| Market Reality | The 74HC595 is the expander of the microcontroller world: three pins in, eight latched outputs out, cascaded to infinity - the part behind LED matrices, relay banks, seven-segment displays and every hobby board that ran out of GPIO. The family substitution is the cleanest in logic: HC and HCT share a die and differ only in input thresholds (CMOS against TTL levels), the LS ancestor keeps the pinout at 5V with vintage power draw, and cascading works the same across all of them. Two parts sit nearby and cause most of the confusion: the TPIC6B595, a power version whose outputs sink instead of source and whose logic sense is inverted, and the CD4094, an older CMOS register from a different school with a strobe instead of a latch clock. | The 74HC595 is the expander of the microcontroller world: three pins in, eight latched outputs out, cascaded to infinity - the part behind LED matrices, relay banks, seven-segment displays and every hobby board that ran out of GPIO.
