It provides serial-to-parallel data conversion with two stages: an 8-bit shift register that accepts serial data on the rising edge of the shift register clock (SRCLK), and an 8-bit output latch that captures the shift register contents on the rising edge of the register clock (RCLK). The 3-state outputs can be placed in high-impedance via the output enable (OE) pin. A Q7' serial output enables daisy-chaining multiple 74HC595 devices for unlimited output expansion. The active-low shift register clear (SRCLR) resets the shift register independently of the output latch. The device operates from 2V to 6V with 78MHz typical shift frequency at 4.5V.","working_principle":"The SN74HC595N consists of two 8-bit registers: the shift register and the output latch register. Serial data on the SER (DS) input is shifted into the shift register on each rising edge of SRCLK. The data propagates from bit 0 through bit 7, with the bit 7 value appearing on the Q7' output for cascading to the next device. When RCLK rises, the entire shift register content is transferred simultaneously to the output latch register, updating all 8 outputs (Q0-Q7) at once. This two-stage architecture allows new data to be shifted in while the current output remains stable, preventing flicker in display applications. The SRCLR pin asynchronously clears the shift register to all lows when driven low, but does not affect the output latch, allowing selective clearing. The OE pin controls the 3-state output buffers; when OE is high, all Q0-Q7 outputs are in high-impedance, while the internal latch data and Q7' remain active. The 6mA output drive capability can directly drive LEDs, relay coils, and other low-current loads without additional buffers.","pin_description":"\n

        The 74595 is a 8-Bit Shift Register with Output Latches and 3-State Output. Family variants span from the original LS TTL (5V only) to modern LVC\/AUP (down to 0.8V). HC and HCT versions offer 2-6V CMOS operation with HCT providing TTL-compatible input thresholds for mixed 5V systems. CD4000-series equivalents offer the widest 3-18V supply range at the cost of lower switching speed. DIP packages (N suffix) are through-hole; SOIC (D suffix) and TSSOP are surface-mount.<\/p>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7850","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=7850"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7850\/revisions"}],"predecessor-version":[{"id":8210,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7850\/revisions\/8210"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=7850"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=7850"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=7850"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=7850"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
