SN74LS195ADR

Shift Registers Overview

The SN74LS195ADR is a universal 4-bit parallel-access shift register manufactured by Texas Instruments. It operates within the standard TTL logic family and features asynchronous master reset functionality. The device supports both synchronous serial data transfer via J, K inputs to the first stage and parallel data loading. It utilizes Schottky diode clamped processes for high-speed performance, offering typical shift frequencies of 39 MHz. The component includes input clamp diodes to limit high-speed termination effects and provides complementary serial shift right outputs.

Shift Registers Feature Summary

• Universal 4-bit shift register with parallel access capabilities
• Asynchronous master reset function for immediate clearing
• J, K inputs allow for fully synchronous serial data transfers
• Schottky diode clamped process ensures high-speed operation

Shift Registers Applications

• Register applications requiring parallel data access
• Counting circuits utilizing synchronous or serial modes
• Data storage systems needing asynchronous reset control

Shift Registers Procurement Notes

Verify the specific suffix 'ADR' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with existing TTL voltage levels and interface requirements. Confirm RoHS compliance status as per the latest environmental declarations. Cross-reference the part number with official Texas Instruments documentation to validate availability and manufacturing status before procurement.

Shift Registers Selection Notes

Select this component when a 4-bit shift register with parallel load capability is required in a TTL environment. It is suitable for designs needing high-speed shifting up to 39 MHz. Consider the asynchronous reset feature if immediate clearing is necessary. Verify that the SOIC-16 package fits the board layout constraints. Compare against other 74LS series parts if different bit widths or output types are needed.

Shift Registers Part Context

This part belongs to the Texas Instruments 74LS series of low-power Schottky logic devices. It is functionally equivalent to the generic 74LS195 specification. The 'ADR' suffix typically denotes a surface-mount SOIC-16 package supplied in a reel format. It is designed for general-purpose digital logic applications requiring reliable TTL-compatible performance.

Shift Registers Replacement Considerations

Direct substitutes include the SN74LS195AD from Texas Instruments. Other manufacturers such as ON Semiconductor and Motorola offer compatible 74LS195 variants. Verify pinout and electrical characteristics match before substitution.
