MM74HC165SJX

Shift Registers Overview

The MM74HC165SJX is an 8-bit parallel-in/serial-out shift register manufactured by Fairchild Semiconductor. It operates within a supply voltage range of 2V to 6V and supports surface-mount installation in a 16-TSSOP package. The device features asynchronous parallel loading, synchronous serial input, and complementary serial outputs (Q7 and Q7_bar). It includes a clock enable function and is compatible with LSTTL logic levels.

Shift Registers Feature Summary

• Asynchronous 8-bit parallel load capability for immediate data capture
• Synchronous serial input with gated clock structure allowing flexible control
• Complementary serial outputs providing both true and inverted signals

Shift Registers Applications

• Parallel-to-serial data conversion in digital systems
• Expansion of I/O ports via cascading configurations
• Input scanning for keypads or switch matrices

Shift Registers Procurement Notes

Verify the manufacturer part number against ON Semiconductor documentation due to corporate integration. Confirm that the suffix 'SJX' corresponds to the specified 16-TSSOP surface-mount package. Ensure compatibility with existing design specifications before procurement.

Shift Registers Selection Notes

Select this component for applications requiring reliable parallel-to-serial conversion with low power consumption. Verify that the operating voltage range aligns with the system's power supply. Consider the package size constraints when designing the PCB layout for the 16-TSSOP form factor.

Shift Registers Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices. It is pin-compatible with Low Power Schottky TTL (LSTTL) standards, facilitating easy integration into legacy designs. The device adheres to JEDEC standard no. 7A for industrial logic IC specifications.

Shift Registers Replacement Considerations

Compatible substitutes include the NXP 74HC165 and Nexperia 74HC165. These alternatives offer identical functionality and pinouts. Verify package availability and ensure electrical parameters match the original design requirements.
