Frequently Asked Questions
What is the data flow direction of the SN74LV164APWG4?
The SN74LV164APWG4 is an 8-bit serial-in, parallel-out shift register with right-shift data flow. Serial data enters through the AND-gated A and B inputs on each clock rising edge and is shifted toward Q7, with all 8 bits simultaneously available on the parallel outputs for loading external devices.
What are the AND-gated serial inputs (A and B) used for?
The SN74LV164APWG4 has two serial data inputs (A and B) that are internally AND-gated before the first shift register stage. Both inputs must be HIGH to shift a logic 1 into the register. This enables the B input to be used as a data enable/gate signal while A carries the data, simplifying circuit design.
What supply voltage range does the SN74LV164APWG4 support?
The SN74LV164APWG4 operates from 1.65V to 5.5V supply voltage, covering 1.8V, 2.5V, 3.3V, and 5V logic system rails. This wide range makes it compatible with both modern low-voltage microcontrollers and legacy 5V digital systems without requiring voltage translation.
What is the maximum clock frequency of the SN74LV164APWG4?
The SN74LV164APWG4 supports a maximum clock frequency of 40MHz at 3.3V supply, enabling fast serial-to-parallel conversion suitable for SPI-interfaced output expansion, high-speed LED matrix scanning, and other applications requiring rapid shift register data loading.
