TLC2933A - TEST pin (8 pin)

Other Parts Discussed in Thread: TLC2933A

Hello,

My customer has a question about TLC2933A.

[Background]

They have used TLC2933.

However, this device became NRND.

So we promote a change to TLC2933A.

TLC2933A is pin compatible with TLC2933, but there is a concern.

<TLC2933 ... Their PCB>

2pin : TEST... Connect to GND

8pin : NC ... Floating

<TLC2933A ... My comments>

2pin : SELECT ... When SELECT connect to GND, the output frequency is x1. This does not any problem.

8pin : TEST ... Connect to GND (Datasheet). This is a problem.

[Q]

Is it a problem to leave TEST pin ?

Must it be connected to GND ?

Best Regards,

Hiroshi Katsunaga
