SN74AXC4T774: Output drive under Section 8.3.2 conditions?

David F. Chan

Part Number: SN74AXC4T774

Hi SLL,

Wanted to confirm what the expected output drive current of the SN74AXC4T774 would be when adhering to the Balanced High-Drive CMOS Push/Pull Outputs as defined in section 8.3.2 of the datasheet. Is this the 40uA combined supply current spec?

David,

As noted in electrical char spec, the device can output +/- 12mA per channel at 3Vcc .

The supply current is the current that flows into V_CCx and out of GND; this is independent from the output current.

The drive current that the device can achieve without exceeding the specified voltage drop can be found in the test conditions of V_OL/V_OH.
