74F164ASC

Overview

The onsemi 74F164ASC is an 8-bit serial-in, parallel-out shift register housed in a 14-lead Small Outline Integrated Circuit (SOIC) package. It operates within a supply voltage range of +4.5V to +5.5V and supports a typical shift frequency of 90 MHz. The device features asynchronous Master Reset functionality and gated serial data inputs. It is designed for fully synchronous data transfers triggered by the LOW-to-HIGH transition of the clock signal.

Feature Summary

• Features an asynchronous Master Reset input that clears all outputs independently of the clock signal.
• Includes a two-input AND gate for serial data entry, allowing either input to act as an active HIGH enable.
• Provides fully synchronous data transfer capabilities with edge-triggered operation.

Applications

• Serial-to-parallel data conversion
• Parallel output expansion
• Digital logic circuits requiring high-speed shifting

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package type. Check current availability status as manufacturing lifecycles may change. Ensure compliance with relevant environmental standards such as RoHS requirements before integration into final designs.

Selection Notes

Select this component when high-speed serial-to-parallel conversion is required within standard TTL logic families. Consider the 14-pin SOIC package for surface-mount assembly needs. Evaluate the operating temperature range and power supply constraints against system specifications. Compare propagation delays and maximum clock frequencies with alternative logic families if performance margins are tight.

Part Context

This part belongs to the 74F series of high-speed logic devices. It serves as a faster version of the standard 74F164. The device is manufactured under the Fairchild Semiconductor brand, which is now part of onsemi. It utilizes standard JEDEC MS-120 packaging dimensions for the narrow SOIC form factor.

Replacement Considerations

Direct substitutes include other 74F164 variants from different manufacturers. Verify pin compatibility and electrical characteristics before substitution. Cross-reference datasheets for propagation delay and power consumption differences. Ensure the replacement device supports the same 14-lead SOIC package configuration.
