SN74HC165DR SMD IC SHIFT REGISTER SOIC16 74165 SN74HC165DR

Product Overview:

A surface-mount, 8-bit parallel-load shift register integrated circuit designed for parallel-to-serial data conversion. It allows for the efficient conversion of multi-bit parallel data into a serial format for simplified data transmission or communication, making it highly suitable for I/O expansion in microprocessor systems.

Core Specifications:

Manufacturer: Texas Instruments

Package Type: Available in various packages including SOIC (D), SSOP (DB), PDIP (N), SOP (NS), and TSSOP (PW)

Function: 8-Bit Parallel-Load Shift Register

Input Channels: 8 Individual Parallel Data (A–H) Inputs

Control Interface: Direct Logic Input (Clock, Shift/Load, and Clock Inhibit)

Features:

• 8-bit parallel-in, serial-out data conversion

• Direct overriding load (data) inputs for flexible parallel access

• Gated clock inputs and clock-inhibit function

• Wide operating voltage range: 2 V to 6 V

• Complementary serial outputs ($Q_H$ and $\bar{Q}_H$)

• Low power consumption: 80 µA maximum $I_{CC}$

• High-speed performance (typical $t_{pd} = 13$ ns at 5 V)

Applications:

• Parallel-to-serial data conversion for serial bus interfaces

• Microprocessor I/O port expansion

• Data buffering and temporary storage

• Industrial control systems requiring serial data transmission

• General-purpose logic and sequential circuit design
