Vue d'ensemble

Description

The SN74HC164DR is an 8-bit serial-in, parallel-out shift register from Texas Instruments, part of the HC (High-speed CMOS) family. It is designed for high-speed digital applications, operating from a supply voltage of 2V to 6V. The device features two main modes of operation: data can be shifted in serially through the DS (serial data input) pin and output in parallel on the Q0 to Q7 pins.
It has a clock input (CLK) that controls the timing of data shifts, and a clear input (CLR) to reset all outputs to low state. The HC164 provides low power consumption and high noise immunity, making it suitable for a variety of applications, including LED control, data storage, and digital signal processing.
The package designation 'DR' indicates a TSSOP (Thin Shrink Small Outline Package) form factor, which is compact for space-constrained designs. Overall, the SN74HC164DR is ideal for users needing efficient, reliable data handling in electronics projects.

Features

The SN74HC164DR is an 8-bit shift register from Texas Instruments, featuring the following key attributes:
1. 8-Bit Shift Register: It can shift data serially into or out of the device.
2. Parallel Input/Output: Supports parallel loading of data.
3. High-Speed Operation: Typical propagation delay is 15 ns at 5V.
4. Wide Operating Voltage Range: Functions from 2V to 6V.
5. Low Power Consumption: Designed for low-quiescent current operation.
6. DIP and SOIC Packaging: Available in various packages for versatility in design.
7. Single Supply Operation: Operates with a single power supply.
8. Active-Low Outputs: The outputs are active-low, making it suitable for various applications.
9. Logic Compatibility: Compatible with standard CMOS or TTL logic levels.
10. Shift Direction Control: Supports right-shifting of bits based on control signals.
These features make the SN74HC164DR suitable for a variety of applications, including data processing, control systems, and digital circuit designs.

Package

The SN74HC164DR is housed in a SOIC (Small Outline Integrated Circuit) package. Specifically, it comes in a 14-pin SOIC package, suitable for surface mounting.

Pinout

The SN74HC164DR is an 8-bit serial-in, parallel-out shift register. It has a total of 16 pins. The key pin functions are as follows:
1. Pins 1-8 (Q0-Q7): These are the parallel output pins, where the shifted data appears.
2. Pin 9 (GND): Ground pin.
3. Pin 10 (Q7'): Inverted output of Q7.
4. Pin 11 (SRCLR): Asynchronous clear input; when low, it resets all outputs to low.
5. Pin 12 (SRCLK): Shift register clock input; data is shifted on the rising edge.
6. Pin 13 (SER): Serial data input; data is shifted in from this pin.
7. Pin 14 (OE): Output enable; when low, outputs are enabled (active).
8. Pin 15 (VCC): Power supply pin, typically +2V to +6V.
9. Pin 16: Not connected.
This device is widely used for applications requiring data storage and transfer.
