UCD3138: UCD3138 SYNC (GPIO) response time

user5952333

Part Number: UCD3138

Hello.

Please tell me the response time from when the SYNC signal of GPIO becomes Low level in UCD3138RGCR until it is detected.

Also, what are the low level and high level thresholds?

Best regards.

I know it's very quick and hasn't caused issues when we use it, but I can't remember the exact timing. Let me find an answer for you.

Hello,

The voltage levels are VIH=2.1V (min) and VIL=1.1V (max), like in any other digital input.

The delay is about 64 nS.
