SN74LS590NS is listed in the Counter Dividers range at ChipApex. The manufacturer field lists Texas Instruments. Its product description is IC COUNTER BIN 8BIT W/REG 16SO. Review the specifications below when checking this part for your BOM.
The SN74LS590NS is an 8-bit binary counter integrated circuit manufactured by Texas Instruments. It belongs to the LS logic series and features a synchronous counting mechanism with an input register and three-state outputs. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a maximum clock frequency of 20 MHz. It is housed in a 16-pin Small Outline Package (SOP) designed for surface mount technology, suitable for industrial temperature ranges from 0°C to +70°C.
Verify the specific suffix 'NS' confirms the SOP-16 surface mount package variant. Confirm RoHS compliance status through official documentation as indicated in distributor listings. Ensure the design accommodates the specified 4.75 V to 5.25 V operating voltage range and 0°C to +70°C temperature limits for reliable operation.
Select this component when an 8-bit synchronous binary counter with registered outputs is required in a surface mount application. The LS logic family offers standard TTL compatibility. Verify that the SOP-16 footprint fits the PCB layout constraints and that the 20 MHz maximum frequency meets the system timing requirements.
This part is part of the SN74LS590 series, which combines an 8-bit counter with an input register. It differs from non-registered counters by providing stable outputs via the register. The 'NS' designation specifically identifies the plastic small outline package version, distinguishing it from DIP or other package types within the same logical family.
