Frequently Asked Questions
What is the function of the ABT16245?
It contains sixteen non-inverting bidirectional buffers with 3-STATE outputs, designed for bus operation.
How does the device operate in a high impedance (HIGH-Z) state?
Setting the OE inputs causes both A and B ports to enter a high impedance 'X' state.
What is the recommended supply voltage range?
The specified operating condition for the Supply Voltage (VCC) is 4.5V to 5.5V.
Does it provide full 16-bit operation capability?
Yes, by shorting together the separate control inputs for A and B gives full 16-bit operation.
