PCF8534A
Universal LCD driver for low multiplex rates
10. Limiting values
[1] Pins SDA, SCL, CLK, SYNC, SA0, OSC, and A0 to A2.
[2] Pins S0 to S59 and BP0 to BP3.
[3] Pass level; Human Body Model (HBM), according to Ref. 5 “
JESD22-A114”.
[4] Pass level; Charged-Device Model (CDM), according to Ref. 6 “
JESD22-C101”.
[5] Pass level; latch-up testing according to Ref. 7 “
JESD78” at maximum ambient temperature (T
amb(max)
).
[6] According to the NXP store and transport requirements (see Ref. 9 “
NX3-00092”) the devices have to be
stored at a temperature of +8 C to +45 C and a humidity of 25 % to 75 %. For long-term storage products
deviant conditions are described in that document.
CAUTION
Static voltages across the liquid crystal display can build up when the LCD supply voltage
(V
LCD
) is on while the IC supply voltage (V
DD
) is off, or vice versa. This may cause unwanted
display artifacts. To avoid such artifacts, V
LCD
and V
DD
must be applied or removed together.
Table 18. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134).
