SN74LV164APWR 8-bit serial-in, parallel-out shift register
The SN74LV164APWR is an 8-bit serial-in, parallel-out shift register from Texas Instruments, belonging to the LV (Low-Voltage) family, designed to efficiently convert serial data streams into parallel output formats. Operating within a wide supply voltage range of 2.0V to 5.5V, it is highly versatile for interfacing with various logic levels in mixed-voltage systems. This device features two serial data inputs (A and B) that are ANDed together internally, providing a built-in enable function, and an asynchronous master reset (MR) to clear all outputs to a low state. It is an essential component for data expansion, serial-to-parallel conversion, and I/O port expansion in digital systems, offering a simple and reliable method to control multiple outputs from a limited number of microcontroller pins.
This shift register clocks data on the low-to-high transition of the clock input (CP). With a typical operating frequency of up to 125 MHz at 5V, it supports high-speed data shifting. The AND-gated serial inputs allow one input to be used as an active-high enable for data entry through the other. The eight parallel outputs are standard CMOS push-pull types capable of driving up to 8 mA, sufficient to directly drive LEDs or serve as control signals.
SN74LV164APWR TI shift register Applications
1. LED Matrix and Display Drivers: Controls rows, columns, or segments in LED dot-matrix displays, seven-segment displays, or large LED arrays by serially loading pattern data.
2. I/O Port Expansion: Extends the number of available output pins from a microcontroller or FPGA to drive relays, switches, indicators, or other peripherals.
3. Data Conversion and Serial Interface: Converts serial data from communication interfaces (like SPI or UART) into parallel data for latches, memory addresses, or data buses.
4. Industrial Control Logic: Implements simple state machines, delay lines, or pattern generators in control panels, sensor interfaces, and automation systems.
5. Test and Measurement Equipment: Used as a digital pattern source or for configuring multiple test points and multiplexers in automated test systems.
