Frequently Asked Questions
What is the maximum output sink current of the SNJ54LS145J?
The SNJ54LS145J open-collector outputs can sink up to 80 mA at a maximum output low voltage (VOL) of 3 V, allowing direct driving of LEDs, lamps, and other moderate-current loads without external transistors.
What package does the SNJ54LS145J use and what are its pin count and dimensions?
The SNJ54LS145J is housed in a 16-pin ceramic dual-in-line package (CDIP), designated JESD-30 code R-CDIP-T16. The ceramic body provides superior thermal stability and reliability compared to plastic DIPs, making it suitable for harsh environments.
What logic family does the SNJ54LS145J belong to and what are its typical applications?
The SNJ54LS145J belongs to the Low-power Schottky (LS) TTL family and functions as a BCD-to-decimal decoder/driver. It is commonly used in seven-segment display decoding, numeric indicator driving, multiplexed BCD data routing, and any application requiring conversion of 4-bit BCD inputs to 10 active-low decimal outputs.
Is the SNJ54LS145J RoHS compliant and what is its lead finish?
The SNJ54LS145J carries a Pb-free code of 'Yes' per JESD-609 code e0, indicating the component meets RoHS lead-free requirements. Always verify with the specific date code and distributor documentation for full compliance confirmation.
What is the recommended load capacitance for the SNJ54LS145J and how does it affect performance?
The specified load capacitance (CL) for the SNJ54LS145J is 45 pF. Operating with capacitive loads exceeding this value will increase propagation delay and output transition times, so PCB trace lengths and parasitic capacitance should be minimized to maintain rated switching speeds.
