ELECTRICAL CHARACTERISTICS at T
A
= +25
°
C (unless otherwise specified).
NOTES:
Turn-off delay is influenced by load conditions. Systems applications well below the specified output loading may require
timing considerations for some designs, i.e., multiplexed displays or when used in combination with sink drivers in a totem
pole configuration.
Negative current is defined as coming out of (sourcing) the specified device terminal.
* All inputs simultaneously.
All unused inputs must be connected to ground. Pulldown resistors (≈ 10 k) are recommended for inputs that
are allowed to float while power is being applied to V
S
.
Complete part number includes a prefix (A or UDN) and a suffix (A or SLW) as follows:
UDN2981A, UDN2982A, UDN2982LW, or A2982SLW.
