SN74LS195AD

Shift Registers Overview

The SN74LS195AD is a universal 4-bit shift register manufactured by ON Semiconductor. It utilizes the Schottky diode clamped process to achieve high speeds, offering a typical shift right frequency of 39 MHz. The device features asynchronous master reset and J, K inputs for the first stage, enabling fully synchronous serial or parallel data transfers. Input clamp diodes are included to limit high-speed termination effects. It is compatible with all ON Semiconductor TTL products.

Shift Registers Procurement Notes

Verify that the component is sourced from authorized channels to ensure authenticity. Confirm the package type matches the required PCB footprint. Check for RoHS compliance status if environmental regulations apply to the specific manufacturing batch. Ensure the operating temperature range meets the system requirements.

Shift Registers Selection Notes

Select this component when a 4-bit shift register with high-speed performance is required. The Schottky technology provides faster switching compared to standard LS logic. Consider the availability of J, K inputs for complex state transitions. Verify compatibility with existing TTL logic levels in the design.

Shift Registers Part Context

This part belongs to the 74LS series of low-power Schottky logic devices. It is functionally similar to other 4-bit shift registers like the 74LS194 but offers specific J, K input configurations. The SN74LS195AD variant indicates an SOIC-16 package version of the standard SN74LS195A logic gate.
