Description

The SN74HC164D is an 8-bit serial-in, parallel-out shift register, part of Texas Instruments' 74HC family of high-speed CMOS logic devices. It features a parallel data output, allowing data input to be shifted in serially and then output in parallel. This device operates with a supply voltage range of 2V to 6V and is known for low power consumption and high-speed performance.
The SN74HC164D has two main control inputs: the clock (CLK) and the clear (CLR) inputs. On each clock pulse, data present at the serial input is shifted into the register, with the output reflecting the current state of the register. It also includes an asynchronous clear function to reset all outputs to a low state.
Common applications include data storage, digital signal processing, and interfacing with microcontrollers. Its compact package and reliable operation make it a popular choice in various electronic designs.

Features

The SN74HC164D is an 8-bit serial-in, parallel-out shift register from Texas Instruments. Key features include:
1. Data Storage: It can store 8 bits of data, which can be shifted in serially and output in parallel.
2. High-Speed Operation: It operates at high-speed with a maximum clock frequency of over 20 MHz.
3. Wide Voltage Range: The device operates on a supply voltage range of 2V to 6V.
4. Low Power Consumption: It offers low static power dissipation, making it suitable for battery-operated devices.
5. TTL Compatibility: It is compatible with TTL voltage levels, ensuring easy interfacing with other logic families.
6. Parallel Output: The outputs can be used to drive LEDs or other devices directly.
7. Asynchronous Reset: The register features an asynchronous reset, enabling quick clearing of the stored data.
These features make the SN74HC164D ideal for applications in digital circuits, data conversion, and control systems.

Package

The SN74HC164D is typically available in a DIP (Dual In-line Package) format, specifically a 14-pin package. It can also be found in other package types like TSSOP and SOIC.

Pinout

The SN74HC164D is an 8-bit serial-in, parallel-out shift register. It features a total of 16 pins. Here are the key pin functions:
1. Pins 1-8 (Q0-Q7): These are the parallel output pins where the stored data can be accessed.
2. Pin 9 (GND): Ground connection.
3. Pin 10 (DS): Serial data input for shifting data into the register.
4. Pin 11 (SHCP): Shift clock input; on the rising edge, data is shifted from DS to the outputs.
5. Pin 12 (STCP): Storage clock input; on the rising edge, data is transferred from the shift register to the output register.
6. Pin 13 (MR): Master reset; when low, it resets the outputs to low regardless of other inputs.
7. Pin 14 (VCC): Positive power supply connection.
8. Pins 15-16: Not connected or used for internal purposes.
This device is commonly used for data storage and transfer in various digital applications.
