SN74LS195ADR2

Shift Registers Overview

The SN74LS195ADR2 is a Low Power Schottky (LS) series universal 4-bit parallel-access shift register manufactured by onsemi. It features complementary serial shift right outputs and J, K inputs for the first stage. The device supports fully synchronous serial or parallel data transfers and includes an asynchronous master reset. It utilizes a Schottky diode clamped process to achieve high speeds, with typical shift frequencies of 39 MHz. The component is compatible with all TTL products and offers input clamp diodes to limit high-speed termination effects.

Shift Registers Feature Summary

• Universal 4-bit shift register architecture supporting both serial and parallel data access modes
• Asynchronous master reset capability for immediate state initialization
• J, K inputs provided for the first stage to enable flexible serial loading options
• Schottky diode clamped process ensures high-speed operation and compatibility with standard TTL logic families

Shift Registers Applications

• Register applications requiring parallel data storage and retrieval
• Counting applications utilizing the shift register functionality
• Data transfer systems needing synchronous serial or parallel loading capabilities

Shift Registers Procurement Notes

Verify the manufacturer designation carefully, as the part number prefix 'SN' typically indicates Texas Instruments, while the model suffix 'ADR2' and brand 'onsemi' suggest a different origin. Confirm that the specific SN74LS195ADR2 variant matches your required pinout and electrical specifications against official datasheets from the actual supplier. Ensure the package type and temperature range align with your design constraints before procurement.

Shift Registers Selection Notes

Select this component when a 4-bit shift register with parallel access is required in a Low Power Schottky logic environment. It is suitable for designs needing high-speed performance up to typical 39 MHz shift frequencies. Consider its compatibility with existing TTL circuits and the need for asynchronous reset functionality. Evaluate the package availability and ensure the J, K input configuration meets the specific data entry requirements of the application.

Shift Registers Part Context

This component belongs to the 74LS195 family of universal 4-bit shift registers. It is part of the broader Low Power Schottky logic series, designed for high-speed digital applications. The device is functionally similar to other 4-bit parallel-access shift registers but is distinguished by its specific LS technology characteristics and onsemi manufacturing standards.

Shift Registers Replacement Considerations

Compatible substitutes include the 74LS195 from manufacturers such as Motorola, National Semiconductor, and Hitachi Semiconductor. Verify pin compatibility and electrical parameters before substitution.
