PCA85276
Automotive 40 x 4 LCD driver
12. Static characteristics
[1] LCD outputs are open-circuit; inputs at V
SS
or V
DD
; external clock with 50 % duty factor; I
2
C-bus inactive.
[2] For typical values, see Figure 23
.
[3] The I
2
C-bus interface of the PCA85276 is 5 V tolerant.
[4] When tested, I
2
C pins SCL and SDA have no diode to V
DD
and may be driven to the V
I
limiting values given in Tabl e 1 8 (see Figure 22
as well).
[5] Propagation delay of driver between clock (CLK) and LCD driving signals.
[6] Periodically sampled, not 100 % tested.
[7] Outputs measured one at a time.
