Product specification
32-bit buffer/line driver; 5 V input/output
tolerant; 3-state
74LVC32244A;
74LVCH32244A
DC CHARACTERISTICS
Over recommended operating conditions; voltage are referenced to GND (ground = 0 V).

All typical values are at V

C.
For bus hold parts the bus hold circuit is switched off when V
I
exceeds V
CC
allowing 5.5 V on the input terminal.
Valid for data inputs of bus hold parts only (LVCH32xxx-A).
For data inputs only. Control inputs do not have a bus hold circuit.
The specified sustaining current at the data input holds the input below the specified V
I
level.
The specified overdrive current at the data input forces the data input to the opposite logic input level.
