communication interfaces managing serial data streams

Procurement Notes

Verify that the ordering code includes the 'X' suffix to confirm tape and reel packaging availability. Ensure the specific SOP package variant matches the required board layout dimensions. Confirm compliance with RoHS standards and check for any specific environmental classifications relevant to the manufacturing batch before finalizing procurement orders.

Selection Notes

Select this component when high-speed operation near 90 MHz is required compared to standard 74F variants. The SOP package offers a compact footprint suitable for space-constrained designs. Consider the 74F series characteristics for faster switching speeds relative to other logic families while maintaining compatibility with standard 5V logic levels.

Part Context

This part belongs to the 74F164A family of shift registers manufactured by Fairchild Semiconductor, now part of onsemi. The 'X' suffix specifically denotes tape and reel packaging options. The device serves as a high-performance alternative to the standard 74F164, offering improved speed specifications for demanding digital logic applications.

Replacement Considerations

Direct substitutes include the 74F164ASC and 74F164ASJ from the same manufacturer family. Verify pinout compatibility and electrical specifications against the original design requirements before implementing any cross-manufacturer replacements.
