SNJ54H30J is a popular integrated circuit (IC) component manufactured by Texas Instruments. This particular IC is a member of the 54H family and is designed using bipolar technology. SNJ54H30J is a 8-input positive-NAND gate, which means it performs the logical NAND operation on its inputs.
Key features of SNJ54H30J:
1. Input and Output: SNJ54H30J has eight input pins, labeled as A1, A2, A3, A4, A5, A6, A7, and A8. Its output is denoted by the pin labeled as Y.
2. Logic Functionality: Being a positive-NAND gate, this IC performs a NAND operation on all of its inputs. The output, Y, will be high (logical '1') when all inputs are low (logical '0'). Otherwise, the output will be low (logical '0').
3. Open Collector Output: The output pin, Y, operates in an open collector configuration, which means it can only sink current but cannot source it. Therefore, an external pull-up resistor is required to provide a high voltage level when the output is in the inactive state.
4. Supply Voltage: SNJ54H30J operates with a wide range of power supply voltages, typically between 4.75 and 5.25 volts. However, it is essential to consult the datasheet for precise specifications
