SN55451B: SN55451BJG

Part Number: SN55451B


Tool/software:

For our project involving the development of a Data Communication Unit, we require the SN55451BJG dual peripheral AND driver, particularly for its support of an extended temperature range of -10°C to +60°C. However, this part is currently out of stock.

An alternate part, SN75451BD, has been suggested. Unfortunately, its specified operating temperature range is 0°C to 70°C, which does not meet our requirement for negative temperature operation.

We request your guidance in identifying a suitable replacement that meets the required temperature specifications or an alternative solution to address this issue.

  • Penilop,

    Given the age of the device (58 years) we are going to be limited on replacements. What is the end equipment? Would a device like the ULQ2003-Q1 work? I realize this has multiple channels, but it would likely be one of the better replacements. Could you let me know a bit more about the loading conditions?

    Best Regards,
    Tim
