Original question:
SN75160B: Discontinuance of Select RS485 Devices, PDN# 20230516001.3 (SN75160B, SN75161B)
Hi,
In the thread below, it was noted that " it would be possible to use strong transceivers like the CY74FCT245T or SN74ABT245B".
As an alternative to the SN75161BDW, could you tell me what to keep in mind as a peripheral circuit when using these IC?
Best Regards,
Nishie
Figure 12 of the SN75160B datasheet shows the voltage/current relationships that IEEE-488 requires of a GPIB output.
The CY74FCT245T or the SN74ABT245B are likely to work with GIPB devices. However, their outputs are not guaranteed to lie inside these limits, and the IEEE-488 specification might impose additional limits.
If you have a specific GPIB device that you want to keep working, then it would be possible to test it with the CY74FCT245T/SN74ABT245B, and this test is likely to be successful. But there is no guarantee. And it is certainly not possible to simply put these transceivers into a device and label it as "IEEE-488 compliant".
