Frequently Asked Questions
What is the maximum clock frequency of the SN74LS596N?
The SN74LS596N supports a maximum clock frequency of 20MHz (20,000,000 Hz) at nominal supply voltage. This makes it suitable for high-speed serial data shifting applications in digital logic systems.
What package type does the SN74LS596N come in?
The SN74LS596N is available in a 16-pin Dual-In-Line Package (DIP), also identified by JESD-30 code R-PDIP-T16. The through-hole DIP package offers easy prototyping and breadboard compatibility.
What is the difference between the registered and unregistered outputs on the SN74LS596N?
The SN74LS596N features registered parallel output latches that hold data stable independent of shift register activity, ensuring clean parallel reads. Additionally, it provides an unregistered serial shift-right output pin for cascading multiple devices to create wider shift register chains.
Can the SN74LS596N be used as a replacement for other 8-bit shift registers?
Yes, the SN74LS596N is a member of the Texas Instruments LS logic family and is pin- and function-compatible with equivalent 8-bit serial-in parallel-out shift registers in the same family. Always verify supply voltage range (typically 4.75V to 5.25V) and timing parameters before substitution.
