SN74GTL2014: DIR = low and VREF = 0V

user4979989

Part Number: SN74GTL2014

Hi Sir,

Could you help to check my customer's question in below?

B input port is pull up to 1.05V

When DIR = low and VREF = 0V, what is the VTT value? Do we have build-in VTT value? Port B ViL will be?

Thank you.

This device does not care about the actual V_TT value; it simply compares the B input voltages to the V_REF voltage.

The minimum V_REF voltage is 0.5 V. With V_REF = 0 V, it will not work at all.
