A multiplexed tube dissipation example follows:
VCC = 5V ±5%, VBB = 36V to 42V, A = 12, G = 8,
IANODE = 0.4mA, IGRID = 24mA
PD = (5.25V x 1mA)+ (42V x 1.4mA) +
((2.5V x 0.4mA/25mA) x 0.4mA x 12) +
((2.5V x 24mA/25mA) x 24mA) = 122mW
Thus, for a 28-pin wide TSSOP package (TJA = 1 / 0.0128
= 78.125°C/W from Absolute Maximum Ratings), the
maximum allowed ambient temperature TA is given by:
TJ(MAX) = TA + (PD x TJA) = 150°C = TA + (0.122 x
78.125°C/W)
So TA = +140.5°C.
This means that the driver can be operated in this
application up to the MAX6921/MAX6931s’ +125°C
maximum operating temperature.
Power-Supply Considerations
The MAX6921/MAX6931 operate with multiple power-
supply voltages. Bypass the VCC, VBB, and VSS
(MAX6931 only) power-supply pins to GND with 0.1µF
capacitors close to the device. The MAX6931 may be
operated with VSS tied to GND if a negative bias supply
is not required. For multiplex applications, it may be
necessary to add an additional bulk electrolytic capaci-
tor of 1µF or greater to the VBB supply.
Power-Supply Sequencing
The order of the power-supply sequencing is not impor-
tant. The MAX6921/MAX6931 will not be damaged if
any combination of VCC, VBB, and VSS (MAX6931 only)
is grounded while the other supply or supplies are
maintained up to their maximum ratings. However, as
with any CMOS device, do not drive the MAX6921/
MAX6931s’ logic inputs if the logic supply VCC is not
operational because the input protection diodes clamp
the signals.
Cascading Drivers (MAX6921 Only)
Multiple MAX6921s may be cascaded, as shown in the
Typical Application Circuit, by connecting each driver’s
DOUT to DIN of the next drivers. Devices may be cas-
caded at the full 5MHz CLK speed when VCC
≥ 4.5V.
When VCC <4.5V, the longer propagation delay (tDO)
limits the maximum cascaded CLK to 4MHz.
