U74LVC07A
CMOS IC
HEX BUFFERS WITH
OPEN-DRAIN OUTPUTS

DESCRIPTION
The U74LVC07A contain six independent buffers with open
drain outputs. The outputs are open-drain and can be connected to
other open-drain outputs to implement active-LOW wired-OR or
active-HIGH wired-AND functions
Inputs can be driven from 1.8V, 2.5V, 3.3V, or 5V devices. This
feature allows the use of these devices as translators in a
mixed-system environment.

FEATURES
* Operate from 1.65V to 5.5V
* Inputs and open-drain outputs accept voltages to 5.5V
* Direct interface with TTL levels
* Ioff supports partial-power-down mode
